Jib Crane Types
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 are able to move loads between any areas within the boom's arc of rotation. Light duty units are used inside factories and warehouses for loads weighing as much as 5 tons. The BestJibCranes.com website showcases the major types of jib cranes as being either free-standing, wall-mounted or mast mounted.
Free Standing
Free-standing jib cranes can stand alone not needing support from the building structure. The horizontal boom in this situation is connected to a pivoting vertical column that is anchored firmly to the floor of the building. This type of jib crane needs a foundation made of either concrete or steel 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 bottom and the top. 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
Wall mounted jib cranes are connected to the wall of the building instead of supporting a normal vertical column. These cranes offer a horizontal boom. These equipments provide up to 200 degrees of rotation and are great 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 which is attached to the wall. The other kind supports the boom from below by utilizing a cantilever brace that is connected to the wall as well.
