Jib Crane Types
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 utilized in factories and warehouses for loads weighing as much as 5 tons. The BestJibCranes.com website showcases the major jib crane types as being either mast mounted, free-standing or wall-mounted.
Free Standing
Free-standing jib cranes are able to stand alone not requiring support from the building structure. The horizontal boom in this case is attached to a pivoting vertical column which is anchored firmly to the building floor. This type of jib crane is able to 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 needing the massive foundation required for free-standing units.
Wall Mounted
The wall-mounted jib cranes provide a horizontal boom that is attached to the building wall as opposed to the normal vertical column. These machinery are ideal 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 uses a tie rod from above the boom that 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.
