Types of Jib Cranes

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 transport loads between any areas within the boom's arc of rotation. Light duty units are utilized within warehouses and factories for loads weighing up to 5 tons. The website BestJibCranes.com features the major types of jib cranes as being either free-standing, wall-mounted or mast mounted.



Free Standing

Free-standing jib cranes could stand alone not requiring support from the building structure. The horizontal boom in this situation is connected to a pivoting vertical column that is solidly anchored to the building floor. This type of jib crane requires a foundation made of either concrete or steel and is able to rotate a full 360 degrees.



Mast-Type

The vertical column on the mast-type jib cranes are supported by pivot points at the bottom and the top. These pivots 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 needed for free-standing units.



Wall Mounted

The wall-mounted jib cranes provide a horizontal boom that is attached to the wall of a building rather than the regular vertical column. These machinery are ideal in places where the full 360 degree rotation is not required and offer up to 200 degrees of rotation.



Depending on how the boom is supported, there are two model varieties. One kind uses a tie rod from above the boom that is attached to the wall. The other variety supports the boom from below by using a cantilever brace that is attached to the wall also.
