How Can Steering Failure Be Prevented in an Electric Rock Loader Used Underground?
An electric rock loader is widely used in underground mines and industrial plants, but harsh underground conditions and long working hours often lead to frequent failures and severe equipment aging. Among these issues, steering failure is especially dangerous in high-risk mining operations, so effective prevention measures are essential.
Common Causes of Steering Failure
In many cases, steering failure occurs when the control valve cannot rotate or only moves with great force. The steering system of an electric rock loader is controlled by hydraulic valves, so most faults are related to the hydraulic system.
First, check whether the internal mechanical parts of the hydraulic steering unit are jammed. Disassemble the valve to see if any components have fallen off and become stuck inside.
Next, inspect the oil inlet of the steering valve block. Small particles or debris may block the check valve near the inlet, preventing normal oil flow. Once these impurities are removed, the steering system usually returns to normal operation.
Hidden Risks in the Hydraulic System
In one real case, the customer traced the source of debris and found that a wire-gap oil filter in the hydraulic return line used an adhesive that easily peeled off. These particles entered the oil tank through the return line, were pumped into the steering unit, and finally blocked the check valve, causing steering failure.
Effective Prevention Measures
To reduce the risk of steering failure, it is recommended to use original factory hydraulic components for the electric rock loader. Avoid parts made of materials that may peel, break, or dissolve after long-term immersion in hydraulic oil. High-quality materials and clean hydraulic systems are key to reliable steering performance.
Conclusion
By improving hydraulic system cleanliness and using reliable original components, steering failures can be effectively avoided. Proper maintenance and material selection help ensure safe and stable operation of the electric rock loader, reducing downtime and risks in underground mining environments.
