Boom deflection is a phenomenon that occurs when a crane is lifting a load and its boom appears to be bending. All booms have this ability to flex so that they can absorb the loading forces that come from lifting a heavy weight.
Boom deflection happens to all cranes, both hydraulic and lattice boom. Even though it’s a normal result of lifting, there still must be safety precautions and awareness. Let’s go over what you need to be aware of for boom deflection during your lifts:
Every crane has a specified safe working load defined in the load chart. As a general safety guideline, be sure to check each crane’s load capacity before any operation begins.
