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 units are used within factories and warehouses for loads weighing up to 5 tons. The website BestJibCranes.com showcases the major types of jib cranes as being either wall-mounted, mast mounted or free-standing.
Free Standing
Free-standing jib cranes could stand alone not needing support from the building structure. The horizontal boom in this situation is connected to a pivoting vertical column that is firmly anchored to the floor of the building. This kind of jib crane can 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 top and the bottom which are attached to the building floor and the overhead steel structure. These jib-cranes provide 360 degrees of rotation with the advantage of not needing the massive foundation needed for free-standing units.
Wall Mounted
The wall-mounted jib cranes offer a horizontal boom that is attached to the wall of a building as opposed to the typical vertical column. These machine are ideal in areas where the full 360 degree rotation is not required and offer up to 200 degrees of rotation.
There are two model varieties, depending on how the boom is supported. One of the types uses 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 that is also attached to the wall.
