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.
