Types of Jib Cranes
The trolley hoist on a horizontal load-bearing boom are key features on Jib cranes. The boom is secured to a vertical mast that measures 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 within warehouses and factories for loads weighing up to 5 tons. The BestJibCranes.com website showcases the major jib crane types as being either wall-mounted, mast mounted or free-standing.
Free Standing
Free-standing jib cranes are able to stand alone not requiring support from the building structure. The horizontal boom in this specific case is attached to a pivoting vertical column which is anchored solidly to the building floor. This type of jib crane needs a foundation made of either concrete or steel and can rotate a full three hundred sixty degrees.
Mast-Type
The mast-type jib cranes feature a vertical column which is supported by pivot points at the top and the bottom that are attached to the floor of the building and the overhead steel structure. These jib-cranes offer 360 degrees of rotation with the advantage of not requiring the massive foundation required for free-standing units.
Wall Mounted
The wall-mounted jib cranes provide a horizontal boom which is connected to the building wall rather than the regular vertical column. These machine are great in areas where the full three hundred sixty degree rotation is not required and provide up to 200 degrees of rotation.
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 utilizing a cantilever brace which is attached to the wall also.
A boom truck utilizes a winch to recover heavy things or transport supplies to places that are normally inaccessible. For instance, they are normally used maneuvering materials over a ditch or to a hillside or to reach the top of a building.
Bigger trucks are equipped with a boom winch which is mounted in the bed of a truck. It is capable of moving construction things and other equipment from the side of the street to a particular location. There is one more boom truck configuration that is equipped with a cherry picker. This model allows arborists to access treetops easily.
The Vehicle
The Stinger BT 3063 model has a one hundred thirteen-foot reach and is equipped with outriggers and stabilizers. A boom truck can range from an aerial work platform that 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 for a specific buyer's needs.
Cherry Picker
Cherry pickers are bucket trucks that could raise employees to great heights. Normally, cherry pickers or buckets move workers from the ground up to high areas like treetops, the sides of a building, for fire department and firefighting or up utility poles.
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. Larger booms require outriggers which extend horizontally from the truck so as to level out and stabilize the crane in its use.
Controls
This model of boom truck has a cab-over-engine that has a control cluster that can move the boom from inside the cab. It is normally a panel in the boom itself on the side of the bed.
