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 could transport loads between any areas within the boom's arc of rotation. Light duty models are used within warehouses and factories for loads weighing up to 5 tons. The web site BestJibCranes.com showcases the major types of jib cranes as being either mast mounted, free-standing or wall-mounted.
Free Standing
The free-standing jib crane models do not need any support from the building structure and could stand by themselves. The horizontal boom in this particular case is attached to a pivoting vertical column that is solidly anchored to the floor of the building. This kind of jib crane needs a foundation made of either steel or concrete and could rotate a full three hundred sixty 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 advantage of not needing 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 typical vertical column. These cranes offer a horizontal boom. These machine provide up to two hundred degrees of rotation and are great in places where the full three hundred sixty degree rotation is not needed.
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 variety supports the boom from below by utilizing a cantilever brace that is connected to the wall as well.
A boom truck utilizes a winch to recover heavy items or move materials to areas that are normally inaccessible. Like for example, they are normally utilized to reach the top of a building, maneuvering supplies to a hillside or over a ditch.
Bigger trucks are outfitted with a boom winch that is mounted in the bed of a truck. It is capable of transporting construction items and other equipment from the side of the street to a particular location. There is another boom truck configuration that is outfitted with a cherry picker. This model allows arborists to easily access treetops.
The Vehicle
Terex's Stinger BT 3063 model has a reach of 113-feet and is equipped with both stabilizers and outriggers. 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 trucks are cherry pickers which can lift employees to great heights. Typically, cherry pickers or buckets move employees from the ground up to high areas like for example the sides of buildings, treetops, up utility poles or for fire department rescue and firefighting.
Location
The boom platform could be 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. Larger booms require outriggers which horizontally extend from the truck in order to stabilize and level out the crane in 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.
