| Hydraulic System Problem |
The grab bucket's movements were slow and weak. |
Hydraulic oil contamination, decreased pump efficiency, and excessively high oil temperature |
Regularly replace filter elements, use high-quality hydraulic oil, and add a cooling system. |
| |
hydraulic leakage |
Aging seals and loose joints |
Use high-performance sealing materials and regularly inspect fasteners. |
| Wears Structure |
|
Long-term impact load, material fatigue |
Wear-resistant steel plates are used, reinforcing ribs are added, and regular flaw detection is performed. |
| |
Wear at hinge points |
Poor lubrication, dust intrusion |
Design a sealed lubrication structure and use self-lubricating bearings. |
| Electrical and control problems |
Inaccurate control and delayed response |
Sensor failure, controller aging |
Upgraded to a digital controller and added auxiliary sensors. |
| Crawling efficiency issues |
Incomplete or leaky material collection |
Bucket teeth wear and poor closure |
Optimize the shape and material of the bucket teeth, and adjust the stroke and pressure of the hydraulic cylinder. |
| Installation and maintenance issues |
Issues include difficult maintenance and long downtime. |
Complex structure and inconvenient to assemble and disassemble |
Modular design includes a maintenance manual and training. |
