On the morning of November 20, 2010, the 200,000th gearbox HW15710L (aluminum alloy housing) of China National Heavy Duty Truck Transmission Department was grandly rolled off the assembly line. Hu Youbin and Sun Zhenyu, models of the gearbox department, unveiled colorful silk for this significant gearbox.
From April 9, 2007, the first product successfully went offline and the 100,000th gearbox was assembled. The transmission department took 31 months, and the second 100,000 units successfully took off for only one year. In 20 days, the speed at which China's heavy-duty trucks developed by leaps and bounds was demonstrated.
