The hydraulic wood grapple is reciprocating rapidly, and the oil return speed is faster and the cutting pulse is larger, which will make the hydraulic oil aging faster, and the wood grapple system will also suffer damage. When you use the wood grapple, you should How to protect it?

Using high-quality hydraulic wood grabber, inferior products are likely to have deficiencies in all aspects, so the failure rate will be higher, and it is very easy to damage the excavator itself.

Choose a suitable engine speed, the hydraulic wood grab has low working pressure and flow requirements, and the medium level throttle can operate. If the throttle is too high, not only will it not be increased, but on the contrary, there will be a greater impact, so the hydraulic oil will also be abnormally raised in temperature, which will damage the hydraulic system.

The buttering posture should be correct, and the frequency and quantity should be as accurate as possible. The lubricating oil must be filled in the state of steel brazing and straightening. Fill it every 2 hours. Fill the lubricating oil when the drill rod is suspended, the grease will enter the striking chamber, and then abnormal phenomena will occur, which will directly damage the hydraulic pump.

The amount of hydraulic oil is still polluted: determine the pollution of the hydraulic oil of the hydraulic grapple as soon as possible. When the hydraulic oil drops, cavitation will occur, and the hydraulic pump will malfunction, causing damage to the piston and cylinder. Therefore, the oil level should be checked every day before use.

Ensure the cleanliness of the wood grabber. When installing the wood grabber, it is necessary to fully clean the pipeline, and make a cyclic connection to the oil return path. When replacing the bucket, the wood grabber pipeline needs to be blocked to maintain the cleanliness of the pipeline.

Replace the oil seal in time. The oil seal is a consumable part. Therefore, the hydraulic wood grabber needs to replace a return oil seal every 600h to 800h. When the oil seal leaks, stop the operation immediately and replace it, otherwise Dust can easily enter the hydraulic system and damage related parts.
