Winches offer greater pulling power

These products are also Ex rated, suitable for safe operation within hazardous areas. They are particularly suited to oil and gas production plants, both offshore and land based, as well as chemical installations and a wide range of other industrial operations where potentially explosive atmospheres may occur.

A durable steel structure is combined with a long drum to provide good rope capacity with four layer spooling, and a drum/rope diameter ratio which ensures optimum rope life operation. An integrated planetary gearbox also utilises exhaust air cooling for 100% duty cycles with minimum maintenance and maximum reliability. The winches are easy to install and have a low operating noise level. A winch mounted control lever is provided as standard for precise operation and variable speed control. Optional twin button or lever pendant controllers can also be supplied for remote operation.

Emergency stop and overload protection are incorporated as standard, with other optional features including pressure roller, rope drum grooving, slack rope detector, welded pulling frame and drum guard (fitted as standard to CE winch version). A split drum arrangement can also be provided which facilitates pulling/spooling-off operations to take place on adjacent sides of the drum at the same time.

Within the full range of JDN lifter/puller winches, the large capacity puller winches are supplemented by lightweight aluminium framed Profi lifters with capacities of 500 or 800kg. Rugged, steel framed products can also be supplied for either lifting or pulling operations with capacities from 1200 to 2000kg and motor ratings from 2.2 to 5.5kW. All products of 1200kg capacity or more can also be supplied with offshore painting (yellow) as an option. Some products can also be equipped with an emergency lowering feature, suitable for operation in accident/emergency evacuation situations.

All products are designed to operate at 6 bar air pressure and can be used with varying rope diameters 8-12mm or 5/16”-1/2” in size.

The Ex ratings for the standard products are Ex II 2 GD IIB T4(X) / II 3 GD IIB T4 (X). This rating can be increased where increased spark protection has been specified to Ex II 2 GD IIB T4 (X).
