Cranes are an important part of any type of civil engineering work. Different types of cranes are used on the basis of the amount of weight to be lifted and the area available for movement at the construction site. A jib crane is one such type. It consists of a pillar fixed to the wall or mounted on the floor. The pillar supports a horizontal jib or boom which has a movable hoist. The hoist is used to lift or lower a load with the help of a drum, or lift-wheel, which has a chain or rope wrapped around it. The drum is driven electrically or pneumatically, and can be operated manually. The lifting medium is usually a chain, although it may also be a fiber rope or wire cable. The load is lifted with the help of a lifting hook attached to the lifting medium.
The term "jib crane" covers all the cranes that have a rotating boom attached to a vertical mast and supporting a hoist that operates electrically or pneumatically. Jib cranes are not only used in construction business, but also on commercial and military ships. The most commonly used jib crane is the self-supported, floor mounted type. Jib cranes are extremely important in all kind of lifting processes because it relieves the overhead crane of much work and reduces the waiting time.
