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 twenty feet long. Jib cranes are able to transport loads between any areas within the boom's arc of rotation. Light duty units are used in factories and warehouses for loads weighing up to 5 tons. The web site BestJibCranes.com features the major kinds of jib cranes as being either mast mounted, free-standing or wall-mounted. Free Standing The free-standing jib crane units do not require any support from the building structure and can stand by themselves. The horizontal boom in this particular situation is attached to a pivoting vertical column which is anchored firmly to the building floor. This kind of jib crane could rotate a full three hundred sixty degrees and needs a foundation made of either concrete or steel. Mast-Type The mast-type jib cranes feature a vertical column that is supported by pivot points at the top and the bottom that 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 required for free-standing units. Wall Mounted Wall mounted jib cranes are attached to the building wall rather than supporting a typical vertical column. These cranes provide a horizontal boom. These machine offer up to two hundred degrees of rotation and are ideal in places where the full three hundred sixty degree rotation is not required. There are two model varieties, depending on how the boom is supported. One of the kinds utilizes a tie rod that is connected from above the wall to the boom. The other variety supports the boom from below by utilizing a cantilever brace which is also connected to the wall. A boom truck utilizes a winch to recover heavy things or transport materials to areas that are normally not accessible. For example, they are normally used maneuvering materials to a hillside or over a ditch or to reach the top of a building. A huge truck is outfitted with a boom winch. This is mounted in the bed of the truck and then it is capable of moving construction things and other equipment from street-side to a particular location. There is a different boom truck configuration which is outfitted with a cherry picker. This version allows arborists to easily access treetops. The Vehicle The Stinger BT 3063 model has a 113-foot reach and is equipped with stabilizers and outriggers. A boom truck can vary from an aerial work platform which is moved by a hydraulic lifting device that is mounted on the bed, up to a Class 8 tractor-trailer rig with a bucket. It is also possible to have a modified boom lift made for a particular buyer's requirements. Cherry Picker Cherry pickers are bucket trucks which can raise workers to great heights. Usually, cherry pickers or buckets transport employees from the ground up to high places like for example treetops, the sides of a building, for firefighting and fire department rescue or up utility poles. Location The platform on the boom is operated from the truck's cab by remote. Either the boom is mounted on the bed of a big truck or on a separate trailer. Booms which are larger need outriggers which horizontally extend from the truck in order to stabilize and level out the crane during its use. Controls This kind of boom truck has a cab-over-engine which has a control cluster which can move the boom from inside the cab. It is often a panel in the boom itself on the side of the bed.
