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 could transport loads between any areas within the boom's arc of rotation. Light duty models are used in warehouses and factories for loads weighing as much as 5 tons. The BestJibCranes.com web site showcases the major jib crane models as being either wall-mounted, mast mounted or free-standing.
Free Standing
Free-standing jib cranes could stand alone not requiring support from the building structure. The horizontal boom in this case is attached to a pivoting vertical column that is anchored firmly to the floor of the building. This type of jib crane needs a foundation made of either concrete or steel and is able to rotate a full 360 degrees.
Mast-Type
The mast-type jib cranes feature a vertical column which is supported by pivot points at the bottom and the top that are connected to the building floor and the overhead steel structure. These jib-cranes offer 360 degrees of rotation with the benefit of not requiring the massive foundation required for free-standing units.
Wall Mounted
Wall mounted jib cranes are connected to the wall of the building rather than supporting a typical vertical column. These cranes offer a horizontal boom. These equipments provide up to 200 degrees of rotation and are great in areas where the full 360 degree rotation is not required.
There are two model varieties, depending on how the boom is supported. One of the types utilizes a tie rod which is connected from above the wall to the boom. The other kind supports the boom from below by using a cantilever brace which is connected to the wall too.
