2) Crane Manufacturers

As applies to Members of the Material Handling Industry of America (MHIA), this term usually applies to manufacturers of overhead traveling cranes, jib cranes, stacker cranes, and gantry cranes to the exclusion of mobile cranes, tower cranes or devices otherwise referred to as construction cranes.

3) Semigantry crane

A gantry crane designed to have one "leg" of the crane supporting an end of the bridge and the other end of the bridge is supported by an end truck running on an elevated rail or runway.  Often referred to as a semigantry crane.

4) Underhung crane

An electric overhead traveling crane having the end trucks supported on track attached to the bottom flanges of the beam; or supported on bottom flanges of beams.  These beams make up the crane runway.

5) Gantry crane

A crane similar to an overhead crane except that the bridge for carrying the trolley or trolleys (with lifting device) is rigidly supported on two or more legs running on fixed rails or other runway.

6) Jib crane

A stationary or fixed crane that utilizes a cantilevered bridge (girder) supported from a stationary vertical support.  The jib crane generally utilizes a lifting device (hoist) that is mounted on the horizontal boom (jib).

7) Straddle crane

A crane that is configured to "straddle" a load and often is wheeled. Often used in lumber yards or to move large containers at sea ports.

8) Tower crane

A crane designed to handle very large, heavy loads used at construction sites and for the loading and unloading of sea going containers.

9) Overhead crane

A crane with a single or multiple girder (bridge girder) bridge carrying a movable or fixed hoisting mechanism and traveling on an overhead fixed runway structure.

10) Stacker crane

The stacker crane in appearance looks like a conventional bridge crane except that in place of a hoist, a rotating ridged or telescoping mast is suspended from the bridge trolley with the mast equipped with a load handling device such as single or double forks or a grab. These cranes can be manually operated or powered and are used where the carne spans multiple aisles allowing for the storage and retrieval within any aisle of items such as coils of steel.

14) Push type crane

An overhead traveling crane whose horizontal travel is powered manually or by the operator.  Often work station cranes are push type cranes.  This crane may or may not utilize powered hoist or lifting mechanisms.

15) Top running crane

An electric overhead traveling crane having the end trucks supported on rails attached to the top of the crane runways.
