In earthwork, hoisting and slope construction scenarios, the overall counterweight design directly determines machinery stability and safety. Many overseas purchasers only compare horsepower and tonnage, neglecting the importance of counterweight ratio, material and installation structure, which easily causes body tilt, slipping and rollover risks on complex sites. A scientific counterweight design is precisely matched according to body size, hydraulic output and working load, balancing flexibility and heavy-duty stability. Insufficient counterweight leads to head tilting and imbalance during overload operation; excessive counterweight increases fuel consumption and reduces walking flexibility. For overseas engineering and farm buyers, condition-matched counterweight structure improves operation safety, reduces accidents and equipment wear, and ensures long-term efficient work.
