Design of hoisting mechanism and hydraulic

system for truck crane

ABSTRACT

The design introduce the principle of the Automobile Hydraulic cranes, and details calculation of the entire process on the lifting body design , including lifting the principle and parameters, structural design. The design of the truck crane from the use of quantitative motor and institutions, reducers, brakes, couplings and reel components. According to the hydraulic system of technical indicators of the overall system design, its functions and working principles for analysis, determined the loop system and the basic structure of the main components, according to the agency by the performance parameters and performance parameters of hydraulic components the choice of terms, for the crane achieve the requirements.

Key words:Truck crane；Lifting mechanism；
