Hydraulic rail jack
ZKH 8t

The ZKP 1000 K lever rail jack (hereinafter referred to as the jack) is a mechanical device designed for manual manipulation – lifting rails during service activities on the railway superstructure, for example when replacing absorption pads under the rail heel, replacing underlays, for manipulating rails during alignment during assembly, etc. The jacks are designed for various types of rails.

The jack consists of a frame into which two support legs, two clamping segments, a hand lever and two connecting plates are bolted, which connect the segments to the lever. The jack is placed above the top of the rail head at the sleeper location. The jack legs are placed on the upper side of the sleeper. By folding the jack lever, the two clamping segments are lowered and opened at the same time.

Flipping the lever of the jack to the other side clamps the segments and lifts them. During lifting, the segments clamp the rail head and secure the rail against falling out.

By different combinations of the holes in the plates, different lifts can be achieved as required. After rotating the legs of the jack, the jack can also be used for wider rail fastening systems to sleepers.
