Jib Crane Models
Jib cranes are made up of a trolley hoist on a horizontal load-bearing boom. This boom is attached to a pivoting vertical member and 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 as much as 5 tons. The BestJibCranes.com website showcases the major jib crane models as being either free-standing, wall-mounted or mast mounted.
Free Standing
The free-standing jib crane units do not require any support from the building structure and can stand by themselves. The horizontal boom in this case is attached to a pivoting vertical column that is anchored solidly to the floor of the building. This kind of jib crane requires a foundation made of either steel or concrete 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 connected to the floor of the building and the overhead steel structure. These jib-cranes offer 360 degrees of rotation with the advantage of not requiring the massive foundation needed for free-standing units.
Wall Mounted
The wall-mounted jib cranes offer a horizontal boom that is attached to the building wall rather than the regular vertical column. These machine are great in areas where the full 360 degree rotation is not needed and offer up to 200 degrees of rotation.
Depending on how the boom is supported, there are two model varieties. One type utilizes a tie rod from above the boom which is connected to the wall. The other variety supports the boom from below by utilizing a cantilever brace that is also connected to the wall.
