Engine crane

Engine cranes are typically mounted on large casters so that an engine can be lifted straight up out of an engine compartment and then rolled away from the immobile vehicle frame. Most engine cranes are equipped with a telescopic boom which can be extended to reach engine blocks located further into the engine compartment. At the end of the boom there is a grab hook where lifting chains, slings or a load leveler can be attached for lifting purposes. ==Types of engine cranes==

Engine cranes/hoists have three commonly used types: hydraulic hoists, chain hoists, and electric chain hoists. The type of engine crane is chosen based on the amount of weight the user is lifting, cost, and convenience. Hydraulic hoist The most commonly used engine crane is the hydraulic hoist. Chain hoist Chain hoists are ceiling-mounted engine cranes that are often slower than hydraulic hoists and electric chain hoists. Chain hoists utilize a system of gears and chains to multiply forces that are produced when the operator is pulling the chain to lift the engine. A braking system prevents the engine from unintentionally lowering by the user. Electric chain hoist The electric chain hoist, also known as the "electric hoist", is the least used type of engine crane. The operation is similar to the chain hoist in the way that chains are used to lift the engine. The electric chain hoist uses an electric motor operated by remote control to lift the engine, unlike the chain hoist where the operator has to manually pull a chain. Although the electric chain hoist is faster in operation, this hoist is also more costly than a chain hoist. == Gallery ==
