Shop TWG Pullmaster M8 Hoists
The TWG Pullmaster M8 is a high performance, high efficiency planetary winch, having equal speed in forward and reverse rotation. The automatic, multi-disc type 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 M8 is powered by a hydraulic gear motor and the required reduction ratio of 34:1 is established by two planetary stages.
The hydraulic motor drives direct into the planetary reductions. An over-running clutch installed between the drive shaft and the brake assembly, permits free rotation in the 'hoisting' direction without affecting the brake. During 'lowering' operation the over-running clutch locks causing the brake disc to rotate between a series of divider plates. Dynamic braking is then achieved by modulation of the winch control handle. When the control is returned to the neutral position, the brake applies automatically.
A counterbalance valve or brake valve is not required for smooth and positive 'Down' control of the Pullmaster M8 planetary winch. All moving parts of the Pullmaster Model M8 planetary winch are totally enclosed and run in an oil bath. Anti-friction bearings are used on all turning components, assuring a long, trouble free service with a minimum requirement for maintenance.

- NOTE: Drum Storage based on Ø1/2" wire rope.
Standard cable anchor is suitable for 1/4 - 3/8 inch diameter wire rope. 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.
