Jib Crane Types
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 units are utilized in warehouses and factories for loads weighing up to 5 tons. The BestJibCranes.com website showcases the major jib crane models as being either wall-mounted, mast mounted or free-standing.
Free-standing jib cranes can stand alone not requiring support from the building structure. The horizontal boom in this case is connected to a pivoting vertical column that is anchored firmly to the building floor. This type of jib crane requires a foundation made of either concrete or steel and is able to rotate a full 360 degrees.
The mast-type jib cranes feature a vertical column which is supported by pivot points at the bottom and the top that are connected to the building floor and the overhead steel structure. These jib-cranes provide 360 degrees of rotation with the benefit of not requiring the massive foundation needed for free-standing units.
The wall-mounted jib cranes offer a horizontal boom that is attached to the wall of a building as opposed to the typical vertical column. These machine are great in areas where the full 360 degree rotation is not required and offer up to 200 degrees of rotation.
Depending on how the boom is supported, there are two model varieties. One kind utilizes a tie rod from above the boom which is attached to the wall. The other variety supports the boom from below by utilizing a cantilever brace which is connected to the wall as well.
