Kinds 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 that measures up to 20 feet long. Jib cranes could move loads between any areas within the boom's arc of rotation. Light duty models are used within warehouses and factories for loads weighing as much as 5 tons. The BestJibCranes.com website showcases the major kinds of jib cranes as being either free-standing, wall-mounted or mast mounted.
Free Standing
Free-standing jib cranes could stand alone not needing support from the building structure. The horizontal boom in this situation is attached to a pivoting vertical column that is anchored firmly to the building floor. This type of jib crane needs 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 bottom and the top which 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 needed 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.
There are two model varieties, depending on how the boom is supported. One of the kinds utilizes a tie rod which is connected from above the wall to the boom. The other kind supports the boom from below by using a cantilever brace which is also connected to the wall.
