Hydraulic tensile compensator, Type: HV 4 four-ropes – HV 2 two-ropes

Hydraulic tensile compensator serves for the rope tensile balancing by more-ropes winding machines equipped with a friction disc that are rising by the operation from various ropes prolongation, from their tolerance stiffness or from different diameters of the rope-slots of the friction disc. The winding plant is delivered together with a complete relevant compensator set according to the ropes number with hydraulic interconnection of cylinders, valves, pressure gauge and the hydraulic oil supply bin.

Balancing of the rope tensile consists in the principle of equal pressures in cylinders (given by load), their hydraulic interconnection by the possibility of different strokes of individual cylinders, which answers to different lengths of re-winded ropes. Tensile equalization is enabled until the stroke utilization, then the rope in the thimble must be shortened.

The operation compensator set consists of the same number of cylinders (1) like winding ropes. The cylinder (1) consists of two upper side-frames (2) and two bottom ones (3), equipped on one side with a head with an eye for hinge pins (6, 7) and on the other side with a screwed spherical bearing (4) with a working hydraulic cylinder (5) between them. The individual cylinders (5) are hydraulically interconnected (8), with hoses, screws, distribution cubes, control-valves set, pressure gauge and the hydraulic oil supply bin (9) placed together with the valves and cubes on the carrying console (10).

Safety: The product answers to the requirements of the Public Notices No. 22/1989 Coll. and No. 415/2003 Coll. of ČBÚ (Czech Mining Office Board); the safety of mechanical carrying parts of the compensator is minimum 7-tuple against the type static load.
