Linear winch type KTC 500

Product description

KTC 500 Linear winch 500 mTon capacity


Specially designed and manufactured for work on offshore platform this linear winch is a state of the art unit. The linear winch is designed in such a way that it can be divided in four (4) sections, with a maximum weight of 20 Mton, to meet the, often low, capacity of platform cranes. Each section of the linear winch can be lifted without a cradle, since each part is separate certified according to DNV 2.7-1.


Furthermore the unit can be used on live platforms and refineries, since all components of winch and power unit are explosion proof. Also the design is according to Norsok Z-015.


The above makes it possible to operate in Zone 2, IIA, T3. The machine proved its capabilities on 2 offshore platforms, "Troll A" and "Gullfaks C" both operated and owned by Statoil.


  


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.
