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 which measures up to 20 feet long. Jib cranes are able to transport loads between any areas within the boom's arc of rotation. Light duty models are utilized within warehouses and factories for loads weighing up to 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
The free-standing jib crane units do not need any support from the building structure and could stand by themselves. The horizontal boom in this situation is connected to a pivoting vertical column that is firmly anchored to the building floor. This kind of jib crane could 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 that are attached 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 required for free-standing units.
Wall Mounted
The wall-mounted jib cranes offer a horizontal boom that is connected to the building wall rather than the typical vertical column. These machinery provide up to 200 degrees of rotation and are great in areas where the full 360 degree rotation is not required.
Depending on how the boom is supported, there are two model varieties. One kind uses a tie rod from above the boom which is attached to the wall. The other variety supports the boom from below by utilizing a cantilever brace that is also attached to the wall.
