“…Before starting the lifting hydraulic motor, the lift control handle is set to zero and the cylinder block of the controlled pump is in neutral position at which the pump feed is zero [5,6]. During the start-up period, the operator of the sinking hoisting plant re-moves the control handle in one direction or the other (depending on the bar-ban rotation direction) and gradually withdraws the cylinder block of the regulated pump from the neutral position, thus ensuring a smooth supply of hydraulic fluid to the lifting hydraulic motor.…”

“…1. Start of the lifting hydraulic motor is carried out with the help of the handle of the hoisting machine or the monitoring electrohydromechanical control system [7]. The cylinder block of the regulated pump is moved from the neutral position and the pump supplies the working fluid to the lifting hydraulic motor.…”

“…Electro-hydraulic motors of mobile sinking hoisting plants operate under conditions that differ significantly from the operating conditions of stationary lifting motors. These differences consist in the fact that hydroelectric drives are used in mobile sinking hoisting plants with continuously variable lifting heights, with different lifting capacities at different lifting speeds [1].…”

The article presents the results of the control system development for the electro hydraulic drive of a mobile sinking hoisting plant. Increasing the technical performance of mobile sinking hoisting plants is possible by increasing their productivity, reducing their massiveness and increasing the durability of tractional organs and a number of units and parts of lifting machines. However, the increase in productivity, in its turn, causes the need to increase the suspended load on the traction organs, which causes a significant increase of the dynamic loads in the elastic elements in the transient operation modes of the hoisting plant. One of the ways to reduce constantly acting dynamic loads of vibration character is the use of a gearless hydraulic drive with damping properties. But, nevertheless, the hydraulic drive possibilities are limited for large vibration amplitudes of dynamic forces. The damping properties of the hydraulic drive can be increased by using control system, which allows realizing effective control of the electro hydraulic drive of the hoisting plant.
