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 which 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 used 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 need any support from the building structure and are able to stand by themselves. The horizontal boom in this particular situation is attached to a pivoting vertical column that is firmly anchored to the building floor. This type of jib crane needs a foundation made of either concrete or steel and is able to rotate a full 360 degrees.
Mast-Type
The vertical column on the mast-type jib cranes are supported by pivot points at the bottom and the top. These pivots 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
The wall-mounted jib cranes provide a horizontal boom which is connected to the building wall rather than the normal 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.
There are two model varieties, depending on how the boom is supported. One of the types utilizes a tie rod that is connected from above the wall to the boom. The other variety supports the boom from below by utilizing a cantilever brace that is attached to the wall too.
