Why crane system need buffers?

Three kinds of buffers are used widely, spring buffer, rubber buffer and hydraulic buffer. Spring buffer is reliable and convenient to maintain. Rubber buffer has simple structure. Hydraulic buffer can absorb large hitting energy and has no rebound effect.

When limiting stopper of travelling extreme position or brake is in trouble, due to the inertia, the crane system moving in the end or the trolley on the main girder, will hit against the stopper set in the position. But crane buffer can absorb the travelling energy of crane system or trolley and reduce impulsion. Buffers should be set between the bridge cranes travelling on the same track, or between the double trolleys on the same girder.
