Table 1421 Materials handling energy savings hoists and cranes

Problem

Solution

Cranes powered by compressed air Idling

Too many moves

Most loads too small for full use of hoist or crane capacity Cranes running during off hours

Use electrical hoists and cranes (5 hp on compressor = 1 hp on hoist) Use switches to turn crane off when not in use for a preset time (5-10 min) Package in larger unit loads Size the crane or hoist to load moved most often

Turn off as part of regular closing check list
