Jib Crane Models
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 can move loads between any areas within the boom's arc of rotation. Light duty models are utilized inside warehouses and factories for loads weighing up to 5 tons. The website BestJibCranes.com showcases 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 needing support from the building structure. The horizontal boom in this case is connected to a pivoting vertical column that is anchored solidly to the floor of the building. This type of jib crane is able to rotate a full 360 degrees and needs a foundation made of either concrete or steel.
Mast-Type
The mast-type jib cranes feature a vertical column which 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 provide a horizontal boom which is connected to the wall of a building rather than the regular vertical column. These machinery are great in places where the full 360 degree rotation is not needed and provide up to 200 degrees of rotation.
There are two model varieties, depending on how the boom is supported. One of the kinds utilizes a tie rod that is attached from above the wall to the boom. The other variety supports the boom from below by utilizing a cantilever brace which is connected to the wall also.
