Jib Crane Models
The trolley hoist on a horizontal load-bearing boom are key features on Jib cranes. The boom is secured to a vertical mast which measures up to 20 feet long. Jib cranes can move loads between any areas within the boom's arc of rotation. Light duty units are utilized in factories and warehouses for loads weighing up to 5 tons. The BestJibCranes.com website features the major jib crane models as being either mast mounted, free-standing or wall-mounted.
Free Standing
Free-standing jib cranes could stand alone not needing support from the building structure. The horizontal boom in this specific case is connected to a pivoting vertical column which is solidly anchored to the building floor. This kind of jib crane can rotate a full 360 degrees and needs a foundation made of either steel or concrete.
Mast-Type
The vertical column on the mast-type jib cranes are supported by pivot points at the top and the bottom. These pivots are connected to the floor of the building and the overhead steel structure. These jib-cranes offer 360 degrees of rotation with the benefit of not requiring the massive foundation required for free-standing units.
Wall Mounted
Wall mounted jib cranes are connected to the building wall rather than supporting a regular vertical column. These cranes offer a horizontal boom. 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 types uses a tie rod which is attached from above the wall to the boom. The other type supports the boom from below by using a cantilever brace that is also attached to the wall.
