What Is a Jib Crane

What is a Jib crane? This and several further frequently asked queries are answered in this publication.
To begin it is wise to be aware of the other names to which the Jib crane QTZ160 Tower Cranes is often known as; they are; swing jib, pillar jib or slewing jib. This is a type of crane utilised for lifting and moving hefty loads and consists of the primary supporting upright steel beam with a further steel beam cantilevered out from this with a smaller under or over brace piece of steel for additional strength and stability. The vertical steel beam is attached to a stable foundation, like a wall, pillar or floor, which can take the weight of the load. The horizontal beam is termed the arm or boom and this slews through an arc of various degrees enabling simple movement of your load, this is often either manual or powered. The Jib's arm is also where other devices are attached to raise the loads, these tools could be some type of hoist and beam clamp or trolley arrangement.
Frequently additional pieces of lifting equipment are attached on to the jib arm by the use of a beam clamp or perhaps a beam trolley which can either be manually pulled over the beam or electrically driven; this allows extra movement of the load. Tools mostly used with a jib crane, include electric or manual hoists, chain blocks, or lever hoists, though there are other equipment which may also QTZ125A Tower Cranes be used, for example a lifting magnet.
Now allow us to examine the actual lifting and moving of the load; firstly the lifting device selected (i.e. hoist) needs to be fixed on to the Jib arm, this must then be moved into position straight above the load to be lifted. The load will typically be harnessed in some kind of sling, either a webbing or chain sling. The lifting hoist's chain must then be lowered down so the sling around the load may be fitted, the lift may now commence, gradually to start to make sure it is evenly balanced. As soon as it is secure and clear of the ground...
