This Presentation consists of details about the various Hoisting and Transporting Equipments In details.The concepts has been explained thoroughly with the help of Diagrams and various pictures related to the topics.
2. THE HOISTNG IS THE LIFTING OF THE MATERIAL
AGAINST GRAVITY AND MAYBE DONE WITH A
WIDE RANGE OF EQUIPMENTS FROM THE SMALL
HAND OPERATED SIMPLE SCREW OR
HYDRAULIC-JACK TO MODERN HIGH POWERED
CRANES AND ELEVATORS.
3. ASSEMBLY:-MOVING PRODUCTS THROUGH PRODUCTION
PROCESSES
POSITIONING:-SECURING A COMPONENT FOR
ADDITIONAL WORK
TRANSPORTATION:-LOADING FINISHED PRODUCTS ONTO
OPEN TRAILERS OR RAILCARS
STAGING:-HOLDING WORK IN PROGRESS FOR
ADDITIONAL PRODUCTION PROCESS
STORAGE:-TRANSPORTING HEAVY ITEMS TO AND FROM
STORAGE AREAS
WAREHOUSING:-MOVING LARGE, HEAVY PRODUCTS TO
AND FROM DOCKS
5. The chain hoists are the popular mechanism for lifting
loads upto tones.
The system consists of two sets of chains, namely the hand
and load chain.
The hand chains are particularly useful for the isolated
location , where an electric motor or other types of
mechanical equipments are not available.
The pull applied through the hand chain is transmitted to
the load chain with a multiplication factor of over 20.
The load to be lifted is held by a load hook while another
hook(called support hook) at the top, support the
mechanism.
6.
7. A pulley is a wheel on an axle or shaft that is designed to support
movement and change of direction of a cable or belt along its
circumference. Pulleys are used in a variety of ways to lift loads, apply
forces, and to transmit power. In nautical contexts, the assembly of
wheel, axle, and supporting shell is referred to as a "block.“
A pulley may also be called a sheave or drum and may have a
groove between two flanges around its circumference. The drive
element of a pulley system can be a rope, cable, belt, or chain
that runs over the pulley inside the GROOVE
The pulley and sheave blocks suitable for lifting rough surface
and heavy loads.
For this purpose the chains and wire ropes are used.
8.
9. A CRANE IS A TYPE OF MACHINE, GENERALLY EQUIPPED WITH A
HOIST ROPE OR CHAIN, AND SHEAVES, THAT CAN BE USED
BOTH TO LIFT AND LOWER THE MATERIALS AND TO MOVE
THEM HORIZONTALLY. IT IS MAINLY USED FOR LIFTING HEAVY
THINGS AND TRANSPORTING THEM TO OTHER PLACES.
11. A MOBILE CRANE IS A CABLE-CONTROLLED CRANE
MOUNTED ON CRAWLERS OR RIBBED-TIRED CARRIES OR
A HYDRAULIC-POWERED CRANE WITH A TELESCOPIC
BOOM MOUNTED ON TRUCK-TYPE CARRIERS OR AS SELF-
PROPELLED MODELS
12. TRUCK-MOUNTED CRANE IS A SELF-PROPELLED LOADING-
UNLOADING MACHINE MOUNTED ON A TRUCK
BODY,WITH A WORKING SECTION CONSISTING OF A
ROTATING CANTILEVERED BOOM.
THESE CRANES ARE SUPPORTED (OUTRIGGERS) WHILE
LIFTING CARGO, IN ORDER TO INCREASE THEIR STABILITY.
13. These are the crane of swing job type an are mounted
on high steel towers.
The height of tower maybe 25 to 30 m and these
cranes are found to be suitable in the construction of
tall buildings in congested areas.
The ground area required for such cranes is very small.
14.
15.
16. This crane is a combination of stationary and mobile unit. This
combines the advantages of log boom of derrick crane and
mobility of the mobile crane.
The rotating structure has an outer Framework.
The boom is attached to the front end of this framework. The
counter weight is provided at the rear end. On the diagonally
opposite corners of the base, two separate motors are provided,
which give movement to the central shaft.
17. AN OVERHEAD CRANE, COMMONLY CALLED A BRIDGE
CRANE, IS A TYPE OF CRANE FOUND IN INDUSTRIAL
ENVIRONMENTS. AN OVERHEAD CRANE CONSISTS OF
PARALLEL RUNWAYS WITH A TRAVELLING BRIDGE
SPANNING THE GAP.
A HOIST, THE LIFTING COMPONENT OF A CRANE, TRAVLES
ALONG A BRIDGE.
18. A LOADER CRANE (ALSO KNOWN AS A KNUCKLE BOOM
CRANE OR ARTICULATING CRANE) IS AN ELECTRICALLY
POWERED ARTICULATED ARM FITTED TO A TRUCK AND IS
USED FOR LOADING/UNLOADINGTHE VEHICLE CARGO.
THE NUMBERS JOINTED SECTIONS CAN BE FOLDED INTO
A SMALL SPACE WHEN THE CRANE IS NOT IN USE.
UNLIKE MOST CRANES, THE OPERATER MUST MOVE
AROUND THE VEHICLE TO BE ABLE TO VIEW HIS
LOAD,HENCE MODERN CRANES MAY BE FITTED WITH A
PORTABLE CABLED-LINKED CONTROL SYSTEM TO
SUPPLEMENT THE CRANE-MOUNTED HYDRAULIC
CONTROL LEVERS.
19.
20. The derrick cranes are of two types, namely:
Guy derrick and
Stiff leg derrick
The guy derrick consists of a vertical mast . This mast is supported by
the number of guys and can revolve through .ْ 360
While revolving, the radius of revolution should be such that the
revolving structure is not obstructed by the guy wires.
This derrick can be constructed upto 200 tonnes capacity .
In stiff leg type derricks, the guy wires are replaced by trussed
structure.
This type of derricks are suitable for loads from 10 to 50 tonnes by a
diesel engine or by an electric motor.
21.
22. A winch is a mechanism in the shape of a cylinder or
drum, over which rope or chain is wound.
If a winch is used only for raising and lowering, it is
sometimes referred to as hoist.
The winches are of two types :-
hand winches
power winches
23. A HAND WINCH OR MANUAL WINCH IS A PULLING OR
LIFTING DEVICE WITH A ROPE, STRAO, CABLE, OR CHAIN
WOUND AROUND A ROTATING DRUM THAT IS OPERATED
BY A HAND CRANE.HAND WINCHES ARE MORE OFTEN
RATCHET DEVICES OR USE SPUR OR WORM GEARS TO
OPERATE THE DRUM.
24. A POWER WINCH IS A PULLING OR LIFTING DEVICE WITH
A CABLE WOUND AROUND A ROTATING DRUM, AND
OPERATED BY A MOTOR OR OTHER POWER
SOURCE.PULLING WINCHES MOVE LOADS
HORIZONTALLY.
25. Disadvantage of chain hoist is slow lift in pace and limited places.
Hydraulic engine hoist can take a lot of space in garage.
Electric hoist are not good with heavier loads.
electric hoist is that they need a special place to be installed.
electric hoist will be static and cannot be moved around (without
special installations), so you will always have to place a reparable car in
the same place.
Electric hoist needs to be placed above the ground. This usually means
mounting it to ceiling or building a special scaffolding to install an
electric hoist.
Another disadvantage of electric hoist is that it needs an electric
power source in order to work. Hydraulic or chain engine hoists
need to be operated manually, while electric hoist has got an
electrical motor that works with an electrical power
26. The lifting of load is also very slow in chain hoist.
This lifting process in chain hoist is slower than
electric hoists or hydraulic hoists.
The cranes used as hoisting equipments are expensive.
electric hoist is fast and convenient tool to use for
lifting moderately heavy loads, but becomes much
more expensive, if you need to lift loads heavier than
225 kg (500 lb).
27. TRANSPORTING EQUIPMENT IS USED TO MOVE
THE MATERIAL FROM ONE LOCATION TO
ANOTHER (eg. BETWEEN WORKPLACES,
BETWEEN A LOADING DOCK, AND A STORAGE
AREA etc.) WITHIN A FACILITY OR AT A SITE.
TYPES:-
BELT CONVEYORS
ROPEWAYS
TRUCKS
WAGONS
28. A BELT CONVEYOR SYSYTEM CONSISTS OF TWO
OR MORE PULLEYS, WITH AN ENDLESS LOOP OF
CARRYING MEDIUM-THE CONVEYOR BELT THAT
ROTATES ABOUT THEM.
ONE OR BOTH OF THE PULLEYS ARE POWERED,
MOVING THE BELT OR THE MATERIAL ON THE
BELT FORWARD
THE POWERED PULLEY IS CALLED THE DRIVE
PULLEY WHILE THE UNPOWERED PULLEY IS
CALLED IDLER PULLEY.
29.
30. Conveyor belts are widely used in mineral industry.
Undergo mine transport, open cast mine transport.
Longer distances can be covered more economically
than any other transportation system.
Minimum labour is required for the operation and
maintenance of belt conveyor system.
Many other functions can be performed with basic
conveying like weighing, sorting, picking, sampling,
bending.
31. The angular velocity ratio is not necessarily constant or
equal to the ratio of pulley diameters, because of belt
slip and stretch.
Heat buildup occurs. Speed is limited to usually 7000
feet per minutes(35 meters per seconds). Power
transmission is limited to 370 killowatts.
Some adjustment of centre distance or use of an idler
pulley is necessary for wear and stretch compensation.
A mean of disassembly must be provided to install
endless belts.
32. A truck or lorry is a motor vehicle designed to
transport cargo.
Trucks have high mobility and can haul various
types of material.
Trucks vary greatly in size, power, and
configuration.
33. Dump trucks are open vehicles which are capable of
carrying and dumping earth.
It is also used to dump aggregates and other loose
material to construction sites.
Dump trucks are in many sizes with pay loads
ranging upto more then 300 tonnes are available.
This may have 2 or 3 axle.
Dump trucks are of 2 types
i) On Highway Dump trucks
Ii) Off Highway Dump trucks
34. ON HIGH-WAY DUMP TRUCKS
•These on highway dump trucks are
generally classified by the volumetric
or tonnage payload capacity.
•Generally Dump trucks of capacities
ranging between 3-25 cu.m are
commonly used with speed upto 80
kmph.
•Body of dump trucks is heavy duty
type.
•In on highway dump trucks a tailgate
is provided at rear.
35.
36. Off highway Dump trucks do not
have tail-gate.
The body is of high tensile steel.
Top speed of highway dump
trucks is 30-40 kmph.
Main types of Highway Dump
Trucks are :
• Rear Dump trucks
• Bottom Dump trucks
• Side Dump trucks
OFF HIGH-WAY DUMP TRUCKS
37. For
transportation of
rocks and other
heavy
materials under
adverse road
conditions,
the rear dump
trucks are most
suitable.
REAR DUMP TRUCKS
38. These trucks
are suitable for
long hauls
of easy
flowing
materials like
sand,
gravels, dry
earth.
BOTTOM DUMP TRUCKS
39. These Dump trucks
are most
suitable when
dumping is
required to be done
in along
narrow length or
on one or
both sides of road.
These require very
less time to
dump it’s material.
SIDE DUMP TRUCKS
40. A TRANSPORT SYSTEM FOR MATERIALS OR PEOPLE, USED
ESPECIALLY IN MINES OR MOUNTAINOUS AREAS, IN
WHICH CARRIERS ARE SUSPENDED FROM MOVING
CABLES POWERED BY A MOTOR.
IT IS A VERY USEFUL METHOD OF TRANSPORTATION FOR
VERY SHORT DISTANCE.
IT COMPRISES A JACKSTAY, SLUNG BETWEEN TWO SHEERS
OR GYUNS, ONE AT EITHER END, FROM WHICH IS
SUSPENDED A BLOCKAND TACKLE, THAT IS FREE TO
TRAVEL ALONG THE ROPE AND HAULED BACK AND
FORTH BY INHAULS.
41.
42. IT IS AN EFFICIENT WAY IN HILLS CROSSING ONE
END TO ANOTHER.
IT IS A POLLUTION FREE.
IT IS A SOLVE TRAFFIC PROBLEM IN CRITICEL
PLACES.
IT IS VERY GOOD SOURCE IN URBAN
TRANSPORTATION.
HELPS IN TRANSPORTATION OF BULKY
MATERIALS.
43. HIGH INITIAL INVESTMENT.
LIMITATION AS THE SIZE AND QUANTITY OF
HAUL.
LIMITED LOAD CARRYING CAPACITY.
44. A vehicle used for transporting goods or for
another specified purpose. It is of various kinds
OF commercial vehicle for the transport of heavy
loads, delivery, etc. and designed to be pulled or
sometimes having its own motor.
They are also called carts, pulleys, etc.
It is sometimes cheaper to transport materials over
a short distance with the help of a hand cart.
45. USED FOR TRANSPORTING GOODS.
USED FOR TRANSPORTING AGRICULTURAL
PRODUCTS.
USED FOR TRANSPORTING SUPPLIES AND
SOMETIMES PEOPLES.
