Whether you’re on a commercial construction project or performing tree work, cranes are a critical piece of machinery for work sites. These devices utilize a pulley and cable system to move, lift, and lower heavy materials and equipment. Here is a comprehensive guide to how a crane service works so that you can understand the goings-on at your construction site.

All About Crane Services

Cranes use a combination of simple machines to lift heavy materials and objects. The tallest part of the crane is called the mast; it’s supported by a heavy base to ensure it can lift heavy weights at a greater height. For mobile cranes, the base is typically a rubber-tired or truck carrier.

The slewing unit is located at the top of the mast. It consists of a gear and motor — which are the mechanisms that allow the crane to rotate. The slewing unit also features a jib — or the long horizontal arm equipped with a trolley to carry heavy materials, a short arm that contains the motor, and concrete weights for balance. The pulley and the beam, which acts as a lever, work to multiply the force and lift extremely heavy loads. To achieve horizontal movement, the crane is mounted on a rotating pivot. 

To ensure that the cranes remain stable, regulations are in place that allow a crane to lift only 85 percent of what the load would be for the crane to tip over. A certified operator is also the only professional who should set up, inspect, and operate the crane.
