Kinds of Jib Cranes Jib cranes are made up of a trolley hoist on a horizontal load-bearing boom. This boom is connected to a pivoting vertical member and up to 20 feet long. Jib cranes could transport loads between any areas within the boom's arc of rotation. Light duty units are used in factories and warehouses for loads weighing as much as 5 tons. The website BestJibCranes.com showcases the major types of jib cranes as being either free-standing, wall-mounted or mast mounted. Free Standing Free-standing jib cranes could stand alone not requiring support from the building structure. The horizontal boom in this case is attached to a pivoting vertical column which is firmly anchored to the floor of the building. This type of jib crane needs a foundation made of either concrete or steel and is able to 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 bottom and the top. 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 advantage of not needing the massive foundation required for free-standing units. Wall Mounted The wall-mounted jib cranes offer a horizontal boom which is connected to the wall of a building rather than the normal vertical column. These machinery provide up to two hundred degrees of rotation and are ideal in areas where the full three hundred sixty degree rotation is not needed. Depending on how the boom is supported, there are two model varieties. One kind uses a tie rod from above the boom that is attached to the wall. The other type supports the boom from below by utilizing a cantilever brace that is attached to the wall as well. A boom truck utilizes a winch to recover heavy things or move materials to areas which are normally inaccessible. Like for instance, they are usually utilized maneuvering materials to a hillside or over a ditch or to reach the top of a building. A huge truck is equipped with a boom winch. This is mounted in the truck's bed and then it is capable of moving construction items and other equipment from street-side to a particular place. There is another boom truck design which is outfitted with a cherry picker. This version allows arborists to access treetops easily. The Vehicle Terex's Stinger BT 3063 model has a reach of one hundred thirteen-feet and is outfitted with both outriggers and stabilizers. 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 modified boom lift made to meet the particular needs of the buyer. Cherry Picker Cherry pickers or bucket booms enable workers to reach excellent heights. Typically, buckets or cherry pickers transport workers from the ground up to high places like treetops, the sides of a building, up utility poles or for fire department rescue and firefighting. 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 large truck. Booms that are larger require outriggers that horizontally extend from the truck so as to level out and stabilize the crane in its operation. Controls This type of boom truck has a cab-over-engine which has a control cluster that can move the boom from inside the cab. It is usually a panel in the boom itself on the side of the bed.
