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 are able to move loads between any areas within the boom's arc of rotation. Light duty models are used within warehouses and factories for loads weighing up to 5 tons. The BestJibCranes.com web site showcases the major jib crane types as being either mast mounted, free-standing or wall-mounted.
Free Standing
Free-standing jib cranes are able to stand alone not requiring support from the building structure. The horizontal boom in this particular case is connected to a pivoting vertical column which is anchored firmly to the floor of the building. This kind of jib crane can 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 attached to the building floor and the overhead steel structure. These jib-cranes provide 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 instead of supporting a typical vertical column. These cranes offer a horizontal boom. These machine are ideal in places 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 that is attached from above the wall to the boom. The other kind supports the boom from below by utilizing a cantilever brace that is also connected to the wall.
