Although the simple definition of a winch is a mechanical device that is used to wind up a rope or cable, it generally consists of a spool that is sometimes referred to as a winch drum, attached to a crank. Winches used in heavy lifting industries can have sophisticated gear assemblies that are powered by hydraulic, pneumatic, or combustible engine drives. In some cases, operations will also need a winch that includes a mechanical brake or ratchet that prevents the rope from unwinding. Winches are often used to tow boats or cars, and may also be used to move stage equipment. Bishop Lifting Products stocks and supplies the most heavy duty hand winches, air winches, and electrical winches.
- Hand Powered Winches: Hand winches must be intricately engineered to provide strength and eliminate maintenance. Quality hand winches are constructed using solid steel gears and industrial strength components.
- Electrical Powered Winches: Electrical powered winches come in both fixed and portable models. These power winches offer machine cut gears, enclosed oil baths and durable cast aluminum construction. They also feature internal mechanical brakes.
- Heavy Duty Winches: Heavy duty winches are intended for the most demanding lifting applications and are able to lift up to 76,000 lbs. They include enclosed machine cut gearing and worm/spur gears
The versatility of winches allows them to be used in a multitude of applications, including setting up rigs, pulling pipe, moving industrial material, positioning objects on mast towers, raising telecommunication towers, moving materials for wind tower turbines and a host of other uses.
