Abstract: The purpose of the work – to find out the features of throttle adjustment of the speed of movement of the piston of the hydraulic system of big capacity. The experimental research has been carried out with the above described device. In the hydraulic cylinder design changes have been executed, the sizes and throttle place by means of the theoretical throttle characteristic ADR = f(h) are changed. For reduction of the turn time of the working platform it was necessary to increase pressure in the hydraulic systems from 60 to 70 bar. Pressure increase has allowed the piston to increase the speed of movement. The time of turn of the working platform has decreased till 1.31 seconds. The piston pressure in the braking chamber is equal in the last phase of work to 48 bar, it tells about prevention of blowing the piston about the hydraulic cylinder
