Jib Crane Models
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 are able to move loads between any areas within the boom's arc of rotation. Light duty units are used within warehouses and factories for loads weighing up to 5 tons. The web site BestJibCranes.com showcases the major jib crane models as being either mast mounted, free-standing or wall-mounted.
Free Standing
The free-standing jib crane models do not need any support from the building structure and are able to stand by themselves. The horizontal boom in this case is connected to a pivoting vertical column which is firmly anchored 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 mast-type jib cranes feature a vertical column that is supported by pivot points at the top and the bottom that are connected 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 connected to the building wall rather than supporting a regular vertical column. These cranes offer a horizontal boom. These machine are ideal in areas where the full 360 degree rotation is not needed and offer up to 200 degrees of rotation.
There are two model varieties, depending on how the boom is supported. One of the kinds utilizes a tie rod that is connected from above the wall to the boom. The other variety supports the boom from below by using a cantilever brace that is connected to the wall too.
