ABSTRACT
Dedicated dump truck is equipped with a hydraulic lifting mechanism, able to train or to car tilted at an angle, remove the goods on their own or rely on gravity to push the level of discharge of the Special Purpose Vehicle. Firstly, the design of the truck structure, characteristics and development status at home and abroad to do the relevant overview. Outlines the basic structure of dump truck and forms of work, but also introduces the truck's overall argument. In the article analyzes the development of our country and the dump truck dump truck design features, introduced the dump truck classification and the advantages and disadvantages of different forms of lifting. The lifting mechanism on the truck to do a systematic analysis and selection of the calculation, introduced the hydraulic control system and the lift system components, the work on the dump truck different angle of the force and the largest selection of lift were calculated and analyzed. Then choose from the dump truck chassis, the choice of conversion calculation subframe is analyzed. Finally, the outer profile of the size of the dump truck, track and wheelbase dimensions, front overhang, rear overhang and the quality of vehicle loading, curb weight, the total quality of the relevant calculation and design.
