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 are able to 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 website BestJibCranes.com showcases the major jib crane types as being either free-standing, wall-mounted or mast mounted.



Free Standing

Free-standing jib cranes could stand alone not needing support from the building structure. The horizontal boom in this specific situation is connected to a pivoting vertical column that is anchored firmly to the floor of the building. This type of jib crane can 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 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

Wall mounted jib cranes are attached to the building wall instead of supporting a regular vertical column. These cranes provide a horizontal boom. These equipments offer up to 200 degrees of rotation and are great in areas where the full 360 degree rotation is not needed.



Depending on how the boom is supported, there are two model varieties. One type uses 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 connected to the wall also.
