Many veteran drivers may think that the cab turnover rate is very low, but does the cab turnover operation really comply with the regulations? If it is not standardized, how to carry out standardized operations? This time, I will tell you in detail about the standardized cab flipping process through the following introduction!
Pre vehicle preparation
When repairing a vehicle, it is usually necessary to raise the driver's cab. Before lifting the cab, the following preparations should be made: sufficient turning space is required at the front and above of the cab. Tighten the parking brake and, if necessary, block the wheels as an auxiliary means to prevent vehicle movement. Place the gear lever in neutral. Open the front flip. Turn off the auxiliary heating system. Remove all loose components inside the cab, close all cab doors, drawers, and storage boxes.
After confirming the above preparations, the cab can be flipped over.
Preparation for Electrical Flipping Operation
1. Turn off the engine, then turn the ignition switch to "ACC" or "on", and then turn on the flip power switch.
2. Turn on the flip power switch.
Electric lifting
1. Then turn the flip handle to the cab raised position.
2. Press the electric lifting button to raise the cab to the maximum angle. After confirming the center of gravity of the cab, release the lifting button before operating under the vehicle.
Electrical drop
To tilt the cab backwards, first turn the rotary handle to the downward position, then press the electric lifting button to lower the cab until the hydraulic lock of the cab is engaged, and then release the lifting switch.
2. Return to the cab, turn on the key switch, confirm that the flip indicator light is off, and finally close the front cover.
Manual flip operation
Manual lifting:
When using the manual cab flipping mechanism, turn the flipping handle to the cab lifting position, remove the lifting tool from the onboard toolbox, shake the tool, and lift the cab to the maximum angle. After confirming that the cab has flipped the center of gravity, remove the lifting tool.
Manual reverse:
2. To lower the cab tilting mechanism, first turn the rotary handle to the lower position and shake the rocker arm of the manual pump to lower the cab until you hear the hydraulic lock of the cab engage. Return to the cab, turn on the key switch, confirm that the flip indicator light is off, and finally close the front cover.
matters needing attention
If no resistance is felt when lifting the cab, check if there is enough oil in the oil pump.
2. If there is significant resistance when lifting the cab, check if the oil pump reversing handle is in the correct position.
Through the introduction, it can be seen that the process of flipping the cab is neither difficult nor difficult. The key is to see whether the flipping mechanism is installed properly. If the installation position is not accurate enough, it will not only affect the flipping process of the cab, but also cause wear and tear on the flipping mechanism components inside the cab due to the non-standard flipping action.
