Jib Crane Models
Jib cranes are made up of a trolley hoist on a horizontal load-bearing boom. This boom is attached to a pivoting vertical member and up to 20 feet long. Jib cranes can move loads between any areas within the boom's arc of rotation. Light duty units are used inside factories and warehouses for loads weighing up to 5 tons. The BestJibCranes.com web site features the major jib crane models as being either mast mounted, free-standing or wall-mounted.
Free Standing
Free-standing jib cranes can stand alone not requiring support from the building structure. The horizontal boom in this specific case is attached to a pivoting vertical column which is firmly anchored to the floor of the building. This kind of jib crane requires a foundation made of either steel or concrete and could rotate a full 360 degrees.
Mast-Type
The mast-type jib cranes feature a vertical column that is supported by pivot points at the top and the bottom which are connected to the building floor and the overhead steel structure. These jib-cranes offer 360 degrees of rotation with the advantage of not requiring the massive foundation required for free-standing units.
Wall Mounted
The wall-mounted jib cranes offer a horizontal boom that is connected to the building wall as opposed to the regular vertical column. These machine offer up to 200 degrees of rotation and are ideal in areas where the full 360 degree rotation is not needed.
There are two model varieties, depending on how the boom is supported. One of the kinds uses a tie rod which is attached from above the wall to the boom. The other variety supports the boom from below by using a cantilever brace that is also attached to the wall.
