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 could move loads between any areas within the boom's arc of rotation. Light duty units are used within factories and warehouses for loads weighing up to 5 tons. The BestJibCranes.com website showcases the major jib crane types as being either mast mounted, free-standing or wall-mounted.
Free Standing
Free-standing jib cranes can stand alone not needing support from the building structure. The horizontal boom in this particular situation is connected to a pivoting vertical column that is anchored firmly to the floor of the building. This kind of jib crane could rotate a full 360 degrees and needs a foundation made of either concrete or steel.
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 connected to the building floor and the overhead steel structure. These jib-cranes provide 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 provide a horizontal boom. These machinery provide up to two hundred degrees of rotation and are great in places where the full three hundred sixty degree rotation is not needed.
There are two model varieties, depending on how the boom is supported. One of the kinds 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 too.
To recover heavy items or to transport supplies to places and areas which are not normally accessible, boom trucks would use a winch. For example, they are commonly used to reach the top of a building, maneuvering supplies to a hillside or over a ditch.
Larger trucks are outfitted 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 place. There is a different boom truck design that is outfitted with a cherry picker. This model allows arborists to easily access treetops.
The Vehicle
The Stinger BT 3063 model has a one hundred thirteen-foot reach and is equipped with outriggers and stabilizers. A boom truck could 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 customized boom lift manufactured for a particular buyer's requirements.
Cherry Picker
Bucket booms or cherry pickers allow workers to reach excellent heights. Normally, buckets or cherry pickers move employees from the ground up to high areas like for instance the sides of buildings, treetops, for fire department and firefighting 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 a separate trailer or on the bed of a large truck. Booms which are bigger need outriggers which horizontally extend from the truck so as to stabilize and level out the crane during its use.
Controls
This type 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.
