Jib Crane Types
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 move loads between any areas within the boom's arc of rotation. Light duty units are utilized in warehouses and factories for loads weighing up to 5 tons. The BestJibCranes.com website features the major types of jib cranes as being either wall-mounted, mast mounted or free-standing.
Free Standing
The free-standing jib crane models do not need any support from the building structure and could stand by themselves. The horizontal boom in this case is attached to a pivoting vertical column that is anchored solidly to the floor of the building. This type of jib crane is able to rotate a full 360 degrees and needs a foundation made of either concrete or steel.
Mast-Type
The mast-type jib cranes feature a vertical column that is supported by pivot points at the bottom and the top that are attached to the building floor and the overhead steel structure. These jib-cranes provide 360 degrees of rotation with the benefit of not needing the massive foundation required 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 regular vertical column. These machine provide up to 200 degrees of rotation and are great in places where the full 360 degree rotation is not required.
Depending on how the boom is supported, there are two model varieties. One type utilizes a tie rod from above the boom which is connected to the wall. The other type supports the boom from below by utilizing a cantilever brace that is connected to the wall too.
