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 are able to move loads between any areas within the boom's arc of rotation. Light duty models are utilized inside warehouses and factories for loads weighing as much as 5 tons. The BestJibCranes.com web site showcases the major types of jib cranes as being either mast mounted, free-standing or wall-mounted.
Free Standing
The free-standing jib crane units do not need any support from the building structure and are able to stand by themselves. The horizontal boom in this particular case is attached to a pivoting vertical column which is firmly anchored to the floor of the building. This type 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 that 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 provide 360 degrees of rotation with the advantage of not requiring the massive foundation needed for free-standing units.
Wall Mounted
The wall-mounted jib cranes provide a horizontal boom which is attached to the wall of a building rather than the normal vertical column. These machine are great in places where the full 360 degree rotation is not needed and offer 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 attached from above the wall to the boom. The other type supports the boom from below by using a cantilever brace that is attached to the wall too.
