Shop TWG Pullmaster H25 Rapid Reverse Hoists
The TWG Pullmaster H25 is a high performance, high efficiency planetary winch with a 'Rapid Reverse' feature which provides for reversing or lowering line speeds 4.67 times fastr than forwarding or hoisting line speeds. The automatic, multi disc brake of this unit is effective in one direction only and achieves exceptionally smooth lowering of a load. The maximum load can be smoothly and positively controlled at a minimum line speed of 40 fpm (bare drum) and should not be lowered with speed exceeding the forward or hoisting line speed. Only loads, reduced by a ratio of 4.67 of the maximum capacity of the winch, can be safely lowered at maximum reversing speed.
The TWG Pullmaster H25 winch is powered by a hydraulic gear motor and the required reduction ratio of 40.8:1 is established by two planetary stages. The hydraulic motor drives direct into the planetary reductions. When the forward hoisting rotation is stopped an over-running clutch, installed between the brake assembly and the motor drive shaft, will lock and the multi-disc brake applies automatically. The multi-disc brake is spring applied and pressure released and has static and dynamic function. When the hydraulic motor is powered for reverse or lowering the brake is released automatically and the primary reduction stage is locked out, resulting in the faster reversing or lowering speed. The speed is controlled by modulation of a single control lever. A counterbalance valve is not required for dynamic braking. All moving parts of the Pullmaster H25 planetary hydraulic winch are totally enclosed and run in an oil bath, assuring a long, trouble free service with a minimum requirement for maintenance.
