Types 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 models are utilized within warehouses and factories for loads weighing as much as 5 tons. The website BestJibCranes.com features the major types of jib cranes as being either wall-mounted, mast mounted or free-standing.
Free Standing
The free-standing jib crane units do not require any support from the building structure and could stand by themselves. The horizontal boom in this specific situation is attached to a pivoting vertical column that is anchored firmly to the floor of the building. This kind of jib crane can rotate a full 360 degrees and requires a foundation made of either concrete or steel.
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 floor of the building and the overhead steel structure. These jib-cranes provide 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 connected to the wall of a building rather than the regular vertical column. 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 type supports the boom from below by utilizing a cantilever brace that is attached to the wall too.
