Free-Standing Jib Crane – You Might Have Considered The Reasons You Need To Have This..

Cranes form a significant part of most civil engineering projects. Different kinds of cranes are used depending on the weight to be lifted and available area for movement. One type of such cranes is the jib crane.

A jib crane is a kind of crane that utilizes a mounted arm in lifting, moving and lowering materials. The arm, which is mounted in an acute-angle upwards from or perpendicular to some wall or pillar, can rotate across the central axis for any full circle or even a limited arc. These cranes are generally used in industrial sectors, like docks and warehouses, in loading and unloading shipping containers.

The history of Free-Standing Jib Crane goes back to the ancient Greece, when the concept of lifting objects having a mechanical arm was frequently used. On the same note, the Romans later adopted the idea and used it in the making of aqueducts, roads and other engineering structures. Cranes were advanced, but remained identical in designs to the classical ones till the invention from the steam engine as well as the industrial revolution inside the nineteenth century. With the ever growing construction for both sea and land, as well as the increasing demands of shipping companies and complex factories, cranes also created in intricacy and size during this time.

The working principle of jib crane

The fundamental notion of a crane is caused by the mechanical advantage concept. Mechanical advantage refers back to the principle that the machine, just like a pulley, is capable of doing multiplying the force exerted onto it by a given factor. This explains why it’s possible, for instance, for starters man to use a pulley to lift huge thing that would demand a combined force of many men to lift the identical load directly. A crane incorporates a wide range of pulleys with simple machines, like levers and gears, to significantly increase lifting capacity.

In the current jib cranes, robust metal cable is wrapped round the jib strut ends, using the end from the hoist often linked to an electromagnet or hook, while the opposite end is attached to a metallic winch. Whenever you activate the winch, the pulley offers a lifting force that’s comparable to the force applied by the metallic winch. The hoist can move inwards or outwards along the jib length, providing better yet flexibility of motion.

A jib crane is not confined to a set location and may be mounted on a movable chassis to use in military operation or other temporary work sites. Such cranes often focus more on mobility instead of lifting capacity. Outriggers are frequently utilized in mobile jib cranes to ensure they are stable under load. On the other hand, the stationary cranes are generally anchored set up.

Varieties of jib cranes


This type of cranes requires no support to really make it stable while placed on the floor. They come with a sizable foundation base to keep them stable. The base and height from the foundation largely depend on the load to get lifted. The notable benefit from this crane over its counterparts is it doesn’t need a solid structure or wall to back up itself. Furthermore, it provides maximum coverage and span.

Wall mounted

Just like the name suggests, wall mounted cranes are mounted on the walls. It offers optimal lift when fitted closer to the roofs. The coverage with this jib crane is comparable to that relating to other sorts of crane. It has jkyqjq circular shape. It is quite effective in moving materials when the floor is jam-filled with other stuff.

Wall bracket

This crane is similar to its wall mounted counterpart with regards to structure and installation requirement but it’s incorporated using a bracket. This machine offers maximum hoist coverage, making it a competent tool in warehouses and factories. It is capable of swinging loads all-around no matter obstructions and obstacles on the floor.

Mast style

This kind of jib crane is practically similar to the free standing type. The sole difference is that the latter will not require any support to keep it stable. On the other hand, a mast style crane is mounted at the bottom and top but it’s probably the most efficient mobile cranes. It provides maximum lift having a 360-degree rotation.
