Electric Hoist Crab

Electric hoists (also known as electric chain hoists) are used for lifting or lowering material with the use of its electric motor and controller to easily lift and lower, with the ability to adjust the speed of the hoist.Hoists are mechanical or electro-mechanical lifting devices that rely on mechanical advantage to move objects vertically and support hanging loads. Mechanical hoist equipment distributes weight by using pulleys or gears to transfer low force over long distances into larger forces applied over shorter distances.
