The operation process of the mixer truck needs to be carried out in strict accordance with the specifications to ensure safety and efficiency. In this article, we will take LUYU self loading concrete truck as an example, and introduce you the detailed operation steps and precautions from several aspects, including before operation, during driving and after driving.

Before getting in the car

Note: Before the first work of the new car, be sure to grease the hydraulic system pin shaft and articulation.

Check whether the tire nuts, engine, and transmission each tightening bolt and pin shaft are loose; check whether each locking point is locked; check the tire appearance and air pressure (low pressure tire 4 air pressure, high pressure tire 8-10 air pressure).

Check whether the vehicle has oil leakage, water leakage and air leakage.

Check the engine oil (the amount of oil must be between the highest and lowest scales of the oil gauge), cooling water (Note: Do not open the water tank during or after the engine work to avoid danger).

Check the amount of oil in the hydraulic tank before and after (Note: 0 on the hydraulic oil radiator switch, indicating automatic; when the hydraulic oil temperature reaches 60 ° C, the radiator fan will automatically open the working state; 1 means manual, when the hydraulic oil radiator switch is in the manual state, the radiator fan is in a continuous working state); Normal use, the switch is in the 0 position.

Check torque converter fluid transmission oil (after engine ignition, the oil level is in the middle of the glass tube).

Check the amount of fuel in the diesel tank and the amount of water in the on-board water tank.

After getting in the car

Before the engine ignites, turn on the power master switch, and then check whether the left gear lever of the steering wheel is in the neutral position.

After the engine ignites, check the air pressure (must reach 0.4Mpa or more, otherwise the vehicle cannot walk), the torque converter pressure gauge (normal value 1.2Mpa), the number of engine revolutions, oil pressure, water temperature, battery voltage.

The vehicle starts

The right gear lever of the steering wheel is high and low speed conversion gear, which is divided into high speed gear, neutral gear, low speed gear. high speed gear when the mixer truck is walking (empty car driving), and low speed gear when working. It should be noted that when the high and low speed converse, it is necessary to ensure that the two gear levers on the left side of the steering wheel are in the "neutral" state. When the mixer truck is walking, step on the brakes, push the high-speed on the right side of the steering wheel, then push the low speed gear on the left side of the steering wheel, hang the forward gear to start, release the handbrake, foot brake, step on the accelerator, and then change the high-speed gear.
