① Hydrostatic transmission has high efficiency and a wide range of efficient working conditions, which can save resources and simplify the structure of auxiliary facilities such as heat dissipation and cooling.
② By using a closed circuit combination of variable pump and variable motor, automatic stepless regulation is achieved, and the diesel engine power remains relatively constant, with the highest power utilization rate and good overall operation economy.
③ By using a dual DA control variable system, under composite operating conditions, the diesel engine speed decreases, but the hydraulic system pressure remains constant, thereby preventing a decrease in traction.
④ The overall parameter optimization of the entire machine has been achieved to the greatest extent, enabling it to provide maximum productivity and economic benefits.
