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 transport loads between any areas within the boom's arc of rotation. Light duty units are utilized within factories and warehouses for loads weighing as much as 5 tons. The website BestJibCranes.com showcases the major kinds of jib cranes as being either free-standing, wall-mounted or mast mounted.
Free Standing
The free-standing jib crane models do not require any support from the building structure and could stand by themselves. The horizontal boom in this case is connected to a pivoting vertical column that is solidly anchored to the floor of the building. This kind of jib crane requires a foundation made of either steel or concrete and can rotate a full 360 degrees.
Mast-Type
The vertical column on the mast-type jib cranes are supported by pivot points at the top and the bottom. These pivots are connected to the floor of the building and the overhead steel structure. These jib-cranes offer 360 degrees of rotation with the benefit of not needing the massive foundation needed for free-standing units.
Wall Mounted
The wall-mounted jib cranes offer a horizontal boom which is attached to the building wall as opposed to the regular vertical column. These machinery provide up to 200 degrees of rotation and are great in areas where the full 360 degree rotation is not required.
Depending on how the boom is supported, there are two model varieties. One type 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 attached to the wall too.
