By adjusting the length ratio of the excavator's arms and the hydraulic cylinder specifications of the bucket arm, the excavator can be kept unchanged.Under the condition of power matching of the original vehicle, the excavation force is greatly increased; the pressure of the working face is given by increasing the weight of the upper arm and the lower arm to raise the bucket teeth; and the overall structure of the lower arm and the loosener is strengthened to enhance the transmission efficiency of the force so as to achieve the ultimate goal of effectively improving the excavator's destructive force
Suitable working conditions: Shale/sandstone/permafrost weathered limestone and other rocks with moderate or lower strength.
Product advantages: Strong structure, strong excavation, a certain impact, low failure rate, low maintenance cost
