The hybrid technology route in the field of commercial vehicles is being recognized by more and more customers, "ups and downs, uphill and downhill, want to use electric vehicles, insufficient energy" on the use of hybrid dump trucks, at present, Sany hybrid dump trucks have also launched heavy-duty, composite 423 and other models.
1. MixThe combined power dump truck contains the engine of a conventional fuel vehicleforGuaranteed engine"Breathing" is normal, and it is important to maintain the air intake systemLet's introduce it todayAir intakeHow the system is maintained:
1.After every 5,000 kilometers of the vehicle or 3,000 kilometers in harsh areas, the main filter element needs to be maintained, and the dust can be blown clean from the inside to the outside with an air gun [the pressure of the air gun cannot be higher than 4bar (400kpa), otherwise it may cause damage to the filter element]. At the same time, the dust exhaust valve needs to be cleaned from time to time every week.

2.Every 20,000 kilometers of driving, the main filter element and the safety filter element need to be replaced at the same time [this product is a desert filter air filter, please distinguish it from the oil bath air filter for maintenance requirements].
Second, the operation of the vehicle will lead to the slow attenuation of the torque of the wheel bolts, and it may loosen or even break if it is not disposed of for a long time. For guaranteesThe whole vehicle is operating normallyWheel bolts need to be serviced regularly
1.Bolts need to be re-tightened every week or every 2,000 km by means of a tightening equipment of suitable torque [M22 bolt torque: (670 30) Nm, M24 bolt torque: (790 30) Nm].
2.After disassembling and assembling the wheels, it is necessary to tighten the wheel bolts to the specified torque in diagonal order, and after running for 50-100 kilometers, tighten the wheel nuts again according to the specified torque. [Please use a tightening device with appropriate torque, if the tightening equipment torque is too large, the wheel bolts may be damaged and cause breakage].
