Jib Crane Types
The trolley hoist on a horizontal load-bearing boom are key features on Jib cranes. The boom is secured to a vertical mast that measures 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 inside factories and warehouses for loads weighing as much as 5 tons. The BestJibCranes.com website showcases the major kinds of jib cranes as being either free-standing, wall-mounted or mast mounted.
Free Standing
The free-standing jib crane units do not require any support from the building structure and are able to stand by themselves. The horizontal boom in this particular situation is attached to a pivoting vertical column which is anchored solidly to the building floor. This kind of jib crane is able to rotate a full 360 degrees and needs a foundation made of either steel or concrete.
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 needed for free-standing units.
Wall Mounted
The wall-mounted jib cranes provide a horizontal boom that is attached to the wall of a building rather than the regular vertical column. These machinery are ideal in areas where the full 360 degree rotation is not needed and provide up to 200 degrees of rotation.
There are two model varieties, depending on how the boom is supported. One of the types utilizes a tie rod that is connected from above the wall to the boom. The other kind supports the boom from below by using a cantilever brace that is connected to the wall too.
