Jib Crane Models
Jib cranes are made up of a trolley hoist on a horizontal load-bearing boom. This boom is connected to a pivoting vertical member and up to 20 feet long. Jib cranes can move loads between any areas within the boom's arc of rotation. Light duty units are utilized inside warehouses and factories for loads weighing up to 5 tons. The BestJibCranes.com web site features the major jib crane models as being either free-standing, wall-mounted or mast mounted.
Free Standing
The free-standing jib crane models do not need any support from the building structure and are able to stand by themselves. The horizontal boom in this specific situation is connected to a pivoting vertical column that is solidly anchored to the building floor. This type of jib crane requires a foundation made of either steel or concrete and can rotate a full 360 degrees.
Mast-Type
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 required for free-standing units.
Wall Mounted
The wall-mounted jib cranes provide a horizontal boom that is attached to the wall of a building rather than the normal vertical column. These machine provide up to 200 degrees of rotation and are ideal in places where the full 360 degree rotation is not needed.
Depending on how the boom is supported, there are two model varieties. One kind utilizes a tie rod from above the boom that is connected to the wall. The other kind supports the boom from below by using a cantilever brace which is also attached to the wall.
