Crane Types

Single girder cranes Overhead.  – The crane consists of a single bridge girder supported on two end trucks. It has a trolley hoist mechanism that runs on the bottom flange of the bridge girder.

Gantry Crane : The bridge (which carries the hoist and trolley) is supported by a pair of rigid steel legs which, in turn, are carried by a pair of end trucks along the floor-level runway. The gantry crane provides the same performance characteristics that an overhead bridge crane offer

Monorail – For some applications such as production assembly line or service line, only a trolley hoist is required. The hoisting mechanism is similar to a single girder crane with a difference that the crane doesn’t have a movable bridge and the hoisting trolley runs on a fixed girder. Monorail beams are usually I-beams (tapered beam flanges).

Jib Crane: This type of crane consists of a pivoting head and boom assembly, which carries a hoist and trolley unit. The pivoting head is supported either by a floor-mounted mast providing 360°-boom rotation or by an existing building column, which provides 180° of boom rotation. The jib crane can also be motorized to provide precise spotting of loads, however, the hook location is along a radial path rather than a simple X-Y arrangement.

Double Girder Overhead Crane : Double Girder Bridge Cranes are most frequently used where capacities over 10 tons and/or spans of 60 to 100 ft are needed. They can be utilized at any capacity where extremely high hook lift is required because the hook can be pulled up between the girders. Double Girder Bridge Cranes are often used where high speeds and heavy service are required.
