Types of Jib Cranes
Jib cranes are made up of a trolley hoist on a horizontal load-bearing boom. This boom is attached to a pivoting vertical member and up to 20 feet long. Jib cranes could transport loads between any areas within the boom's arc of rotation. Light duty models are utilized inside factories and warehouses for loads weighing up to 5 tons. The website BestJibCranes.com showcases the major types of jib cranes as being either mast mounted, free-standing or wall-mounted.
Free Standing
Free-standing jib cranes can stand alone not requiring support from the building structure. The horizontal boom in this particular case is connected to a pivoting vertical column which is firmly anchored to the floor of the building. This type of jib crane could 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 which are attached to the building floor and the overhead steel structure. These jib-cranes offer 360 degrees of rotation with the benefit of not needing the massive foundation needed for free-standing units.
Wall Mounted
The wall-mounted jib cranes provide a horizontal boom which is connected to the building wall rather than the typical vertical column. These equipments are great in areas where the full 360 degree rotation is not required and provide up to 200 degrees of rotation.
Depending on how the boom is supported, there are two model varieties. One kind utilizes a tie rod from above the boom that is connected to the wall. The other type supports the boom from below by utilizing a cantilever brace which is connected to the wall too.
