Carter excavators unilateral couldn't walk?

Carter excavators machine can't move, Just one can't move) The reasons for the failure phenomena are commonly 4 points: 1 carter excavators damage of final drive. If you want to know whether this reason, this time can check excavator carter in the final drive out whether there is debris in the oil? There are, for this reason. 2 walking carter excavators, motor brake loose. If in the first point of oil without sundry, would have resulted in a 'carter excavators machine can't move ( Just one can't move) 'the cause of the failure is the walking motor brake loose carter excavators. 3 to avoid motor valve damage. At this point you can check after carter excavators walking motor valve exchange, unloading hydraulic excavator carter walking motor normal? At this time is normal, for motor valve damage. 4 if at this point, the unloading hydraulic excavator carter walking motor are not normal, they lead to 'carter excavators machine can't move ( Just one can't move) 'the cause of the fault is in place for carter excavators' walking motor damage. The above is' carter excavators machine can't move, Just one can't move) 'common cause failure, repair method is to overhaul their defective parts or replace new one. When other working device and walking speed is normal, carter excavators can't turn the cause of the failure occurs are: 1 carter excavators swing mechanism is damaged, check the release of oil from the carter excavators slewing mechanism of any impurities, can know whether the fault reason. Impurities is damage of slewing mechanism. 2 damage of carter excavators, motor brake. Check excavator carter control valve is the movement of the slide valve can know whether for this reason, slide moving smooth, the brake motor damage. 3 on the second point, if the slide valve movement is not smooth, is' when other working device and walking speed is normal, carter excavators can't rotary 'the cause of the problem is, the control valve valve failure, at this time to replace or repair. 4 carter excavators rotary motor damage. 5 carter excavators slewing brake solenoid valve failure. 6 the relief valve damage. 7 PPC valve damage. All 7 above could lead to 'when other working device and walking speed is normal, carter excavators can't rotary' failure, which specifically for the cause of the problem leads to master excavator field inspection is needed.
