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 move loads between any areas within the boom's arc of rotation. Light duty models are used within 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
The free-standing jib crane units do not require any support from the building structure and could stand by themselves. The horizontal boom in this specific case is connected to a pivoting vertical column that is anchored firmly to the building floor. This kind of jib crane needs a foundation made of either concrete or steel and can 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 attached to the building floor and the overhead steel structure. These jib-cranes offer 360 degrees of rotation with the advantage of not needing the massive foundation required for free-standing units.
Wall Mounted
Wall mounted jib cranes are attached to the wall of the building rather than supporting a typical vertical column. These cranes offer 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 required.
Depending on how the boom is supported, there are two model varieties. One type utilizes a tie rod from above the boom which is attached to the wall. The other kind supports the boom from below by using a cantilever brace that is also connected to the wall.
