A jib crane, also known as a derrick or jib crane, is a type of crane that uses a boom to lift and move loads. The boom typically extends beyond the footprint, allowing for a long reach when picking up loads.

The operation of a jib crane is based on a support frame or fixed foundation that supports the vertical loads of the jib and the lifted loads. The jib is attached to a pivot point and can be slewed horizontally to move loads over a specific area.

Jib cranes are used in a variety of industries, including construction, heavy industry, port operations, shipping, oil and gas, mining and construction. They are often used for tasks such as lifting and moving heavy loads on construction sites, loading and unloading ships or assembling large structures.

The advantages of jib cranes lie in their flexibility and reach. The jib allows loads to be placed in hard-to-reach places, which enables them to be used in different environments. They also offer a high load capacity and can lift heavy loads safely and efficiently.

Safety is an essential aspect when using jib cranes. Proper operator training and regular maintenance and inspections are required to prevent accidents and ensure the safe use of the crane.

Overall, jib cranes are versatile lifting devices that are used in various industries to move heavy loads and increase efficiency in construction and industrial projects.
