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 models are utilized within warehouses and factories for loads weighing as much as 5 tons. The BestJibCranes.com website features the major jib crane models 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 situation is attached to a pivoting vertical column which is anchored firmly to the floor of the building. This type of jib crane requires a foundation made of either steel or concrete and could rotate a full 360 degrees.
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 floor of the building and the overhead steel structure. These jib-cranes offer 360 degrees of rotation with the advantage of not requiring the massive foundation required for free-standing units.
Wall Mounted
Wall mounted jib cranes are connected to the building wall rather than supporting a typical vertical column. These cranes provide a horizontal boom. These machine provide up to 200 degrees of rotation and are ideal in places where the full 360 degree rotation is not required.
Depending on how the boom is supported, there are two model varieties. One kind uses a tie rod from above the boom which is connected to the wall. The other type supports the boom from below by using a cantilever brace which is attached to the wall as well.
