This document provides details about the design and construction of a remote controlled motorized hydraulic jack. The summary is:
The remote controlled motorized hydraulic jack uses a 12V DC motor connected via a crankshaft to the hydraulic jack. The motor is powered by a 12V power supply and controlled remotely using a transmitter and receiver. The power supply steps down household AC voltage to 12V DC using a transformer, rectifier, and voltage regulators. The remote control allows single-person operation of the jack to lift vehicle tires without manual labor.
An automotive jack is a device used to raise all or part of a vehicle into the air in order to facilitate repairs. Most people are familiar with the basic car jack (manually operated) that is still included as standard equipment with most new cars. These days, a car jack is an important tool to have in our vehicle due to unknown upcoming event such as flat tire in our journey. Even so, people who like to rotate their tires themselves or who may install snow tires before the winter and remove them in the spring need to use a jack to perform the job. Changing a flat tire is not a very pleasant experience. Women have a much lighter skeleton that means, among other things, woman can’t pull more forces as well as men and are at greater risk of skeletal injuries. Usually the car purposely tries to get a flat tire at the least opportune moments.

Hydraulic Jack is a device that uses force to lift heavy loads. The primary
mechanism with which force is applied varies, depending on the specific type of
jack, but is typically a screw thread or a hydraulic cylinder. Jacks can be
categorized based on the type of force they employ: mechanical or hydraulic.
Mechanical jacks, such as car jacks and house jacks, lift heavy equipment and are
rated based on lifting capacity (for example, the number of tons they can lift).
Hydraulic jacks tend to be stronger and can lift heavier loads higher, and include
bottle jacks and floor jacks.

Design and Fabrication of Automatic Drain Cleanerijtsrd
This paper describes about the design and fabrication of automatic drain cleaner. There are a large number of machines used for removing out the wastes from drains. Nowadays, automation plays a vital role in all industrial applications. The automatic drain cleaner can be used in domestic, industry, large plants, irrigation and drainage cleaning system. In order to overcome the problems in manual drain cleaning, Automatic Drain Cleaning System is implemented to clean and control the drainage level. Every automatic drain cleaner has four main components, namely DC motor, 12 V battery, chain drives and shafts. The rotational speed of the drive shaft is 26 rpm. But in this paper, only shaft design is calculated. The required power from a motor to drive this shaft is 60 W. In designing shaft, chain tension, sprocket load and bearing load are taken into account and also bending moment and torque are included.

This project and implementation is very useful for long journey vehicle and this setup
helps to raise vehicle by using battery or engine power. An automatic pneumatichydraulic jack comprises a mini air compressor and automatic hydraulic jack to serve
as an on-vehicle tool where as the power of the battery on the vehicle is used to drive
the mini air compressor which compresses air to serve as its primary force. The air
enters an entry channel from an air inlet nozzle and passes to an air chamber via a
changeover valve to push a small air-oil piston, thus converting air pressure into
hydraulic pressure on the other side of the piston which enters into a large hydraulic
cylinder via a check valve and pushes a large piston. The downward movement of the
small air-oil piston causes engagement with and turns the changeover valve, thus
connecting the air chamber channel to an exhaust channel and the entry channel to the
storage tank channel which enables the oil storage tank to supply the small hydraulic
cylinder with oil under pressure and make the small air-oil piston move upwards when
the small hydraulic cylinder is filled with oil, the small air-oil piston turns the
changeover valve to connect the air entry channel to the air chamber channel again,
thereby completing the cycle. Such reciprocation converts the air pressure into
hydraulic pressure to push the big piston which in turn, jacks up the vehicle. To lower
the vehicle, an oil return screw is turned to allow the oil to return to the oil storage tank
via a return channel

One of the most important equipment used in transporting goods and people is the hydraulic lift. By the way of hydraulics, such lifts are able to carry heavy loads with great ease, and lift it vertically. Hydraulic lifts come in the form of passenger lift, service lifts (to carry goods to higher floors etc.
Hydraulic elevator systems lift a car using a hydraulic ram, a fluid-driven piston mounted inside a cylinder.

Power Quality Analysis of Vienna Rectifier for BLDC Motor Drive ApplicationIJPEDS-IAES
This paper presents the power quality improvements for a BLDC driver using
Vienna rectifier as front end converter. The major drawbacks in the BLDC
motor drive and non linear load applications are the line pollution and
depreciation of the power factor. The conventional power factor correction
method is not economical and efficient. It requires bulky components as load
changes and produce high THD and less Power factor. The front end
converter of BLDC bridge inverter drive is proposed by the Vienna rectifier,
which can contribute more significantly in improving the power factor and
reduce the line pollution. The Vienna rectifier topology is controlled by the
constant switching frequency control technique for wide range of load
variation and it reduces the THD, improve the power factor and provide a
steady DC link voltage to the bridge inverter to drive the BLDC motor. The
design calculation and performance characteristics of BLDC motor and
Vienna rectifier are verified by using Matlab simulation.

19. PRINCIPLE OF DC MOTOR
A DC motor is a dc machine working as a motor to convert dc electrical
energy into mechanical energy (dc) motor are very commonly used in cars, trucks,
aircrafts, etc. They are also used in large ratings, where wide range of speed
control is necessary.
When a conductor is carried a current and in lying in magnetic filed. Force
acting on the conductor. This is the principle of a Dc motor. The conductor is
housed in armature slots and current is applied from the dc source through brushes
and commutator. The field poles provide the magnetic field.
The construction of dc motor and generator are similar. However their
external appearance may be somewhat different. A motor has a rather closed
frame because it is may be operating in dusty environment and unskilled workers
may be working in its vicinity.
21. TYPES OF DC MOTOR
DC Shunt Motor:
This motor has medium starting torque, a speed regulation of 5 – 10 % and
excellent adaptability to adjustable speed service. It can be used for constant speed
drives like pumps, fans blowers, etc,. However for all these applications, a 3 phase
induction motor is preferable, because it ;is cheaper, more rugged and requires
lesser maintenance than dc motor. However a dc shunt motor is cheaper for low
speed drives. Moreover, whenever a wide range of speed control is required, dc
shunt motor is used. The main application of dc shunt motor is in steel and
aluminium, rolling mills and ward – Leonard speed control system.
Dc Series Motor:
This motor has a very high starting torque. Moreover it speed decreases
with increase in load torque. So that its power input remains more or less constant.
It is best suited for hoist cranes and traction. Speed control is generally obtained
through armature control. They are used for battery-powered vehicles.
22. Compound Motor:
A differential compound is rarely used. The characteristics of a cumulative
compounds motor depend on the relative strength of series and shunt fields. It has
good starting torque and dropping speed – load characteristic. They can be used
for pulsating loads needing flywheel action, viz. shears, conveyors, crushers,
hoists, plunger pumps, etc., Whenever the supply voltage is likely to vary
considerably, a compound motor is preferred. Because its induction and
contribution to back emf, the series field helps in reducing the fluctuations of
current drawn from mains.
23. POWER SUPPLY UNIT
INTRODUCTION:
All the electronic components starting from diode to Intel IC’s only work
with a DC supply ranging from +5V to +12V. We are utilizing for the same, the
cheapest and commonly available energy source of 230V-50Hz and stepping
down, rectifying, filtering and regulating the voltage.
STEP DOWN TRANSFORMER:
When AC is applied to the primary winding of the power transformer, it can
either be stepped down or stepped up depending on the value of DC needed. In our
circuit the transformer of 230V/15-0-15V is used to perform the step down
operation where a 230V AC appears as 15V AC across the secondary winding.
Apart from stepping down voltages, it gives isolation between the power source
and power supply circuitries.
RECTIFIER UNIT:
In the power supply unit, rectification is normally achieved using a solid
state diode. Diode has the property that will let the electron flow easily in one
direction at proper biasing condition. As AC is applied to the diode, electrons only
flow when the anode and cathode is negative. Reversing the polarity of voltage
will not permit electron flow. A commonly used circuit for supplying large
amounts of DCpower is the bridge rectifier. A bridge rectifier of four diodes (4 x
24. IN4007) are used to achieve full wave rectification. Two diodes will conduct
during the negative cycle and the other two will conduct during the positive half
cycle, and only one diode conducts. At the same time one of the other two diodes
conducts for the negative voltage that is applied from the bottom winding due to
the forward bias for that diode. In this circuit due to positive half cycle D1 & D2
will conduct to give 0.8V pulsating DC. The DC output has a ripple frequency of
100Hz. Since each alteration produces a resulting output pulse, frequency = 2 x 50
Hz. The output obtained is not a pure DC and therefore filtration has to be done.
The DC voltage appearing across the output terminals of the bridge rectifier
will be somewhat less than 90% of the applied rms value. Normally one alteration
of the input voltage will reverse the polarities. Opposite ends of the transformer
will therefore always be 180 degree out of phase with each other. For a positive
cycle, two diodes are connected to the positive voltage at the top winding.
FILTERING CIRCUIT:
Filter circuits which is usually capacitor acting as a surge arrester always
follow the rectifier unit. This capacitor is also called as a decoupling capacitor or a
bypassing capacitor, is used not only to ‘short’ the ripple with frequency of 120Hz
to ground but also to leave the frequency of the DC to appear at the output. A load
resistor R1 is connected so that a reference to the ground is maintained.
26. These miniature RF modules provide a cost effective high performance FM
radio data link, as either 315, 433.92 or 868 MHz. Manufactured using later
trimmed thick film creaming hybrid the modules exhibits extremely stable
electronic characteristics over an industrial temperature range. These are no
adjustable components and ensure very reliable operation over time.
This transmitter and receiver pairs enables the simple implementation of a
data link at distances up to 5 meters in building and 25 meters open ground. These
transmitter and receiver modules are optimized for wireless transmission of
encoded data packets. To reduce development time and ensure reliability and
27. security chips from the RF solutions range encryption IC’s can be used to encode
and decode the data.
These modules will suit one to one and multi node wireless links in
applications including car and building security, inventory tracking, remote
industrial process monitoring and computer networking. Because of their small
size and low power requirements, both modules are ideal for use in portable,
battery-powered applications such as hand-held terminals.

operation where a 230V AC appears as 15V AC across the secondary winding.
Apart from stepping down voltages, it gives isolation between the power source
and power supply circuitries.
RECTIFIER UNIT:
In the power supply unit, rectification is normally achieved using a solid
state diode. Diode has the property that will let the electron flow easily in one
direction at proper biasing condition. As AC is applied to the diode, electrons only
flow when the anode and cathode is negative. Reversing the polarity of voltage
will not permit electron flow. A commonly used circuit for supplying large
amounts of DCpower is the bridge rectifier. A bridge rectifier of four diodes (4 x
IN4007) are used to achieve full wave rectification. Two diodes will conduct
33. during the negative cycle and the other two will conduct during the positive half
cycle, and only one diode conducts. At the same time one of the other two diodes
conducts for the negative voltage that is applied from the bottom winding due to
the forward bias for that diode. In this circuit due to positive half cycle D1 & D2
will conduct to give 0.8V pulsating DC. The DC output has a ripple frequency of
100Hz. Since each alteration produces a resulting output pulse, frequency = 2 x 50
Hz. The output obtained is not a pure DC and therefore filtration has to be done.
The DC voltage appearing across the output terminals of the bridge rectifier
will be somewhat less than 90% of the applied rms value. Normally one alteration
of the input voltage will reverse the polarities. Opposite ends of the transformer
will therefore always be 180 degree out of phase with each other. For a positive
cycle, two diodes are connected to the positive voltage at the top winding.
FILTERING CIRCUIT:
Filter circuits which is usually capacitor acting as a surge arrester always
follow the rectifier unit. This capacitor is also called as a decoupling capacitor or a
bypassing capacitor, is used not only to ‘short’ the ripple with frequency of 120Hz
to ground but also to leave the frequency of the DC to appear at the output. A load
resistor R1 is connected so that a reference to the ground is maintained. C1, R1 is
for bypassing ripples. C2, R2 is used as a low pass filter, i.e. it passes only low
34. frequency signals and bypasses high frequency signals. The load resistor should be
1% to 2.5% of the load.
1000f/25V : for the reduction of ripples from the pulsating
10f/25V : for maintaining the stability of the voltage at the load side.
0.1f : for bypassing the high frequency disturbances

35. VOLTAGE REGULATOR:
The voltage regulators play an important role in any power supply unit. The
primary purpose of a regulator is to aid the rectifier and filter circuit in providing a
constant DC voltage to the device. Power supplies without regulators have an
inherent problem of changing DC voltage values due to variations in the load or
due to fluctuations in the AC linear voltage. With a regulator connected to the DC
output, the voltage can be maintained within a close tolerant region of the desired
output. IC7812 and 7912 is used in this project for providing +12V and 12V DC
supply.
36. 5 TO 12 V DC DRIVE CARD
Here we have to drive the 12V DC load(motor ). The 5V signal
from the PIC 16F870 micro-controller is fed into the input of interface
circuit. SL100 transistor is used here for high speed switching purpose
and IRF 540N MOSFET is connected to the motor to handle the larger
current drawn by the motor coil.
38. DETAILS OF HYDRAULIC JACK;
HYDRAULIC JACK
A Hydraulic Jack or for that matter any device using Hydraulic Power in its
simplest possible shape consists of five fundamental components.
A. The Hydraulic Reservoir storing the Hydraulic Oil (Oil is used as the
medium to transmit force and motion-such fluids are called Hydraulic Oils)
should be thoroughly clean, whether integrally built-in or used as a separate
tank.
B. Pump, either of the integral or the remote control type, comprises of highly
precision engineered pump plunger, cylinder, suction and delivery valves,
safety valves with conical or steel balls matched with micron tolerances.
Very often O Rings and special seals are used, made from specially treated
leather or synthetic nitrile rubber or Teflon or other modern substitutes for
greater resistance to wear and sealing ower.
39. It is imperative that these must function at peak efficiency by regular
cleaning and flushing of foreign particles which enter into the hydraulic
system and may clog the delicate valves, damage the seals and affect the
functioning of other elements in the hydraulic circuit.
40. C. A pump by itself would be useless without a system of VALVES to govern
the flow of hydraulic oil to perform the desired function.
D. The transmission of hydraulic oil from the reservoir by the pump through the
valves to Ram & Cylinder which converts the hydraulic pressure into a
mechanical force is by means of a Hydraulic Circuit which is nothing but a
network of passages in hydraulic systems. These passages are formed with
the help of Steel Tubes, Flexible Hydraulic Hoses or through internal holes
or cavities in metal blocks. It is of the utmost importance that the circuit is
always leak proof as well as free from obstacles. Each joint or coupling
must be securely tightened or replaced forthwith. No air lock or foreign
particles should be allowed to interrupt or block the free flow of hydraulic
oil.
E. All hydraulic cylinders consists of two basic elements – the outer housing is
called the Cylinder body and the inner sliding elements is called the Ram
(or piston or plunger) which actually converts the hydraulic pressure into
mechanical force and transmits to the desired point for performing the
41. function. The movement of Ram is always in line with cylinder under
pressure.
Hydraulic Oil is pumped into the cylinder and as more and more oil is forced
into the cylinder pressure builds up and when enough oil is forced into the
cylinder the resultant pressure will cause the ram, plunger or piston to move
and consequently lift, press, push, pull or bend any object any object as the
case may be.
The Ram and Cylinder are also precision engineered and mostly fitted with
high quality seals which give it the necessary compression holding capacity
and prevent leakages.
The five fundamental components already illustrated and described
combined together perform the specified job by a synchronous follow
through of their individual functions.
1. The release valve is closed tightly to ensure flow of oil from the pump to the
cylinder only.
42. 2. As soon as the pump is operated oil is sucked in from the reservoir. As the
Pump Plunger is raised up oil passes from the reservoir into the pump
cylinder with the Suction Valve opening up to allow oil from reservoir to
enter into pump cylinder.
3. When the Pump Plunger is pressed down the Delivery Valve opens up to
allow the passage of oil from the pump into the cylinder, at the same time
the suction valve automatically closes to prevent oil returning to the
reservoir.
4. By repeating the above two operations successively more and more oil is
pumped into the cylinder resulting in the generation of pressure by the action
of the load being lifted.
5. When the load is desired to be lowered the pressure within the cylinder is
released by operating the Release Valve. The oil flows back into the
reservoir shown in the diagram in page 1.
6. Due to neglect or other causes pressure within the system may continue to
increase beyond the predetermined safe working limit. To prevent damage to
43. the system a safety relief valve is located between the cylinder and the
reservoir excessive pressure by the opening up of the safety valve and
discharge of oil into the reservoir (very often the safety overload preventive
relief valve is located in between the reservoir and the pump – the pump
automatically cuts off without delivery of oil to the cylinder due to
generation of excessive pressure within the pump).
The simple diagram shown in page 1 shall help to understand the working of
the hydraulic system in a more graphic manner.

50. BASIC SAFETY RULES FOR HYDRAULIC JACKS;
The nature of lifting operation should determine the choice of jacking equipment-
integral or remote control pump type jacks. Capacity and the hydraulic lifting
stroke are vital aspects to be carefully determined before selection.
Lifting any load calls for precise and safe jacking points. Jack should be centrally
loaded eccentric loading causes dangerous accidents and damages beyond repair.
The world over prudent safety minded operators observe the flowing basic safety
rules :
A. To overpower the load, whether one or a dozen cylinders are used to lift the
load, the cylinder lifting capacity should be two times the weight of the load.
This allows for a reduction in the oil pressure, prevents strain and possible
break-down of the cylinder.
51. B. To balance the load, for large, heavy and uneven loads, it is recommended
dividing the load evenly between a number of cylinders. These cylinders
should be placed beneath the load at points providing the best support, balance
and stability. For example, to lift a 200-tonns load, the necessary 400-tonnes
capacity could be handled by four 100-tonnes cylinders.
C. Never raise the hydraulic ram beyond the specified stroke (lift).
D. Never drop (shock) load on the hydraulic ram.
E. Never go under a load supported by hydraulic ram only.
F. Never extend the hydraulic ram by means other than the pump.
G. Never use hydraulic equipment with observed leakages.
H. Use safety lock nut type jacks for supporting load on jack for long periods.
I. Use steel plates or heavy wooden sleepers where ground surface is soft and
yielding
52. J. Do not disturb the factory preset internal safety valve provided for preventing
overloading.
K. Do not load more than 50% of the rated head capacity on the toe (claw) of toe
lifting jacks.
Positioning the Jack
Jack should be centrally loaded, jack base and upper jacking point must be in level.
Raising the Jack
Turn the release valve in clockwise direction till tight, use end of slotted operating
handles. Start pumping with a regular handle movement. Make only few fast and
rapid download delivery strokes, Jack handle slightly downward, in case the
delivery does not close instantly. Check that the saddles rests firmly against the
Jacking point.
Lowering the Jack
Turn the release valve SLOWLY anticlockwise.
Jack Storage
53. Retract ram completely, close oil filler, keep the Jack away in a safe clean place.
Caution
Do not use the Jack beyond rated capacity and lift mentioned on the name plate.
Making Jack ready for use
VANJAX Hydraulic Jacks are supplied ready for use. Unlock the release valve
half a turn and operate the pump few times to flush the hydraulic unit free from
airlocking.
54. DO’S AND DON’TS
Do’s Don’ts
Air venting is an important
precaution for the successful
performance of any hydraulic jack
or hydraulically operated device,
equipment or system.
Under no circumstances the
equipment should be used beyond
rated capacity or rated stroke. It is
in the interest of the user and for the
protection of his costly equipment to
ensure correct selection of the
capacity and restricting the stroke
within the rated stroke length.
All couplings and other fasteners
should be properly tightened.
Do not forcibly hammer fit
accessories if falling short by a
fraction of the required length or
spread. Use the next higher size
equipment. Abuse of accessories
and attachments are hazardous both
for the equipment and the personnel.
55. At all times the entire equipments
should be kept free from dust
through regular systematic cleaning.
Do not expose the equipment to
areas of excessive heat or where dirt,
dust and heavily laden fumes /
smoke are prevalent. If the
equipment is used in such areas it is
absolutely essential to service it at
once.
Check oil level each time before use. Do not refill without a reliable
strainer
Every time the hydraulic hose is
attached to the pump and the ram
cylinder assembly unit, it should be
thoroughly flushed.
Do not use brake fluid as refill.
Release valve to be properly
tightened by turning it in clock-wise
direction when applying load. For
releasing pressure open release
valve gradually by turning it in anti-
clockwise direction.
Do not hammer to open guide nuts.
Open by guide nut spanner.
56. The equipment must be centrally
loaded. The pressure screw in a
hydraulic puller should be
absolutely perpendicular to the axis
of the load.
Do not apply extra force to close the
release valve. Normal hand
pressure is enough.
As refill we recommend IOC Code
No. Servo System 32 and 46, HPC
Hydrol 0232 or any other
equivalent.
Do not use fluffy cloth or cotton
waste for cleaning cylinder ram,
valve, pump and oil tank.

JOB PREPARATION
Before welding, remove any bend in the L angle with the sludge hammer on
the anvil block. Then it is cut to the required length with the hacksaw blade and
fabricated to required dimensional shape with arc welding.
FINISHING OPERATION BEFORE PAINTING
After welding, any slag on the welded area is removed with the chipping
hammer and cleaned with the metal wire brush. Then all the surfaces are rubbed
with the emery sheet.
Metal primer is applied on the surfaces with the brush. After drying the metal
primer, the second coating is applied with the paint.
