Jib Crane Models
The trolley hoist on a horizontal load-bearing boom are key features on Jib cranes. The boom is secured to a vertical mast which measures up to 20 feet long. Jib cranes are able to transport 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 BestJibCranes.com web site features the major types of jib cranes as being either free-standing, wall-mounted or mast mounted.
Free Standing
Free-standing jib cranes could stand alone not requiring support from the building structure. The horizontal boom in this specific case is connected to a pivoting vertical column which is anchored firmly to the building floor. This type of jib crane could rotate a full 360 degrees and requires a foundation made of either steel or concrete.
Mast-Type
The vertical column on the mast-type jib cranes are supported by pivot points at the bottom and the top. These pivots 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
The wall-mounted jib cranes provide a horizontal boom that is attached to the wall of a building as opposed to the regular vertical column. These machinery are ideal in places where the full 360 degree rotation is not needed and provide up to 200 degrees of rotation.
Depending on how the boom is supported, there are two model varieties. One type 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 which is also connected to the wall.
