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 could transport loads between any areas within the boom's arc of rotation. Light duty models are utilized in factories and warehouses for loads weighing up to 5 tons. The BestJibCranes.com website showcases the major types of jib cranes as being either mast mounted, free-standing or wall-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 specific case is attached to a pivoting vertical column that is solidly anchored to the building floor. 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 bottom and the top. These pivots are attached to the floor of the building and the overhead steel structure. These jib-cranes provide 360 degrees of rotation with the benefit of not requiring the massive foundation required for free-standing units.
Wall Mounted
The wall-mounted jib cranes offer a horizontal boom which is attached to the wall of a building rather than the normal vertical column. These machinery are great in places where the full 360 degree rotation is not required and provide up to 200 degrees of rotation.
Depending on how the boom is supported, there are two model varieties. One type utilizes a tie rod from above the boom which is attached to the wall. The other type supports the boom from below by utilizing a cantilever brace that is connected to the wall also.
