Specification of Forces in Hydraulic Cylinders for Lifting and Transporting Mechanism HR3001

The article deals with dynamic analysis of mechanism HR 3001 used at the lifting and transporting of various types of bodies or loads. It can be placed on the lorry so the manipulator becomes part of it. The goal of the analysis is to investigate the drive forces in hydraulic cylinders which are necessary for the lifting of load with specified mass. The modern methods used computer aid with the special software for analysis processing, which can simulate not only the motion of the mechanism, but they can define the position, velocity, acceleration, forces, moments and other parameters in every moments of time, but verification and mechanics laws understanding are necessary. The results serve for dimensioning of hydraulic cylinders at the designing of mechanism.
