A jib crane is a type of crane where a horizontal member (jib or boom), supporting a moveable hoist, is fixed to a wall or to a floor-mounted pillar. Jib cranes are used in industrial premises and on military vehicles.ormally a crane with a hinged jib will tend to have its hook also move up and down as the jib moves (or luffs). A level luffing crane is a crane of this common design, but with an extra mechanism to keep the hook level when luffing.
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.he 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.
