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 could transport loads between any areas within the boom's arc of rotation. Light duty units are used inside warehouses and factories for loads weighing as much as 5 tons. The BestJibCranes.com website showcases the major jib crane types as being either wall-mounted, mast mounted or free-standing. Free Standing The free-standing jib crane units do not need 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 that is solidly anchored to the building floor. This kind of jib crane could rotate a full three hundred sixty degrees and requires 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 which are attached to the building floor and the overhead steel structure. These jib-cranes offer three hundred sixty degrees of rotation with the benefit of not needing the massive foundation required for free-standing units. Wall Mounted The wall-mounted jib cranes offer a horizontal boom which is attached to the building wall rather than the regular vertical column. These machinery are ideal in places where the full 360 degree rotation is not required and provide up to two hundred 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 variety supports the boom from below by utilizing a cantilever brace which is also attached to the wall. A boom truck utilizes a winch to recover heavy items or transport supplies to areas that are normally not accessible. Like for instance, they are normally used maneuvering supplies over a ditch or to a hillside or to reach the top of a building. A large truck is outfitted with a boom winch. This is mounted in the truck's bed and then it is capable of transporting construction items and other equipment from street-side to a specific place. There is a different boom truck configuration that is outfitted with a cherry picker. This version enables arborists to access treetops easily. The Vehicle The Stinger BT 3063 model has a one hundred thirteen-foot reach and is outfitted with outriggers and stabilizers. A boom truck could vary from an aerial work platform which is moved by a hydraulic lifting device which 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 to meet the particular requirements of the buyer. Cherry Picker Cherry pickers or bucket booms enable employees to reach excellent heights. Usually, buckets or cherry pickers move workers from the ground up to high areas like for example the sides of buildings, treetops, up utility poles or for firefighting and fire department rescue. 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 bigger require outriggers which extend horizontally from the truck so as to level out and stabilize the crane in its use. Controls A cab-over-engine model boom truck has a control cluster responsible for moving the boom located in the cab. It is normally a panel in the boom itself on the side of the bed.
