Linear winch type BI 300

Product description

BI 300 linear winch 300 mTon capacity


The BI 300 linear winch is build to specification of Bezemer. This winch is particular suitable to work on offshore platforms to pull in anchor chains and/or SCR’s. Although the capacity of the winch is high the dimensions are small and can be placed on most platforms and spars.


The BI 300 linear winch can either work with a diesel hydraulic power unit or electric hydraulic power unit, there is also a possibility to have 2 units next to each other synchronized from one HPU.



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. One of the grippers moves back and forth (extend and retract) through the action of two hydraulic main cylinders,the other gripper is stationary in the winch frame.


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 the movable 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.


Wire rope payout can also be accomplished manually or automatically. Since the wedges holding the load cannot be opened, control of the load is always maintained.


The design of an intermittent linear winch allows it to build a compact machine which is suitable to work on either offshore platforms with limited or in area’s with limited space and/or crane capacity, this type is less suitable for long beach pulls.
