What you must know about automatic gear

When parking, shift the gear to P, lock the rotating part with mechanical device, lock the output shaft through the parking brake device inside the transmission, and tighten the hand brake to prevent the car from moving. Only when the car is completely stopped can you switch to P gear. In addition, most automatic transmission models can only be ignited in P or N gear, which can prevent the car from suddenly starting due to the wrong gear.

Product reliability is a breakthrough in China's construction machinery parts industry

At present, the domestic engineering machinery accessory products are uneven in terms of technology, quality and technical level. The product technology is mostly at the middle and low end level, and the echelon of entering the high-end core technology level is undoubtedly a huge challenge for most small and medium-sized enterprises in China. Being eager to break out of the encirclement, it is difficult to find exports, so many domestic enterprises are in a dilemma.
