Definition and Uses of a Jib Crane

A jib crane is a type of crane in which the crane structure swivels around a horizontal axis at the top. The sling is attached to this rotating structure, which is commonly referred to as a "jib," hence the name jib crane. Often, a jib crane is mounted on a trailer or truck so that it can be transported to job sites. Since the jib can rotate horizontally 360 degrees, it can move loads in any direction and place them vertically in any direction. Its height can be altered by extending and contracting the boom. A boom hoist uses similar principles but has a boom that typically extends vertically from a fixed tower structure.

What is a jib crane?

A jib crane is a small lifting device, usually mounted on top of a fixed mast and powered by an electric motor. It is also called jib arm, gib crane, and crane jib.

In this jib crane application, the electric motor drives the geared headgear assembly to raise or lower the load. The headgear assembly is connected to a mechanical arm known as a jib or boom. Jib cranes are good for lifting loads that are 15-60 m (50-200 ft) above the ground. This type of crane is widely used in many industries such as construction, manufacturing, shipbuilding, steel mill, and so on.

A typical jib crane can be fitted with a 360° rotating cab that allows the operator to swing the boom through a complete circle. This type of rotating cab can pivot in only one direction. A jib crane's boom can also be fitted with an electric hoist. The hoist can make it possible for an operator to lift and lower loads by using remote controls from inside the cab.

How is a jib crane different from a gantry crane? 

●    Securing

The clearest contrast between a gantry crane and a jib crane is their mooring. The jib crane uses a solitary shaft for its anchor while the gantry crane uses steel sprinters. The steel sprinters could be mounted on a stacking tower or at the edges of a plant roof.

●    Range of movement

The gantry crane can uphold a lot heavier burdens because of its more noteworthy help. The jib crane just has a solitary post that is dashed into the ground. An excess of weight and the post might force at any point out of the ground by shearing the bolts into equal parts. Gantry cranes can have encased steel sprinters that grasp the top and lower part of their wheels, subsequently holding them set up.

●    Range of Development

A gantry crane is considerably more flexible than a jib crane. The jib crane can turn about its shaft and slide the crane winch to and fro along the supporting bar. Anyway, a gantry crane can slide to and fro along its sprinters and side to side on the supporting shaft. Transport building dockyards use gantry cranes since they can change position effectively, conveying prebuilt segments from the manufacturing plant to the dry dock.

●    Common Uses

Jib cranes are most commonly used to move more modest burdens a brief distance. For instance, the crane on the facade of a horse shelter is a jib crane — it should simply swing out and raise feed packs up to the subsequent floor. Gantry cranes are utilized in production lines, power plants, shipyards, and seaports. Gantry cranes are utilized for weighty articles moved significant distances and over different things.

Where are jib cranes used?

Jib cranes are tower cranes that are stabilized on top of a horizontal arm. Jib cranes are used to work on higher structures or when a structure is too small to accommodate a full-size or crawler crane.

Crane is primarily used in the heavy-duty lifting industry. It is used to lift heavy-duty machinery, construction equipment, and various other machinery that requires vertical lifting, which makes it a perfect choice for all construction sites. In fact, the crane is one of the first heavy machinery that was invented. The principle is to use the mechanical advantage that is available in the arm and its length. This will help to reduce the power that is required to lift a heavy object.

The jib crane uses a boom and a jib, or arm and boom are two main components of a crane. The boom may be vertical or horizontal in nature. Depending on their presence and position at the base, they are categorized as either cantilever or gantry types. The boom usually consists of two main parts, including the upper boom, which is also known as the load arm or main boom, and the lower boom which serves as a support base to the upper boom. The jib typically consists of two parts namely the top or top jib, which is commonly referred to as the main jib, and the bottom or bottom jib. Depending on their direction of rotation, cranes can be either right-handed or left-handed.
