Jib Crane Models
The trolley hoist on a horizontal load-bearing boom are key features on Jib cranes. The boom is secured to a vertical mast which measures up to 20 feet long. Jib cranes could 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 web site BestJibCranes.com showcases the major kinds of jib cranes as being either free-standing, wall-mounted or mast mounted.
Free Standing
Free-standing jib cranes could stand alone not requiring support from the building structure. The horizontal boom in this specific situation is connected to a pivoting vertical column which is firmly anchored 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 which is supported by pivot points at the top and the bottom which 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.
Wall Mounted
Wall mounted jib cranes are connected to the building wall rather than supporting a regular vertical column. These cranes provide a horizontal boom. These machinery provide up to 200 degrees of rotation and are ideal in places where the full 360 degree rotation is not required.
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 kind supports the boom from below by using a cantilever brace which is attached to the wall too.
