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 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 in warehouses and factories for loads weighing as much as 5 tons. The BestJibCranes.com website features the major kinds of jib cranes as being either mast mounted, free-standing or wall-mounted.
Free Standing
Free-standing jib cranes are able to stand alone not requiring support from the building structure. The horizontal boom in this case is connected to a pivoting vertical column that is anchored solidly to the floor of the building. This kind of jib crane requires a foundation made of either steel or concrete and is able to rotate a full 360 degrees.
Mast-Type
The mast-type jib cranes feature a vertical column that is supported by pivot points at the bottom and the top which are connected to the building floor and the overhead steel structure. These jib-cranes provide 360 degrees of rotation with the benefit of not needing 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 normal vertical column. These machinery are great in areas where the full 360 degree rotation is not needed and offer up to 200 degrees of rotation.
Depending on how the boom is supported, there are two model varieties. One kind uses a tie rod from above the boom that is attached to the wall. The other kind supports the boom from below by utilizing a cantilever brace which is also attached to the wall.
