An engine hoist, also known as a cherry picker, is used to remove and install engines in vehicles. It typically uses a hydraulic cylinder and steel frame with an adjustable arm and optional folding legs. Other versions include chain drops, drag pullers, and electric wire rope hoists. It is important to avoid leaving the motor hanging from the hoist for extended periods to prevent premature failure.
An engine hoist is a device used to remove and install an engine in a passenger car or truck. Commonly known as a cherry picker, one of the most commonly used motor hoist designs uses a hydraulic cylinder attached to a steel frame with a hook hanging from the top. An adjustable upper arm allows the reach potential of the motor hoist to be adjusted, while optional folding legs allow the tool to be stored against a wall or out of the way when not in use. Other versions of the hoist consist of chain drops, drag pullers, and electric wire rope hoists.
To complete many different types of automotive engine or transmission repairs, the engine often must be removed from the vehicle. This is accomplished through the use of a hoist motor. On many vehicles, once the engine is disconnected from the chassis mounts, electrical harness, and other fluid lines, an engine lift can be attached to the engine using a lift bracket or chains and lifted up and out of the vehicle. . However, on many front-wheel drive vehicles, the engine requires removal from under the chassis. In this situation, the body is often locked in a raised position while the engine is lowered from the chassis using a hoist.
When an overhead beam, tree limb, or beams are available, the hoist, chain falls, or electric cable winch can often be used to pull or replace a motor. When no air support is present, the cherry picker is the best tool for the job. One setback for the cherry picker is that the use of this type of motor hoist requires a solid floor on which to operate. The soft ground will allow the picker’s wheels or wheels to sink into the ground, preventing the cherry picker from being easily pulled out and away from the vehicle with the engine hovering.
The cherry picker can be placed on a thick sheet of plywood covering soft ground to allow the engine hoist to be pulled out and maneuvered under the vehicle. One precaution to take when using any type of motor hoist is to avoid leaving a motor hanging from the hoist for extended periods of time. Constant stress from the motor hanging unsupported from the hoist can cause premature failure of the hoist, including motor damage from a sudden drop to the floor or ground.
