Kinds 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 that measures up to 20 feet long. Jib cranes are able to move loads between any areas within the boom's arc of rotation. Light duty units are utilized within factories and warehouses for loads weighing as much as 5 tons. The BestJibCranes.com website showcases the major jib crane models as being either mast mounted, free-standing or wall-mounted.
Free Standing
The free-standing jib crane models do not require any support from the building structure and could stand by themselves. The horizontal boom in this case is connected to a pivoting vertical column that is anchored firmly to the floor of the building. This kind of jib crane could rotate a full 360 degrees and requires a foundation made of either concrete or steel.
Mast-Type
The mast-type jib cranes feature a vertical column that is supported by pivot points at the top and the bottom that are attached to the floor of the building and the overhead steel structure. These jib-cranes provide 360 degrees of rotation with the advantage of not requiring the massive foundation needed for free-standing units.
Wall Mounted
Wall mounted jib cranes are attached to the wall of the building instead of supporting a typical vertical column. These cranes offer a horizontal boom. These equipments are ideal in areas where the full 360 degree rotation is not required and provide 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 utilizing a cantilever brace which is also connected to the wall.
