1. Dumpers and dump trucks are vehicles used to transport bulk materials. Dumpers have the load skip in front of the driver that tips to dump the load, while dump trucks have the cab in front of the load.
2. Modern dumpers can carry payloads of up to 10 tons and usually steer by articulating in the middle. They are powered by diesel engines and use hydraulics for tipping, steering, and body lifting. Larger dump trucks ranging from 10-400 tons are used for construction and mining to transport materials over long distances.
3. There are different types of dump trucks including rear dump, bottom dump, articulated, and tipper trucks which are suited to different haul

Three Axis Pneumatic Modern Trailer By Using Single Cylinderpaperpublications3
Abstract: This project work titled “THREE AXIS PNEUMATIC MODERN TRAILER” has been conceived having studied the difficulty in unloading the materials. Our survey in the regard in several automobile garages, revealed the facts that mostly some difficult methods were adopted in unloading the materials from the trailer. The trailer will unload the material in only one single direction. It is difficult to unload the materials in small compact streets and small roads. In our project these are rectified to unload the trailer in all three sides very easily. Now the project has mainly concentrated on this difficulty, and hence a suitable arrangement has been designed. Such that the vehicles can be unloaded from the trailer in three axes without application of any impact force. By pressing the Direction control valve activated. The compressed air is goes to the pneumatic cylinder through valve. The ram of the pneumatic cylinder acts as a lifting the trailer cabin. The automobile engine drive is coupled to the compressor engine, so that it stores the compressed air when the vehicle running. This compressed air is used to activate the pneumatic cylinder, when the valve is activated.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

2. 1.2.1. DUMPERS- INTRODUCTION
A dumper is a vehicle designed for carrying bulk material, often on
building sites.
A dumper is usually an open 4-wheeled vehicle with the load skip
in front of the driver.
The skip in a dumper can tip to dump the load; this is where the name
"dumper" comes from.
Dumpers are distinguished from dump trucks/ dumper trucks by
configuration:
A Dump truck has its cab in front of the load.
A Dump truck is a tyre mounted vehicle with a body mounted on
chassis and an operator cabin.

3. 1.2.1. DUMPERS –INTRODUCTION- PAY LOAD
It is the capacity of the equipment for which the customer is paying i.e. we
say a truck has payload capacity of 10 ton.
This means when we purchase this truck
we expect it to carry 10 ton of material and
we are ready to pay for this 10 ton truck.

4. 1.2.1. DUMPERS-INTRODUCTIONWHAT IS ON ROAD & OFF ROAD?
On road means when a vehicle is running on public road and is
bound to follow the common traffic rules
with other vehicles plying on the road.
Off road means a vehicle is running on a
non public road, i.e. private road.
This private road may be
inside a mine or in
a construction site.
Moreover the road width may be
non standard type and may be
designed exclusively to suit the
vehicles plying on it.
Also the traffic rules may be
different in off roads in
a particular mine.
5. 1.2.1.1. DUMPERS
Track type
Dumpers are normally diesel powered.
A towing eye is fitted for secondary use as
a site tractor.
Carrying capacity (flat level ground): 500 kg
Dumpers with rubber tracks are used in
special circumstances and are popular in some countries.
Early dumpers had a payload of about a ton and were
2-wheel drive, driving on the front axle and steered at the back
wheels.
The single cylinder diesel engine (sometimes made by Lister)
was started by hand cranking.
The steering wheel turned the back wheels, not front.
Having neither electrics nor hydraulics there was
not much to go wrong.
The skip was secured by a catch by the driver's feet.
When the catch is released, the skip tips under
the weight of its contents at pivot points below,
and after being emptied is raised by hand.

7. 1.2.1.1. DUMPERS-HOW DOES A DUMPER FUNCTIONS?
In primitive models the body had to be lifted manually but
nowadays all dumpers have hydraulic body lifting mechanism.
All dumpers have an engine as a prime mover.
Then there will be transmission system, differential and
final drive.
There will also be a hydraulic system for body lifting function
and steering function.
What is the power flow system in a dumper?
The prime mover is an engine.
Then there will be a
clutch or torque converter
from which power flows
to gear box or transmission.
The output of transmission
goes to differential through a
propeller shaft.
Then there will be hub or final drive on which
tyres will be mounted.
8. 1.2.1.1. DUMPERS-WHAT ARE THE BASIC SYSTEMS?
A dumper has the following systems Power transmission system – consisting of Engine, torque
converter, transmission, propel shaft, differential and final drive.
Hydraulic system – consisting of Hydraulic pumps, control valves,
Hydraulic cylinders (for body lifting and steering), Hydraulic tank and
Steering orbitrol.
Pneumatic system – consisting of air compressor, air tank, auto
drain valve, un loader valve, brake treadle valve (for brake
actuation) and accelerator pedal (in case of pneumatic cylinder for
engine acceleration).
Electrical system – consisting of battery, circuit breakers or fuses,
solenoid coils, resistance, relays, sensors, meters/ gauges, starter,
alternator, ammeter, switches, bulbs, head light, turning indicators,
wiper, fan, horn, reverse horn, brake light.
Brake system –. The service brake is air over hydraulic, shoe type
and the brakes are applied on all the four wheels. This brake is
applied for stopping the machine when in motion.

1.2.1.1. DUMPERS- MODERN DUMPERS
Modern dumpers have payloads of up to 10 tonnes
and usually steer by articulating at the
middle of the chassis (pivot steering).
They have multi-cylinder diesel engines, some turbocharged,
electric start and hydraulics for tipping and steering and are
more expensive to make and operate.
An A-frame known as a ROPS (Roll-Over Protection) frame,
may be fitted over the seat to protect the driver if the dumper rolls
over.
Some dumpers have FOPS (Falling Object Protection) as well.
Lifting skips are available for discharging above ground level.
In the 1990s dumpers with swivel skips,
which could be rotated to tip sideways,
became popular, especially for working in
narrow sites such as road works.
Dumpers are the most common cause

11. 1.2.1.2. DUMP TRUCKS/ DUMPER TRUCKS
A dump truck has its cab in front of the load.
A dump truck (or, UK, dumper truck) is a
truck used for transporting loose material
(such as sand, gravel, or dirt) for construction.
A typical dump truck is equipped with
a hydraulically operated open-box bed hinged at the rear,
the front of which can be lifted to allow the
contents to be deposited on the ground
construction plant only
behind the truck at the site of delivery.
In the UK and Australia
the term applies to
off-road construction plant only, and
the road vehicle is known as a tipper,
tipper lorry (UK) or
tip truck (AU)
dump truck / dumper truck
12. 1.2.1.2. DUMP TRUCKS / DUMPER TRUCKS
The body can be lifted or opened hydraulically for
unloading of the material inside the body.
This is a common term used for a wide variety of
configuration of trucks used for
road vehicle
transporting material.
The payload capacity ranges from
10 ton trucks used mainly for
construction purposes and
small private mines
tipper tipper lorry (UK) or
to 400 ton trucks which are
tip truck (AU)
mainly off road vehicles and are
used exclusively in mines for carrying of

15. 1.2.1.2. DUMP TRUCKS/ DUMPER TRUCKS-TYPES
a) Dump Trucks
Dump Trucks are exclusively meant for hauling various materials
to a large distance.
b) Rear Dump Trucks
As the name suggests, the dumping of the material (load) is done
over the rear by tilting the body using hydraulic cylinders.
c) Bottom Dump Trucks
If trucks are used to haul materials, such as sand, gravel,
reasonably dry earth, coal etc. which flow easily, the use of
bottom dump trucks will reduce time.
d) Articulated Dump Trucks
These kind of trucks facilitate better maneuverability .
e) Tipping Trucks
Tipping trucks are smaller version of dump trucks.
