How Does Jib Crane Design Help in Classification of Cranes
A jib crane is a type of overhead lifting device. The jib crane design is such that it is suitable for a smaller work area for repetitive and unique lifting tasks. They are generally paired with overhead bridge cranes to maximize production. Jib cranes have a simple design and are used to lift weight in a range of 250 pounds to 15 tons. The appealing design of this type of lifting equipment makes it ideal in the production units, mainly because they increase work productivity, reduce workplace injuries and improve safety. Compared to a free standing overhead crane, bridge or gantry cranes, the jib cranes are simple to operate and require less maintenance because most parts of the cranes would not break down or fail. The jib cranes are classified depending upon the function and installation methods. Most common models include: Freestanding jib cranes: These cranes are commonly used indoors and outdoors as well. They can be used under a large bridge crane system or in open areas where they can support various work cells. Outdoor application of these cranes includes marinas or loading docks. Machining and assembly operations, where a series of jib cranes are fixed to be used in conjunction. Foundationless jib cranes: This type of jib cranes are also a type of freestanding jib cranes that are slab mounted and bolted to 6 inches reinforced concrete for indoor use. These cranes can be installed almost anywhere as they do not require any special foundation. These cranes can be easily relocated as they do not require a lot of time for installation Wall-mounted jib cranes: The main advantage of using a wall-mounted system is the space savings it offers, mainly because they are fixed in individual bays, along walls or building support columns or as a supplement to an existing monorail or overhead bridge crane. Articulating jib cranes: Articulating jib cranes have two swivel arms that can lift loads around corners and columns and can reach under machinery and containers. These cranes can be floor, wall or ceiling mounted. The different configuration of the crane allows precise load positioning and spotting loads around obstructions. For heavier duty and more frequent lifts, articulating jib cranes may not be the best choice. Their span is limited as well. Installing a single or a series of jib cranes would not only increase production but increase the safety of the workplace.
