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 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 in warehouses and factories for loads weighing as much as 5 tons. The BestJibCranes.com web site features the major jib crane models as being either mast mounted, free-standing or wall-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 solidly anchored to the floor of the building. This type of jib crane requires a foundation made of either steel or concrete and can rotate a full 360 degrees. 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 connected to the floor of the building and the overhead steel structure. These jib-cranes offer three hundred sixty degrees of rotation with the advantage of not needing the massive foundation required for free-standing units. Wall Mounted The wall-mounted jib cranes provide a horizontal boom that is attached to the building wall rather than the regular vertical column. These machine offer up to two hundred degrees of rotation and are ideal in areas 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 uses a tie rod that is connected from above the wall to the boom. The other variety supports the boom from below by using a cantilever brace which is connected to the wall too. A boom truck uses a winch to recover heavy things or transport supplies to places that are usually not accessible. For example, they are commonly used maneuvering materials to a hillside or over a ditch or to reach the top of a building. A large truck is equipped with a boom winch. This is mounted in the truck's bed and then it is capable of transporting construction things and other equipment from street-side to a particular location. There is another boom truck design that is equipped with a cherry picker. This version allows arborists to access treetops easily. The Vehicle Terex's Stinger BT 3063 model has a reach of 113-feet and is equipped with both stabilizers and outriggers. A boom truck could range from an aerial work platform that 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 customized boom lift made for a particular buyer's needs. Cherry Picker Cherry pickers are bucket trucks that could lift workers to great heights. Normally, buckets or cherry pickers move workers from the ground up to high places like for instance the sides of buildings, treetops, 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 a separate trailer or on the bed of a big truck. Booms that are larger need outriggers that horizontally extend 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 capable of moving the boom located inside of the cab. It is often a panel in the boom itself on the side of the bed.
