Jib Crane Types
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 can transport loads between any areas within the boom's arc of rotation. Light duty units are utilized in factories and warehouses for loads weighing up to 5 tons. The BestJibCranes.com website showcases the major types of jib cranes 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 particular situation is attached to a pivoting vertical column that is firmly anchored to the building floor. This type of jib crane requires a foundation made of either concrete or steel and is able to rotate a full 360 degrees.
Mast-Type
The mast-type jib cranes feature a vertical column that is supported by pivot points at the bottom and the top that are connected to the floor of the building and the overhead steel structure. These jib-cranes offer 360 degrees of rotation with the benefit of not requiring the massive foundation needed for free-standing units.
Wall Mounted
The wall-mounted jib cranes offer a horizontal boom which is connected to the building wall as opposed to the normal vertical column. These machinery are great in areas where the full three hundred sixty degree rotation is not required and offer 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 which is attached from above the wall to the boom. The other type supports the boom from below by utilizing a cantilever brace which is also attached to the wall.
To recover heavy things or to move supplies to areas and places that are not usually accessible, boom trucks would use a winch. For instance, they are usually used to reach the top of a building, maneuvering materials to a hillside or over a ditch.
A huge truck is outfitted with a boom winch. This is mounted in the truck's bed and then it is capable of transporting construction things and other equipment from street-side to a particular location. There is a different boom truck design that is outfitted with a cherry picker. This model enables arborists to access treetops easily.
The Vehicle
Terex's Stinger BT 3063 model has a reach of one hundred thirteen-feet and is equipped with both stabilizers and outriggers. A boom truck can range from an aerial work platform that 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
Cherry pickers or bucket booms enable workers to reach excellent heights. Normally, cherry pickers or buckets transport workers from the ground up to high areas such as treetops, the sides of a building, up utility poles or for fire department rescue and firefighting.
Location
The platform on the boom is operated by remote from the truck's cab. Either the boom is mounted on the bed of a large truck or on a separate trailer. Larger booms require outriggers that horizontally extend from the truck so as to level out and stabilize the crane during its use.
Controls
A cab-over-engine model boom truck has a control cluster capable of moving the boom situated inside of the cab. It is often a panel in the boom itself on the side of the bed.
