During the operation of the excavator, if the gearbox trips, the machine should be stopped (or continued to drive) in a timely manner, and the cause should be identified and the fault eliminated. The specific method is:
(1) When there is a "gear shift" when driving on flat roads, you can stop the machine according to the normal shutdown instructions, carefully investigate the cause, and troubleshoot the problem.
(2) When there is a "gear jump" when driving uphill, you can set the gear to the low speed position or the first gear position, and stop the machine when it reaches the top of the slope to troubleshoot; If the downshifting is unsuccessful or if there is another "gear jump", the machine should be stopped according to the action instructions and requirements of the ramp shutdown, and then the fault should be eliminated.
(3) When there is a "gear jump" when driving on a downhill slope, the gear should be shifted to a high speed position according to the instructions for upshifting or "emergency downshifting" measures should be taken. After the machine reaches the bottom of the slope, it should be stopped for inspection and troubleshooting; If "upshifting" or "downshifting" is unsuccessful, or if "skipping" occurs again (in neutral gear), the driver can control the engine speed at medium speed (to prevent the engine from stalling), use the "braking" method to slide the machine to the bottom of the slope, and then troubleshoot. If "upshifting" or "grabbing gear" is unsuccessful, or if "skipping gear" occurs again (in neutral gear), and the machine is in a downhill slope (at this time, the machine will quickly "dive" towards the bottom of the slope), it should be quickly stopped according to the action essentials and requirements of the downhill shutdown, and then the fault should be deducted.
