MONORAIL CRANES are most effective in production applications where materials are repetitively moved from one point to another. The monorail hoist and trolley run on a single stationary beam, normally include H-beam or I-beam
GANTRY CRANES
Is similar to a bridge crane, but instead of moving on suspended runways, the crane uses legs to support the bridge, trolley, and hoist. The crane legs travel on fixed rails embedded in, or laid on top of the floor
JIB CRANE
has a horizontal member (known as jib or boom) that supports a moveable hoist fixed to a wall or to a floor-mounted pillar.
SINGLE GIRDER CRANES The bridge consists of one girder beam supported on each side by an end truck. The trolley and hoist are underhung, meaning they run on the bottom flange of the single girder
DOUBLE GIRDER CRANES There are two girder beams that make up the bridge, and they are supported by an end truck on each side. The trolley and hoist run on a rail installed above or below the bridge girders.
