Winch lifts are devices used to lift and move heavy objects, featuring a cord with a hook and motorized pulley. Types include winch lift trucks with forks or platforms, overhead hoists mounted on rails, and specialized motor lifts for lifting engines.
The term “winch lift” can refer to several devices used to lift and/or move heavy objects. Most of these devices feature a cord with a hook attached to the end, and most also have some sort of motor to spin the pulley that that cord is wound around. The specific structure of the winch lift can vary from there; Forklifts, for example, are hand trucks equipped with forks for lifting heavy objects, while overhead hoists mount to rails and trolleys above the ground to lift and move objects along a set path.
Winch lift trucks are manually operated trucks with forks or a platform used for lifting objects. A winch is mounted to the rear of the unit and the cable runs over the trolley and down to the platform or forks. It is likely that the winch lift will be motorized, but manual winches also exist. If the unit is motorized, the user will activate a switch that will turn the pulley, thereby retracting the cable and raising the forks or platform. This easily lifts the heavy object off the ground for moving or maneuvering. If the unit is not motorized, a crank must be turned to rotate the pulley and retract the cable. The winch dolly usually comes with wheels or casters to allow for exceptionally easy movement.
Overhead winch lift systems are mounted on a steel rail that runs overhead in a factory or warehouse. The winch is mounted on a carriage which can move freely along the rail, making it possible to move objects. This system is almost always motorized; the motor turns the pulley around which the cable is wound, and when the cable is out, it can be secured around a load to be moved using the hook at the end of the cable. Once the load is secured, the cable can be retracted and the load lifted. The user operates the hoist winch using a hand controller which drives the pulley and trolley which moves along the steel track.
There are other types of winch lift systems as well. Some are highly specialized, such as motor lifts. These systems are specifically designed to lift engines out of car or truck engine bays. A steel frame will support the weight of the engine and a cable winch system mounted to the steel frame will allow for lifting capabilities by feeding or retracting the cable.
