Jib Crane Types 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 can move loads between any areas within the boom's arc of rotation. Light duty models are used in factories and warehouses for loads weighing up to 5 tons. The website BestJibCranes.com showcases the major jib crane types as being either mast mounted, free-standing or wall-mounted. Free Standing Free-standing jib cranes could stand alone not requiring support from the building structure. The horizontal boom in this specific situation is connected to a pivoting vertical column which is solidly anchored to the building floor. This type of jib crane could rotate a full three hundred sixty degrees and requires a foundation made of either concrete or steel. Mast-Type The vertical column on the mast-type jib cranes are supported by pivot points at the bottom and the top. These pivots are attached to the floor of the building and the overhead steel structure. These jib-cranes provide 360 degrees of rotation with the benefit of not requiring the massive foundation required for free-standing units. Wall Mounted The wall-mounted jib cranes offer a horizontal boom that is connected to the building wall rather than the regular vertical column. These machinery are ideal in areas where the full three hundred sixty degree rotation is not needed and provide up to two hundred degrees of rotation. Depending on how the boom is supported, there are two model varieties. One type utilizes a tie rod from above the boom which is attached to the wall. The other kind supports the boom from below by using a cantilever brace which is also attached to the wall. A boom truck utilizes a winch to recover heavy items or move materials to places which are usually not accessible. Like for instance, they are normally used maneuvering materials to a hillside or over a ditch or to reach the top of a building. Bigger trucks are equipped with a boom winch that is mounted in the bed of a truck. It is capable of transporting construction things and other equipment from the side of the street to a particular place. There is another boom truck design that is equipped 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 equipped 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 customized boom lift manufactured to suit the specific needs of the buyer. Cherry Picker Cherry pickers are bucket trucks that can raise workers to great heights. Normally, cherry pickers or buckets move employees from the ground up to high places like treetops, the sides of a building, 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 large truck or on a separate trailer. Booms which are bigger require outriggers that horizontally extend from the truck so as to level out and stabilize the crane throughout its operation. Controls A cab-over-engine model boom truck has a control cluster capable of moving the boom located in the cab. It is usually a panel in the boom itself on the side of the bed.
