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.
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 with all or most movements powered by electric motors.
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.
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.
An electric overhead traveling crane having the end trucks supported on rails attached to the top of the crane runways.
The track mounted conductor system by which the moving equipment receives its electrical power. All of the electrical components that go into providing power to an electric overhead crane or jib crane. These components may include power bar, collectors, collector rings, pendent stations, and tagline/festooning.
An overhead crane generally used for ergonomic purposes and consisting of bridge(s) and runways made from enclosed metal track. End trucks attached to the bridge girder allow for ease of movement. The entire system is designed to allow workers to move loads by hand pushing the load with the assistance of a vertical lifting device such as a hoist or vacuum lifter.
CMAA is the Crane Manufacturers Association of America, Inc., an independent trade association affiliated with the Material Handling Industry. CMAA traces its roots to the Electric Overhead Crane Institute, known as EOCI, which was founded in 1927 by leading crane manufacturers of that time to promote the standardization of cranes as well as uniform quality and performance. The voluntary association was incorporated as the Crane Manufacturers Association of America, Inc. in 1955. Member Companies, representing the industry leaders in the overhead crane industry, serve the United States market from operations based in the United States, Canada, and Mexico.
An overhead traveling crane that utilizes a single bridge beam attached to the two runway/end trucks. This bridge beam or single girder supports a lifting mechanism or hoist that "runs" on the bottom flange of the bridge beam.
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.
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.
An overhead traveling crane designed so that the bridge carrying the trolley or trolleys is rigidly supported on two or more legs moving on fixed rails embedded in the floor (via end trucks attached to the bottom of each leg) or on wheels.
An overhead traveling crane designed with structurally reinforced bridge girders to allow greater span and loading capabilities. The reinforcement consists of utilization of trusses extended vertically and horizontally from the load bearing beam(s) of the crane bridge.
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.
