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 twenty feet long. Jib cranes can move 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 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 situation is attached to a pivoting vertical column which is anchored firmly 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 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 connected to the building floor and the overhead steel structure. These jib-cranes offer 360 degrees of rotation with the advantage of not needing the massive foundation required for free-standing units.
Wall Mounted
Wall mounted jib cranes are connected to the wall of the building instead of supporting a normal vertical column. These cranes offer a horizontal boom. These machine are great in places where the full three hundred sixty degree rotation is not needed and offer up to two hundred degrees of rotation.
Depending on how the boom is supported, there are two model varieties. One kind utilizes a tie rod from above the boom that is connected to the wall. The other kind supports the boom from below by utilizing a cantilever brace that is also connected to the wall.
To recover heavy things or to move supplies to places and areas that are not usually accessible, boom trucks will utilize a winch. For instance, they are commonly utilized maneuvering supplies over a ditch or to a hillside or to reach the top of a building.
Bigger trucks are outfitted with a boom winch that is mounted in the truck's bed. It is capable of moving 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 easily access treetops.
The Vehicle
The Stinger BT 3063 model has a one hundred thirteen-foot reach and is outfitted with outriggers and stabilizers. A boom truck could vary 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 to meet the specific needs of the buyer.
Cherry Picker
Cherry pickers or bucket booms allow employees to reach excellent heights. Usually, cherry pickers or buckets transport employees from the ground up to high places like for instance treetops, the sides of a building, for firefighting and fire department rescue or up utility poles.
Location
The platform on the boom is operated by remote from the truck's cab. Either the boom is mounted on the bed of a large truck or on a separate trailer. Booms that are larger require outriggers which extend horizontally from the truck so as to level out and stabilize the crane during its operation.
Controls
This model of boom truck has a cab-over-engine which has a control cluster which can move the boom from inside the cab. It is normally a panel in the boom itself on the side of the bed.
