800 ton linear winch type KTC 800 SP

KTC 800 SP linear winch 800 mton capacity
The KTC 800 is one of the most powerful socket passing linear winches operating in the world. Specially designed by Bezemer and built by Kley France this unit is used for very heavy beach pulls or other projects which require a high pull force on single wire.

This machine can accommodate wire sizes up to 152mm and is capable to pass sockets up to wire size 128mm at full load.

Due to its large capacity also the weight of the machine is quite high, however the winch is built in 2 pieces which can easily be connected and disconnected, given a weight of less than 60 mton.

The power unit is built in two (2) separate skids, to reduce the dimensions and weights.

General description linear winch
The linear winch consists of two grippers mounted in a frame. The wire rope passes through each gripper. Each gripper is capable of holding the wire rope. The grippers move back and forth (extend and retract) through the actions of four hydraulic main cylinders. The grippers are independently controlled and their movement can be sequenced to either pull-in or payout the wire rope.

The holding action is developed by two wedges inside each gripper. If the wedges are contacting the wire rope when a load is applied to the wire rope, the wedges will clamp onto and hold the wire rope. When one gripper is pulling, the wire rope slips through the wedges of the other gripper.

Four hydraulic wedge cylinders control wedge movement. Extending the wedge cylinders closes the wedges. Retracting the wedge cylinders opens the wedges. Each pair of wedge cylinders is hydraulically connected in parallel to assure equal actuating forces.

Wire rope pull-in is accomplished manually or automatically by the control system. In both the manual and automatic mode, the #1 and #2 gripper wedges maintain in contact with the wire rope at all times.
