A cement breaker is vital in construction and demolition. It breaks hardened cement structures like concrete floors, walls, and foundations. There are hydraulic and pneumatic types. Hydraulic breakers use pressurized hydraulic fluid for high - impact force, ideal for large - scale work. Pneumatic breakers rely on compressed air, being more portable for smaller jobs or tight spaces. Operators must take safety precautions, wearing helmets, goggles, and gloves. Regular maintenance is key, including checking for leaks, lubricating moving parts, and replacing worn components to ensure performance and longevity.
