Jib Crane Models
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 units are utilized inside factories and warehouses for loads weighing up to 5 tons. The BestJibCranes.com website showcases the major jib crane models as being either mast mounted, free-standing or wall-mounted.
Free Standing
Free-standing jib cranes can stand alone not requiring support from the building structure. The horizontal boom in this particular case is connected to a pivoting vertical column that is firmly anchored to the floor of the building. This type of jib crane is able to rotate a full 360 degrees and needs 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 bottom and the top that are attached to the floor of the building and the overhead steel structure. These jib-cranes offer 360 degrees of rotation with the advantage of not requiring the massive foundation required for free-standing units.
Wall Mounted
Wall mounted jib cranes are attached to the wall of the building instead of supporting a normal vertical column. These cranes provide a horizontal boom. These equipments are great in areas where the full 360 degree rotation is not required and provide up to 200 degrees of rotation.
Depending on how the boom is supported, there are two model varieties. One type utilizes a tie rod from above the boom which is connected to the wall. The other variety supports the boom from below by utilizing a cantilever brace which is connected to the wall too.
