Jib Crane Types
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 twenty feet long. Jib cranes are able to transport loads between any areas within the boom's arc of rotation. Light duty models are utilized within warehouses and factories for loads weighing up to 5 tons. The BestJibCranes.com website showcases the major kinds of jib cranes as being either wall-mounted, mast mounted or free-standing.
Free Standing
Free-standing jib cranes can stand alone not requiring support from the building structure. The horizontal boom in this specific situation is connected to a pivoting vertical column which is anchored firmly to the floor of the building. This type of jib crane is able to rotate a full three hundred sixty degrees and requires a foundation made of either concrete or steel.
Mast-Type
The vertical column on the mast-type jib cranes are supported by pivot points at the top and the bottom. These pivots are attached to the floor of the building and the overhead steel structure. These jib-cranes provide 360 degrees of rotation with the advantage of not requiring the massive foundation required 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 offer a horizontal boom. These machinery are great in places where the full three hundred sixty degree rotation is not needed and provide 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 that is connected to the wall. The other kind supports the boom from below by utilizing a cantilever brace that is also attached to the wall.
A boom truck utilizes a winch to recover heavy things or transport materials to areas that are usually not accessible. Like for instance, they are normally used to reach the top of a building, maneuvering supplies over a ditch or to a hillside.
Bigger trucks are outfitted with a boom winch that is mounted in the truck's bed. It is capable of transporting construction items and other equipment from the side of the street to a certain location. There is one more boom truck configuration which is outfitted with a cherry picker. This version allows arborists to easily access treetops.
The Vehicle
The Stinger BT 3063 model has a one hundred thirteen-foot reach and is outfitted with outriggers and stabilizers. 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 modified boom lift made to suit the specific requirements of the buyer.
Cherry Picker
Bucket trucks are cherry pickers which could lift workers to great heights. Typically, buckets or cherry pickers transport employees from the ground up to high areas like the sides of buildings, treetops, 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 big truck or on a separate trailer. Booms that are larger need outriggers that horizontally extend from the truck so as to stabilize and level out the crane throughout its operation.
Controls
A cab-over-engine model boom truck has a control cluster responsible for moving the boom located in the cab. It is often a panel in the boom itself on the side of the bed.
