Types 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 20 feet long. Jib cranes are able to move loads between any areas within the boom's arc of rotation. Light duty models are utilized inside warehouses and factories for loads weighing up to 5 tons. The BestJibCranes.com web site features the major kinds of jib cranes as being either free-standing, wall-mounted or mast mounted.
Free Standing
The free-standing jib crane units do not require any support from the building structure and can stand by themselves. The horizontal boom in this specific situation is attached to a pivoting vertical column that is anchored solidly to the building floor. This kind of jib crane needs a foundation made of either steel or concrete and is able to rotate a full 360 degrees.
Mast-Type
The mast-type jib cranes feature a vertical column which is supported by pivot points at the top and the bottom that are attached to the building floor and the overhead steel structure. These jib-cranes offer 360 degrees of rotation with the advantage of not needing 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 normal vertical column. These cranes offer a horizontal boom. These equipments 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 type uses a tie rod from above the boom which is connected to the wall. The other kind supports the boom from below by using a cantilever brace that is connected to the wall as well.
A boom truck uses a winch to recover heavy things or transport supplies to areas that are typically not accessible. Like for instance, they are normally utilized to reach the top of a building, maneuvering materials to a hillside or over a ditch.
A big truck is outfitted with a boom winch. This is mounted in the bed of the truck and then it is capable of moving construction items and other equipment from street-side to a particular area. There is another boom truck design that is equipped with a cherry picker. This version enables arborists to easily access treetops.
The Vehicle
Terex's Stinger BT 3063 model has a reach of one hundred thirteen-feet and is equipped with both 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 meet the specific needs of the buyer.
Cherry Picker
Bucket booms or cherry pickers enable employees to reach excellent heights. Normally, buckets or cherry pickers move employees from the ground up to high places like 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 a separate trailer or on the bed of a big truck. Bigger booms need outriggers which extend horizontally from the truck in order to level out and stabilize the crane throughout its use.
Controls
A cab-over-engine model boom truck has a control cluster capable of moving the boom located in the cab. It is often a panel in the boom itself on the side of the bed.
