1 OPEN WINH For process cranes and high capacities

2 Standard open winch large range from.t to 00T These type of crabs are produced on demand to address special needs such process cranes with special features of capacity, safety, speed or other requirements. It is called Open Winch due to all the elements are manufactured with independent and different sub-assemblies for easy maintenance. 2

WHY AN OPEN WINH? 1.- Brake 2.- Motor.- Gearbox.- Wire rope press roller / wire rope anti-overlapping 5.

Possibility of working with motors of 1,0 rpm., 1,000 rpm., and 7 rpm., Bigger motor sizing. ommercial motors usage to adequate customer standards.

Direct shaft from motor to gearbox to drum with flexible and intermediate assemblies, absorbing the shocks at the time of lifting.

Easy access to the components for easy maintenance.

3 WHY AN OPEN WINH? 1.- Brake 2.- Motor.- Gearbox.- Wire rope press roller / wire rope anti-overlapping 5.- Drum Open winch advantages: In general, open winches allow higher lifting capacities, higher speeds and higher FEM working groups. Possibility of working with motors of 1,0 rpm., 1,000 rpm., and 7 rpm., Bigger motor sizing. ommercial motors usage to adequate customer standards. One motor instead with less failure possibility instead of two hoist with two motors for the same lifting capacity. Direct shaft from motor to gearbox to drum with flexible and intermediate assemblies, absorbing the shocks at the time of lifting. Figure 1 Example of open winch with single drum without connections in the drum. True vertical lift, with stable hook at the lifting time. Easy access to the components for easy maintenance. External brake for easy access and maintenance Wire rope press roller/ Wire rope anti-overlapping and The anti-overlapping device target is to avoid the wire rope come out from the drum hole. Figure 2 Example of open winch with double drum without connections in the drum. The inaccuracies in assembly, as well as the deformation of the structures and wear of parts in operation, cause huge additional forces, especially in the gearbox output shaft. These forces will cause bending forces that finally may cause fatigue fractures and damages of bearings and gears. The barrel coupling installed between the gearbox and the drum makes the union statically determined, and therefore avoids the occurrence of high bending moments.
