Support foot pad is mainly used to pad at the foot of the support of construction machinery, play a supporting role. The supporting leg plate has higher strength and stiffness, which can reduce the deformation of the supporting plate body under stress, and provide more stable supporting force for the construction machinery, which greatly saves the use cost and improves the working quality, so that it can be used normally under bad environment, and the overload USES ning bend without breaking.支脚垫板主要用于垫在工程机械的支脚下，起支撑作用。支腿垫板具有较高的强度和刚度，进而能够减小受力时垫板本体的变形量，为工程机械提供更加稳定的支撑力，大大节约了使用成本提高了工作质量，使其可在恶劣环境下正常使用，超载使用宁弯而不断裂。
