Design and Fabrication Of Dump Truck Tilting System

Abstract:

With the advancement of the transport technologies, companies are trying to find ways to find simpler and cost effective technologies. In today scenario dump trucks are used to transportation of materials till now they are operating by hydraulic cylinders.The hydraulic cylinders used for the dump truck tilting system are very long so that it can be lifted to a good height. It also requires a cylinder with greater diameter so that is can bear the weight of the materials in the truck. This
requires a large space to house the cylinder and also the cylinder is prone to damages as it has to bear heavy loads.
This not only occupies more space, but also increases the weight of the vehicle, which indirectly affects the fuel economy of the truck. Thus there is a surge to find
possible methods for improving the mechanism of the dump truck hydraulics.This project proposes the idea of using a folding mechanism coupled with pneumatics to tilt the trolley of the dump truck. The system employs the use of a linkage hinged to together and a pneumatic cylinder is attached to the hinge. Thus when the pneumatic cylinder works in the forward direction, the linkages are stretched and when it is made to return, the linkages get folded up.

Introduction

The hydraulic cylinders used for the dump truck tilting system are very long so that it can be lifted to a good height. It also requires a cylinder with greater diameter so that is can bear the weight of the materials in the truck.
This requires a large space to house the cylinder and also the cylinder is prone to damages as it has to bear heavy loads. This not only occupies more space, but also increases the weight of the vehicle, which indirectly affects the fuel economy of the truck. Thus there is a surge to find possible methods for improving the mechanism of the dump truck hydraulics.This project proposes the idea of using a folding mechanism coupled with pneumatics to tilt the trolley of the dump truck.

DESIGN AND FABRICATION OF DUMP TRUCK TILTING SYSTEM

The system employs the use of a linkage hinged to together and a pneumatic cylinder is attached to the hinge. Thus when the pneumatic cylinder works in
the forward direction, the linkages ate stretched and when it is made to return, the linkages get folded up.

Proposed model:
This project proposes the idea of using a folding mechanism coupled with pneumatics to tilt the trolley of the dump truck.A dump truck or trailer for hauling and
dumping dry bulk solids conventionally by gravity and also having the capability of conveying the solids upward to a storage facility. The unit includes a container mounted to a frame on wheels. A hydraulic ram tilts the container for dumping through a rear outlet. A pneumatic conveyor is carried by the frame with an intake at the rear of the container. A gate allows the solids to be dumped conventionally by gravity, or to be blown to a storage facility by the pneumatic conveyor.

Details of Components Used

• Hand Lever solenoid valve Solenoid valve
• Flow control valve
• Hose and connectors
• Linkages
• Tilt-able Trolley
• Frame

Construction:
Our proposed model ―MODIFIED DUMP TRUCK TILTING SYSTEM need so many raw materials which are mentioned in above chapter. For that materials first of all we purchased the raw materials based upon requirement and for that we‘ve planned to how to buy. After bought we cut raw materials in required dimensions in precise manner by using hand wheel cutting machine. After that we‘ve gone for some rough turning and finishing by using lathe and grinding machines.
After that for assembly purpose we went for welding for permanent joint wherever we require and joined with rivets wherever we require rigidly fixed joints. Up to this, mechanical operations and assembly had done the main thing is need to give connections of pneumatic cylinders to the our model at the last time we had given connections to the pneumatic cylinder and solenoid valve, thereafter we joined that pneumatic cylinder to tilting truck to perform it‘s function on tilting truck.

Working principle

The system employs the use of a linkage hinged to together and a pneumatic cylinder is attached to the hinge. Thus when the pneumatic cylinder works in
the forward direction, the linkages at stretched and when it is made to return, the linkages get folded up.Hand lever solenoid valve get the air and passed through the pneumatic cylinder depend upon the hand lever directional changed. The linkages are those that support the trolley against the frame and they are hinged at the center.

Advantage And Application

Advantage:
• Free from wear adjustment.
• Less power consumption
• Less skill technicians is sufficient to operate.
• It gives simplified very operation.
• Installation is simplified very much.
• Less time and more profit.
• Reduced stroke length of cylinder
• Reduced cost in pneumatics
• Simple construction
• Reduced weight of the system.
• Ease of operation

Applications:
• It can be used for dump trucks.
• It can be used in factories for tilting large equipment
