Shop TWG Pullmaster M50 Hoists
The TWG Pullmaster M50 is a high performance, high efficiency planetary winch, having equal speed in forward and reverse rotation. The automatic, multi-disc brake of this unit is effective in one direction only and achieves an exceptionally smooth lowering control the maximum load in a stepless operation. The TWG Pullmaster M50 planetary winch is powered by a hydraulic gear motor and the required reduction ratio of 116:1 is established by three planetary stages.
In forward rotation (hoisting) the hydraulic motor drives direct into planetary reductions without affecting the brake assembly. When forward rotation is stopped, an overrunning clutch between the brake assembly and the motor drive shaft will lock and the multi-disc brake will safely hold the maximum load. The multi-disc brake is spring applied and pressure released, requiring no calibration for fail-safe operation. When the hydraulic motor is powered for reverse rotation (lowering) the brake is released automatically and is then modulated for the desired lowering speed by a single control lever. A counterbalance valve or brake valve is not required for dynamic braking. All moving parts of the Pullmaster M50 planetary winch are totally enclosed and run in an oil bath, assuring long, trouble free service with a minimum requirement for maintenance.

For safety, 5 wraps of wire rope must be maintained at all times.
PullMaster products are not to be used to lift, hoist or move people. If your task involves lifting or moving people, you MUST use the proper equipment; not a PullMaster product. Wire rope anchors on winches are not designed to hold the rated load of the winch. You must keep at least five (5) wraps of wire rope on the drum to insure the wire rope doesn't come loose. Stay clear of suspended loads and of wire rope under tension. A broken wire rope or dropped load can cause serious injury or death. Make sure that all equipment, including the winch and wire rope, is maintained properly. Avoid shock loads. This type of load imposes a strain on a winch many times the actual weight of the load and can cause failure of the wire rope or of the winch. Winch operators must be trained in the proper, safe operations of the winch. The hydraulic system should use only high quality hydraulic oils from reputable suppliers. These oils should contain additives to prevent foaming and oxidation in the system. All winch systems should be equipped with a return line filter capable of filtering 10-micron particles from the system. Please contact OneHydraulics if you need assistance with fluid selection.
