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 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 utilized in warehouses and factories for loads weighing as much as 5 tons. The BestJibCranes.com web site features the major jib crane models as being either mast mounted, free-standing or wall-mounted.
Free Standing
Free-standing jib cranes could stand alone not needing support from the building structure. The horizontal boom in this specific situation is attached to a pivoting vertical column that is solidly anchored to the floor of the building. This kind of jib crane could 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 which is supported by pivot points at the bottom and the top which are connected 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
Wall mounted jib cranes are attached to the wall of the building rather than supporting a regular vertical column. These cranes offer a horizontal boom. These machine offer up to 200 degrees of rotation and are ideal in areas where the full 360 degree rotation is not required.
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 variety supports the boom from below by using a cantilever brace that is connected to the wall as well.
