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 units are used inside warehouses and factories for loads weighing up to 5 tons. The BestJibCranes.com website features the major types of jib cranes as being either free-standing, wall-mounted or mast mounted.
Free Standing
The free-standing jib crane models do not need any support from the building structure and can stand by themselves. The horizontal boom in this case is connected to a pivoting vertical column that is firmly anchored to the floor of the building. This type of jib crane could rotate a full 360 degrees and needs a foundation made of either steel or concrete.
Mast-Type
The mast-type jib cranes feature a vertical column which is supported by pivot points at the top and the bottom which 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 needed for free-standing units.
Wall Mounted
The wall-mounted jib cranes provide a horizontal boom that is connected to the wall of a building as opposed to the normal vertical column. These equipments are great in areas where the full 360 degree rotation is not required and offer up to 200 degrees of rotation.
There are two model varieties, depending on how the boom is supported. One of the kinds uses a tie rod which is attached from above the wall to the boom. The other type supports the boom from below by utilizing a cantilever brace which is also attached to the wall.
