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 that measures up to 20 feet long. Jib cranes can transport 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 website showcases the major types of jib cranes as being either mast mounted, free-standing or wall-mounted.
Free Standing
The free-standing jib crane units do not need any support from the building structure and are able to stand by themselves. The horizontal boom in this specific case is connected to a pivoting vertical column that is solidly anchored to the building floor. This kind of jib crane requires a foundation made of either steel or concrete and could rotate a full 360 degrees.
Mast-Type
The vertical column on the mast-type jib cranes are supported by pivot points at the top and the bottom. 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 advantage of not needing the massive foundation needed for free-standing units.
Wall Mounted
Wall mounted jib cranes are connected to the building wall rather than supporting a typical vertical column. These cranes provide a horizontal boom. These machine provide up to 200 degrees of rotation and are great in places where the full 360 degree rotation is not required.
There are two model varieties, depending on how the boom is supported. One of the kinds uses a tie rod that is connected from above the wall to the boom. The other type supports the boom from below by utilizing a cantilever brace that is also connected to the wall.
