Jib Crane Models
Jib cranes are made up of a trolley hoist on a horizontal load-bearing boom. This boom is connected to a pivoting vertical member and up to 20 feet long. Jib cranes could transport loads between any areas within the boom's arc of rotation. Light duty units are utilized within warehouses and factories for loads weighing as much as 5 tons. The BestJibCranes.com website showcases the major jib crane models as being either free-standing, wall-mounted or mast mounted.
Free Standing
The free-standing jib crane models do not require any support from the building structure and can stand by themselves. The horizontal boom in this case is attached to a pivoting vertical column which is anchored firmly to the floor of the building. This type of jib crane can rotate a full 360 degrees and requires a foundation made of either concrete or steel.
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 provide 360 degrees of rotation with the advantage of not requiring the massive foundation needed for free-standing units.
Wall Mounted
The wall-mounted jib cranes provide a horizontal boom that is attached to the building wall rather than the normal vertical column. These machine are ideal in areas where the full 360 degree rotation is not needed and provide up to 200 degrees of rotation.
Depending on how the boom is supported, there are two model varieties. One type uses a tie rod from above the boom which is attached to the wall. The other kind supports the boom from below by utilizing a cantilever brace that is attached to the wall also.
