The winch comprises of two mooring drums of fabricated construction, mounted in a reverse waterfall configuration. Both drums fitted with fixed high tensile steel mainshaft. The mainshafts supported on the fabricated winch baseplate by heavy duty roller type bearings. The bearings are mounted in fabricated steel housings, fitted with external grease lubrication points, bolted to the winch baseplate.

A central pinion shaft is mounted between the winch drums, carrying all necessary dog clutches, support bearings and final drive pinion gears, allowing independent operation of the drums through the drive package one at a time.

Transmission is from a set of low speed high torque medium pressure hydraulic motors. The motors are positioned at one side of the winch, driving through a common totally enclosed reduction gearbox.

The drums are each fitted with a wrap up type band break, which is hydraulically released and spring applied, giving fail safe to On mode of operation. The brake would operate through a hydraulic cylinder and spring system through mechanical linkages to provide the required holding load. All brake straps are lined with a high grade non asbestos marine lining that is bolted to position.

An adjustable drag break is installed to each drum for controlled wire pay out. Drag brake is mounted on a pinion shaft geared to the main gear on the other side of the drive shaft. The brake is of the multi plate type, pneumatically controlled, complete with connections for an incoming fresh water cooling supply to dissipate the generated heat.

An automatic wire spooling system is provided for both drums, designed for below drum spooling. The system comprises a leadscrew and drive tongue, guide bar, side support frames, fabricated bushed carriage complete with vertical rollers, manually operated clutch and chain drive mechanism comprising driver and driven sprockets, chain and fabricated steel guard.

The unit is powered by the electro hydraulic power pack mounted below.
