A pulley hoist is a device used for lifting heavy objects, consisting of one or more pulleys and a hook or safety system. It can be manually or motorized, and is commonly used in industrial environments, garages, and workshops. The user pulls the rope or chain to activate the pulleys, and a motorized hoist is powered by a motor. It can be mounted on an overhead beam or rail for easy positioning.
A pulley hoist is a device used to lift heavy objects. This device usually consists of one or more pulleys through which a chain or rope can be passed, and a hook or other safety system to which objects can be attached for lifting. Some models of pulley hoists are powered to lift extremely heavy objects, while others are manually operated by pulling the rope or chain. The size and function of the hoist can vary, as can the price of the unit, depending on its intended use. They are commonly used in industrial environments, garages and workshops.
The system relies on one or more pulleys, which are essentially wheels, usually made of metal, mounted on axles to enable the wheels to turn. The perimeter of the wheel may be grooved to keep the rope, chain or webbing more securely in place during use, and the pulley itself will be mounted within a frame, also usually made of metal. The pulley hoist may have only one pulley, but it is likely that the system will have more than one pulley for more effective lifting or moving of heavy objects.
To use a pulley hoist, the user pulls the rope or chain at one end of the system. The opposite end of that rope or chain is attached to a stable object, and between the two ends the rope or chain runs through pulleys. When the user pulls on the rope or chain, the pulleys activate; one or more pulleys are attached to the object being moved, so when the rope is pulled, the pulleys rise. There are other methods as well: an independent hook can be incorporated into the system so that the pulley itself is not attached to the object being lifted.
A motorized pulley hoist works in a similar way, but instead of being hand-operated, it is powered by a motor that pulls the rope or chain. The motor is designed to take the load of heavier objects that a human couldn’t lift, even with the pulley system. Sometimes the pulley hoist is mounted on an overhead beam or rail, which allows a person to adjust the position of the hoist in relation to the object being lifted. Once the object is lifted, it can be moved along the track to a different location.
