Jib Crane Types
Jib cranes are made up of a trolley hoist on a horizontal load-bearing boom. This boom is connected to a pivoting vertical member and up to twenty feet long. Jib cranes are able to transport loads between any areas within the boom's arc of rotation. Light duty units are used inside warehouses and factories for loads weighing as much as 5 tons. The website BestJibCranes.com features the major kinds of jib cranes as being either free-standing, wall-mounted or mast mounted.
Free Standing
Free-standing jib cranes could stand alone not requiring support from the building structure. The horizontal boom in this situation is connected to a pivoting vertical column that is anchored firmly to the building floor. This type of jib crane is able to rotate a full three hundred sixty degrees and needs a foundation made of either steel or concrete.
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 building floor and the overhead steel structure. These jib-cranes offer three hundred sixty degrees of rotation with the advantage of not needing the massive foundation needed for free-standing units.
Wall Mounted
The wall-mounted jib cranes provide a horizontal boom that is connected to the building wall rather than the typical vertical column. These machine provide up to two hundred degrees of rotation and are great in areas where the full 360 degree rotation is not needed.
There are two model varieties, depending on how the boom is supported. One of the types uses a tie rod that is connected from above the wall to the boom. The other kind supports the boom from below by utilizing a cantilever brace which is also attached to the wall.
To recover heavy things or to transport supplies to areas and places that are not normally accessible, boom trucks would use a winch. Like for instance, they are usually used maneuvering materials to a hillside or over a ditch or to reach the top of a building.
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 specific place. There is a different boom truck design which is equipped with a cherry picker. This model 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 stabilizers and outriggers. A boom truck can range 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 made to suit the specific requirements of the buyer.
Cherry Picker
Bucket trucks are cherry pickers which can raise employees to great heights. Typically, cherry pickers or buckets transport employees from the ground up to high areas like for example treetops, the sides of a building, up utility poles or for fire department rescue and firefighting.
Location
The boom platform is able to be 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 which are bigger require outriggers that horizontally extend from the truck so as to level out and stabilize the crane throughout its operation.
Controls
A cab-over-engine model boom truck has a control cluster capable of moving the boom situated inside of the cab. It is normally a panel in the boom itself on the side of the bed.
