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 import ant in all kind of lifting processes because it relieves the overhead crane of much work and reduces the waiting time.

There are three main types of Jib Cranes:
Floor-mounted Type
Wall mounted Type (fixed)
Wall mounted Type (traveling)

Floor Mounted Jib Crane

This is the most commonly used Jib crane.Floor mounted jib crane is a self-supporting jib crane having a vertical mast mounted on a concrete foundation. These types of cranes are generally used to share the load of main cranes. The construction of the crane is as described above. All these cranes can rotate **0 degrees and are manually operated

Wall Mounted Jib Cranes

The Wall Mounted Jib Crane is mounted horizontally on the wall and instead of a vertical shaft has a RCC column bracket mounting.The hoist mechanism is similar to the floor mounted type, but without a vertical boom.The RCC column bracket
allows a maximum rotation of **0 degrees but covers the area near the bracket mounting without obstruction at floor level

Wall Mounted Jib Cranes

The construction of Wall Mounted Jib Cranes(traveling) is similar to that of fixed type with the only difference that the crane is able to cover the lengthwise area near the building columns without obstruction at floor level. The crane's columns
are specially designed and the crane instead of rotating,moves along a runway track suspended along building columns
