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 transport loads between any areas within the boom's arc of rotation. Light duty units are utilized inside factories and warehouses for loads weighing as much as 5 tons. The BestJibCranes.com website features the major jib crane types as being either mast mounted, free-standing or wall-mounted.
Free Standing
Free-standing jib cranes are able to stand alone not requiring support from the building structure. The horizontal boom in this specific situation is attached to a pivoting vertical column that is anchored solidly to the floor of the building. This kind of jib crane needs a foundation made of either steel or concrete and is able to rotate a full 360 degrees.
Mast-Type
The vertical column on the mast-type jib cranes are supported by pivot points at the bottom and the top. These pivots are attached to the building floor and the overhead steel structure. These jib-cranes provide 360 degrees of rotation with the benefit of not requiring the massive foundation needed for free-standing units.
Wall Mounted
Wall mounted jib cranes are attached to the building wall instead of supporting a regular vertical column. These cranes provide a horizontal boom. These equipments offer up to 200 degrees of rotation and are ideal in places where the full 360 degree rotation is not needed.
Depending on how the boom is supported, there are two model varieties. One type utilizes a tie rod from above the boom that is attached to the wall. The other kind supports the boom from below by using a cantilever brace that is attached to the wall also.
