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 are able to transport loads between any areas within the boom's arc of rotation. Light duty units are used in warehouses and factories for loads weighing up to 5 tons. The website BestJibCranes.com features the major types of jib cranes as being either free-standing, wall-mounted or mast mounted. Free Standing The free-standing jib crane models do not require any support from the building structure and can stand by themselves. The horizontal boom in this situation is attached to a pivoting vertical column that is anchored solidly to the floor of the building. This kind of jib crane could rotate a full three hundred sixty degrees and requires a foundation made of either steel or concrete. 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 floor of the building and the overhead steel structure. These jib-cranes provide three hundred sixty degrees of rotation with the advantage of not requiring the massive foundation needed for free-standing units. Wall Mounted Wall mounted jib cranes are connected to the building wall instead of supporting a normal vertical column. These cranes provide a horizontal boom. These equipments are great in places where the full 360 degree rotation is not needed and offer up to 200 degrees of rotation. Depending on how the boom is supported, there are two model varieties. One type uses a tie rod from above the boom which is attached to the wall. The other type supports the boom from below by using a cantilever brace that is attached to the wall too. A boom truck utilizes a winch to recover heavy things or transport supplies to places which are normally not accessible. For example, they are normally utilized maneuvering supplies to a hillside or over a ditch 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 particular place. There is another boom truck design that is equipped with a cherry picker. This version enables arborists to easily access treetops. The Vehicle The Stinger BT 3063 model has a 113-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 modified boom lift made for a specific buyer's needs. Cherry Picker Bucket booms or cherry pickers enable employees to reach excellent heights. Usually, cherry pickers or buckets move workers from the ground up to high areas like treetops, the sides of a building, for firefighting and fire department rescue or up utility poles. Location The boom platform could be operated by remote from the truck'[s cab. Either the boom is mounted on a separate trailer or on the bed of a big truck. Larger booms need outriggers that extend horizontally from the truck in order to stabilize and level out the crane during its operation. Controls A cab-over-engine model boom truck has a control cluster responsible for moving the boom situated inside of the cab. It is often a panel in the boom itself on the side of the bed.
