Jib Crane

Cranes have dramatically developed over the years since they were introduced by the Ancient Greeks thousands of years ago.  In their earliest form cranes were powered by men and/ or pack animal, whilst today modern cranes are often simply operated by workers.  The name comes from the fact that a basic system shared the same characteristics as the bird of the same name, with an outstretched neck (crane post) and long beak (crane arm).   

A crane and lift assistor system are designed to raise and manoeuvre heavy and/ or awkward loads. The lift assistor (electric hoist, air balancer, vacuum lifter or air hoist) actually does the physical lifting, whilst the crane will allow the load to be manoeuvred horizontally within its working envelope.     

A jib crane (also known as a  boom crane) are often regarded as one of the smallest, most versatile type of crane and are found within many factories throughout the world. A jib crane consists of a horizontal arm (also known as a jib or boom) which is usually connected to a floor mounted post, although sometimes the arm can be fixed to a wall or existing steelwork. In most cases the arm will be unrestricted and therefore will allow the operator to push the load round in an arc.  Over the years there have been many variations on the basic jib crane system, most noticeably the articulating jib crane. An articulating jib crane has a joint in the centre of its arm, which allows the load to be easily moved within an area where there is restricted space or obstacles.
