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 can move loads between any areas within the boom's arc of rotation. Light duty models are used inside warehouses and factories for loads weighing as much as 5 tons. The website BestJibCranes.com features the major types of jib cranes as being either mast mounted, free-standing or wall-mounted.
Free Standing
Free-standing jib cranes could stand alone not requiring support from the building structure. The horizontal boom in this case is connected to a pivoting vertical column which is solidly anchored to the building floor. This type of jib crane requires a foundation made of either concrete or steel and can rotate a full 360 degrees.
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 offer 360 degrees of rotation with the benefit of not requiring the massive foundation needed for free-standing units.
Wall Mounted
Wall mounted jib cranes are connected to the building wall rather than supporting a regular vertical column. These cranes provide a horizontal boom. These machine are ideal in places where the full 360 degree rotation is not required and offer up to 200 degrees of rotation.
Depending on how the boom is supported, there are two model varieties. One type uses 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 also attached to the wall.
