Transmission and torque converter assembly The countershaft power shift transmission features high maturity and reliability. The three-element torque converter ensures the maximum utilize tion of engine power. The drive shaft flanges are of international standard specification and the distribution diameter of the fastening bolts is enlarged to realize super-strong torsion resistance and adapt to high strength and heavy-load continuous operations. Firm and reliable super-strong heavy-duty structural parts. Super-strong structure The finite element analysis technology is applied for structural parts to reduce the stress concentration, eliminate the partial weaknesses, and thoroughly adapt to diversified working conditions. International quality hydraulic and electric units The first-class hydraulic units ensure low pressure loss, less system heating, and high reliability. The international quality hydraulic hoses applied feature high heat and pressure resistance and long life. The hydraulic pipelines adopt double sealing means (DIN standard 24º taper thread + O-ring) to achieve better sealing performance and effectively solve the leakage problem. The harnesses are made of imported quality material and the process layout is optimized to ensure reliable electric circuit system. Convenient Maintenances The framework structure engine hood and the uplift large side doors boast large opening angle and make the checking, repair, and maintenance easier for the engine and radiator. The central fuse case centrally indicates the working status of electric system and eases the maintenances. The independent chamber design for oil return line of hydraulic oil tank guarantees the convenient maintenances.
