Guide drum grooving extends winch rope life

Optional rope guide drum grooving is now available for the air operated winches to eliminate excessive wire rope wear as a result of random or zig-zag pattern rope layering.

Optional rope guide drum grooving is now available for the air operated winches supplied by J D Neuhaus .

This is designed to eliminate excessive wire rope wear that develops over time as a result of random or zig-zag pattern rope layering, which can occur.

Rope guide grooving is provided over the full drum width but is limited to approximately 80% of the drum circumference.

The remaining drum circumference is left ungrooved and this has proved to be the most effective way of initiating the correct guiding characteristics not only for the first rope layer, but also for subsequent layers.

This results in orderly winding over the full wire rope length, minimising rope damage and maximising rope service life, while also maintaining safe-working-practice conditions.

The JDN air operated winches are suitable for use in hazardous area environments and can also be provided with a range of further options including long drums, drum guards, pressure roller, free spooling clutch, second rope end fastening and slack rope detection.

These can be supplemented with safety features of emergency stop valve, overload protection and limit switch systems, together with enhanced operation via adaption plate, pulling frame and emergency lowering device.

Other optional environmental features include offshore paint finish can also be provided where required.

In common with the JDN hoists, winches utilise a well proven self lubricating vane motor with an integrated brake function.

These units have fewer components, with reduced maintenance requirements, eliminating the need for additional air lubrication.

They also feature exhaust air cooling of the planetary gear which is integrated into the drum mechanism, leading to maximum reliability.
