Jib Crane Types
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 move loads between any areas within the boom's arc of rotation. Light duty units are utilized within factories and warehouses for loads weighing up to 5 tons. The website BestJibCranes.com showcases the major kinds of jib cranes as being either wall-mounted, mast mounted or free-standing.
Free Standing
Free-standing jib cranes are able to stand alone not requiring support from the building structure. The horizontal boom in this specific case is attached to a pivoting vertical column that is firmly anchored to the building floor. This type of jib crane is able to rotate a full 360 degrees and requires 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 top and the bottom which are connected to the floor of the building and the overhead steel structure. These jib-cranes provide 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 offer a horizontal boom which is connected to the building wall rather than the typical vertical column. These equipments are great in places where the full 360 degree rotation is not needed and offer up to 200 degrees of rotation.
Depending on how the boom is supported, there are two model varieties. One type utilizes a tie rod from above the boom which is connected to the wall. The other type supports the boom from below by utilizing a cantilever brace that is connected to the wall as well.
