Kinds of Jib Cranes
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 twenty feet long. Jib cranes can transport loads between any areas within the boom's arc of rotation. Light duty models are utilized in factories and warehouses for loads weighing up to 5 tons. The website BestJibCranes.com showcases the major jib crane types as being either mast mounted, free-standing or wall-mounted.
Free Standing
Free-standing jib cranes are able to stand alone not needing support from the building structure. The horizontal boom in this situation is connected to a pivoting vertical column that is anchored solidly to the building floor. This type of jib crane needs a foundation made of either steel or concrete and can rotate a full 360 degrees.
Mast-Type
The mast-type jib cranes feature a vertical column which is supported by pivot points at the bottom and the top that are attached to the building floor and the overhead steel structure. These jib-cranes offer three hundred sixty degrees of rotation with the benefit of not requiring the massive foundation required for free-standing units.
Wall Mounted
Wall mounted jib cranes are connected to the building wall rather than supporting a regular vertical column. These cranes provide a horizontal boom. These machine are ideal in areas where the full 360 degree rotation is not required and offer up to 200 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 which is attached to the wall. The other type supports the boom from below by utilizing a cantilever brace that is connected to the wall also.
To recover heavy items or to transport supplies to places and areas that are not usually accessible, boom trucks will use a winch. Like for instance, they are commonly used maneuvering materials to a hillside or over a ditch or to reach the top of a building.
A big truck is outfitted with a boom winch. This is mounted in the bed of the truck and then it is capable of transporting construction things and other equipment from street-side to a specific area. There is another boom truck design which 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 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 requirements.
Cherry Picker
Bucket booms or cherry pickers allow employees to reach excellent heights. Normally, cherry pickers or buckets move workers from the ground up to high areas like treetops, the sides of a building, up utility poles or for firefighting and fire department rescue.
Location
The platform on the boom is operated from the truck's cab by remote. Either the boom is mounted on the bed of a big truck or on a separate trailer. Booms that are larger need outriggers which horizontally extend from the truck in order to level out and stabilize the crane in 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.
