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 which measures up to twenty feet long. Jib cranes can move 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 web site 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 could stand by themselves. The horizontal boom in this specific situation is attached to a pivoting vertical column which is anchored firmly to the building floor. This kind of jib crane needs a foundation made of either steel or concrete and can rotate a full three hundred sixty degrees. Mast-Type The vertical column on the mast-type jib cranes are supported by pivot points at the top and the bottom. These pivots 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 needed for free-standing units. Wall Mounted The wall-mounted jib cranes provide a horizontal boom that is connected to the building wall rather than the typical vertical column. These machine offer up to 200 degrees of rotation and are ideal in areas where the full three hundred sixty degree rotation is not needed. There are two model varieties, depending on how the boom is supported. One of the types uses a tie rod that is attached from above the wall to the boom. The other kind supports the boom from below by using a cantilever brace which is also connected to the wall. A boom truck utilizes a winch to recover heavy things or move supplies to places which are normally inaccessible. Like for example, they are commonly utilized to reach the top of a building, maneuvering supplies to a hillside or over a ditch. A large truck is equipped with a boom winch. This is mounted in the truck's bed and then it is capable of moving construction things and other equipment from street-side to a particular location. There is another boom truck configuration that is outfitted with a cherry picker. This model allows arborists to access treetops easily. The Vehicle The Stinger BT 3063 model has a 113-foot reach and is equipped with stabilizers and outriggers. A boom truck can range from an aerial work platform which is moved by a hydraulic lifting mechanism 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 to suit the specific requirements of the buyer. Cherry Picker Bucket booms or cherry pickers allow employees to reach excellent heights. Normally, buckets or cherry pickers transport workers from the ground up to high places like for instance treetops, the sides of a building, up utility poles or for firefighting and fire department rescue. Location The platform on the boom is 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 horizontally extend from the truck in order to stabilize and level out the crane in its operation. Controls A cab-over-engine model boom truck has a control cluster responsible for moving the boom situated in the cab. It is normally a panel in the boom itself on the side of the bed.
