Jib Crane Models
Jib cranes are made up of a trolley hoist on a horizontal load-bearing boom. This boom is attached 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 utilized inside warehouses and factories for loads weighing as much as 5 tons. The BestJibCranes.com web site showcases the major kinds of jib cranes as being either wall-mounted, mast mounted or free-standing.
Free Standing
The free-standing jib crane units 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 firmly anchored to the floor of the building. This type of jib crane requires a foundation made of either steel or concrete and could 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 provide three hundred sixty 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 building wall instead of supporting a typical vertical column. These cranes offer a horizontal boom. These machine are ideal in places where the full three hundred sixty degree rotation is not required and provide up to two hundred degrees of rotation.
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 variety supports the boom from below by utilizing a cantilever brace that is also connected to the wall.
To recover heavy things or to transport materials to places and areas which are not normally accessible, boom trucks will use a winch. For example, they are normally used maneuvering supplies over a ditch or to a hillside or to reach the top of a building.
Larger trucks are equipped with a boom winch which is mounted in the bed of a truck. It is capable of moving construction items and other equipment from the side of the street to a specific place. There is another boom truck configuration 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 stabilizers and outriggers. A boom truck could range from an aerial work platform which is moved by a hydraulic lifting mechanism which 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 manufactured for a specific buyer's requirements.
Cherry Picker
Cherry pickers or bucket booms allow workers to reach excellent heights. Usually, buckets or cherry pickers transport employees from the ground up to high places like for instance treetops, the sides of a building, up utility poles or for fire department rescue and firefighting.
Location
The boom platform is able to be operated from the truck's cab by remote. Either the boom is mounted on the bed of a large truck or on a separate trailer. Bigger booms need outriggers that extend horizontally from the truck so as to stabilize and level out the crane during its operation.
Controls
This kind of boom truck has a cab-over-engine which has a control cluster that could move the boom from inside the cab. It is often a panel in the boom itself on the side of the bed.
