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 can transport loads between any areas within the boom's arc of rotation. Light duty models are used in warehouses and factories for loads weighing up to 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 units do not need any support from the building structure and can stand by themselves. The horizontal boom in this particular case is connected to a pivoting vertical column which is solidly anchored to the floor of the building. This type of jib crane requires a foundation made of either steel or concrete and can rotate a full 360 degrees.
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 building floor and the overhead steel structure. These jib-cranes provide 360 degrees of rotation with the advantage of not needing the massive foundation required for free-standing units.
Wall Mounted
Wall mounted jib cranes are attached to the wall of the building rather than supporting a regular vertical column. These cranes offer a horizontal boom. These machine offer up to 200 degrees of rotation and are great in areas where the full 360 degree rotation is not required.
Depending on how the boom is supported, there are two model varieties. One kind utilizes a tie rod from above the boom that is attached to the wall. The other type supports the boom from below by utilizing a cantilever brace which is also connected to the wall.
