Many operators overload forklifts to improve handling efficiency. No obvious failures occur in the short term, making potential damage easy to ignore. The rated load of forklifts is a precise safety standard calculated according to overall structural strength, hydraulic bearing capacity and chain tension. Long-term overload operation compresses mast structures, stretches lifting chains and increases hydraulic load, causing structural deformation, chain loosening and hydraulic seal aging. These hidden damages accumulate continuously and eventually lead to cargo sliding, weak lifting and brake failure, shortening equipment life and threatening personnel safety. Abiding by rated load standards is the basic rule for equipment protection and safety risk avoidance.
