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 move loads between any areas within the boom's arc of rotation. Light duty models are utilized within factories and warehouses for loads weighing up to 5 tons. The BestJibCranes.com website showcases the major kinds of jib cranes as being either mast mounted, free-standing or wall-mounted.
Free Standing
The free-standing jib crane units do not need any support from the building structure and can stand by themselves. The horizontal boom in this particular case is connected to a pivoting vertical column that is anchored firmly to the floor of the building. This type of jib crane can rotate a full 360 degrees and needs a foundation made of either concrete or steel.
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 attached to the building floor and the overhead steel structure. These jib-cranes offer 360 degrees of rotation with the advantage of not requiring the massive foundation needed for free-standing units.
Wall Mounted
The wall-mounted jib cranes offer a horizontal boom which is connected to the building wall rather than the regular vertical column. These equipments 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 type utilizes a tie rod from above the boom that is connected to the wall. The other variety supports the boom from below by utilizing a cantilever brace that is also connected to the wall.
