Kinds 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 which measures up to twenty feet long. Jib cranes are able to move loads between any areas within the boom's arc of rotation. Light duty units are utilized within warehouses and factories for loads weighing as much as 5 tons. The BestJibCranes.com website showcases the major jib crane types as being either wall-mounted, mast mounted or free-standing.
Free Standing
The free-standing jib crane units do not need any support from the building structure and can stand by themselves. The horizontal boom in this specific situation is connected to a pivoting vertical column that is anchored solidly to the floor of the building. This type of jib crane is able to rotate a full 360 degrees and requires a foundation made of either steel or concrete.
Mast-Type
The mast-type jib cranes feature a vertical column that is supported by pivot points at the top and the bottom which are attached to the floor of the building and the overhead steel structure. These jib-cranes offer three hundred sixty degrees of rotation with the advantage of not requiring the massive foundation needed for free-standing units.
Wall Mounted
Wall mounted jib cranes are attached to the wall of the building instead of supporting a regular vertical column. These cranes provide a horizontal boom. These equipments offer up to two hundred degrees of rotation and are ideal in places where the full three hundred sixty degree rotation is not required.
Depending on how the boom is supported, there are two model varieties. One type uses a tie rod from above the boom which is attached to the wall. The other kind supports the boom from below by using a cantilever brace that is attached to the wall too.
To recover heavy things or to transport supplies to areas and places that are not normally accessible, boom trucks would use a winch. Like for instance, they are normally utilized to reach the top of a building, maneuvering materials to a hillside or over a ditch.
Larger trucks are outfitted with a boom winch that is mounted in the truck's bed. It is capable of moving construction items and other equipment from the side of the street to a certain place. There is one more boom truck design which is outfitted with a cherry picker. This model 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 vary from an aerial work platform which 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 modified boom lift manufactured to meet the particular needs of the buyer.
Cherry Picker
Cherry pickers or bucket booms allow employees to reach excellent heights. Typically, buckets or cherry pickers move employees from the ground up to high areas like for instance treetops, the sides of a building, up utility poles or for firefighting and fire department rescue.
Location
The boom platform is able to be 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. Larger booms require outriggers which extend horizontally from the truck in order to stabilize and level out the crane in its use.
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 normally a panel in the boom itself on the side of the bed.
