Standardized operation can prevent damage to bucket cylinder of excavator

If the piston rod of the bucket cylinder reaches the end of the stroke of the rod cavity when the excavator is working, the internal limit ring is easily damaged under the pressure and impact. This will reduce the service life of the bucket cylinder. Therefore, when operating the machine, the bucket digging oil cylinder should retain 10~20 cm expansion allowance. This operation can prevent the fatigue damage of the steel ring and limit ring on the piston caused by the impact of long time and large load.
The excavation depth and excavation range are constantly changing during the operation of the excavator. Therefore, the bucket cylinder and connecting rod, the stick cylinder and the stick should be at a 90 ° angle when working. Do not continue to reach the end of the stroke. In this way, the excavator can obtain maximum digging force and maximum working efficiency.
