In our Sims Crane Minute, Bob Berry discusses the dangers of overloading and shock loading of cranes during heavy lifting operations.

As a load is lifted, the force of gravity and weight of the load apply dynamic loads to the crane structure. The boom of the crane is designed to redistribute these loads along the length of the crane, allowing the crane operator to lift heavy objects at great heights and distances.

Flagging, rigging and directly crane rental operations requires comprehensive knowledge of how the crane structure will react when these forces are applied. Attempting to lift objects of unknown weight, or objects secured to the ground, seriously increase the dynamic force applied to the boom of the crane.

Many accidents may be avoided when lifting and removing poles or objects secured in the ground, by first removing the surrounding soil. This will help avoid catastrophic failure of the crane and prevent costly accidents and serious personal injuries.
