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 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 utilized in factories and warehouses for loads weighing up to 5 tons. The website BestJibCranes.com features the major kinds of jib cranes as being either mast mounted, free-standing or wall-mounted.
The free-standing jib crane models do not need any support from the building structure and could stand by themselves. The horizontal boom in this case is connected to a pivoting vertical column that is firmly anchored to the floor of the building. This type of jib crane needs a foundation made of either concrete or steel and is able to rotate a full 360 degrees.
The vertical column on the mast-type jib cranes are supported by pivot points at the bottom and the top. These pivots are connected to the building floor and the overhead steel structure. These jib-cranes offer 360 degrees of rotation with the advantage of not needing the massive foundation required for free-standing units.
Wall mounted jib cranes are connected to the building wall instead of supporting a regular vertical column. These cranes provide a horizontal boom. These equipments offer up to 200 degrees of rotation and are ideal in places where the full 360 degree rotation is not required.
Depending on how the boom is supported, there are two model varieties. One kind utilizes a tie rod from above the boom which is connected to the wall. The other type supports the boom from below by utilizing a cantilever brace that is attached to the wall too.
