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 could move loads between any areas within the boom's arc of rotation. Light duty units are utilized inside factories and warehouses for loads weighing up to 5 tons. The BestJibCranes.com web site features 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 could stand by themselves. The horizontal boom in this particular case is connected to a pivoting vertical column which is anchored firmly to the building floor. This kind of jib crane is able to rotate a full 360 degrees and requires 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 floor of the building and the overhead steel structure. These jib-cranes offer 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 offer a horizontal boom which is connected to the building wall rather than the typical vertical column. These machine are great in places where the full 360 degree rotation is not required and offer up to 200 degrees of rotation.
Depending on how the boom is supported, there are two model varieties. One kind uses 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.
