The term ‘JIB Crane’ refers to cranes which feature a rotating arm with a lifting device supported from it.
JIB Cranes, otherwise known as swing cranes or a Swing JIB, are one of the most simple and common types of crane used. They are widely used amongst industrial premises and are a very important piece of equipment due to their versatility and cost effectiveness, as well as the fact that they increase safety in workplaces and reduce the risk of injury.
The simple structure of a swing JIB has three main components: arm / boom / jib, trolleys and the lifting device. Floor mounted jib cranes also feature a vertical column to support the arm. Typical lifting devices include electric chain hoists, pneumatic chain hoists, manual chain hoists or bespoke lifting systems.
The arm, boom (or JIB as it is sometimes called) provides horizontal movement of the trolley, which supports the lifting device and the weight which is being lifted. The jib arm rotates to about an axis to give radial movement. This rotation can be limited using adjustable stops, but the standard slew angle is 270 – 300 degrees. The arms can be manufactured using standard H beam section or profile tracking depending on the customer requirements. Lightweight aluminium jib cranes are also available for light duty applications such as assembly processes.
The trolley slides horizontally across the boom and is connected to the lifting device, usually an electric chain hoist. This enables you to easily move the lifting device along the beam to complete the lifting operation.
Depending on the application and the customer requirement, there are many different types of jib crane available:
