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 could move loads between any areas within the boom's arc of rotation. Light duty models are utilized in warehouses and factories for loads weighing up to 5 tons. The BestJibCranes.com website features the major types of jib cranes as being either wall-mounted, mast mounted or free-standing.
Free Standing
The free-standing jib crane units do not require any support from the building structure and are able to stand by themselves. The horizontal boom in this situation is attached to a pivoting vertical column that is anchored firmly to the floor of the building. This kind of jib crane needs a foundation made of either concrete or steel and is able to rotate a full 360 degrees.
Mast-Type
The mast-type jib cranes feature a vertical column that is supported by pivot points at the bottom and the top which are attached to the floor of the building and the overhead steel structure. These jib-cranes provide 360 degrees of rotation with the benefit of not requiring the massive foundation required for free-standing units.
Wall Mounted
The wall-mounted jib cranes offer a horizontal boom that is connected to the building wall as opposed to the typical vertical column. These machine are ideal in areas where the full 360 degree rotation is not required and offer up to 200 degrees of rotation.
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.
