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 which measures up to 20 feet long. Jib cranes can move loads between any areas within the boom's arc of rotation. Light duty units are used within warehouses and factories for loads weighing as much as 5 tons. The BestJibCranes.com website showcases the major jib crane types as being either wall-mounted, mast mounted or free-standing.
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 anchored firmly to the floor of the building. This kind of jib crane could rotate a full 360 degrees and needs 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 attached to the floor of the building and the overhead steel structure. These jib-cranes provide 360 degrees of rotation with the benefit of not needing the massive foundation needed 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 equipments provide up to 200 degrees of rotation and are great in places where the full 360 degree rotation is not needed.
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 also attached to the wall.
