Pneumatic Rock Loader Trial Run Instructions

The pneumatic steel wheel rock loader is an efficient machine designed for mining operations. To ensure safe and reliable performance, operators must follow the proper inspection, trial run, and operating procedures.

Pre-Operation Inspection

Before use, conduct a thorough inspection of the machine. All bolts at connection points must be tightened, and the four steel wire ropes should maintain equal tension. Check whether each control valve is flexible, and ensure that all pipelines are free of air leakage.

Trial Run

The machine should undergo an unloaded trial run before official operation. Move the control handles to perform forward, backward, left turn, right turn, bucket lifting, and bucket lowering, each 5 to 8 times. Only when the loader operates smoothly without jamming can it be put into service.

Operating Procedures

During operation, the loader should move toward the ore pile while lowering the bucket. When the bucket penetrates the ore pile, the travel motor continues driving forward so that the bucket inserts with force and vibration. After the bucket is filled, raise the bucket to unload while moving the loader backward.

Operators must follow these rules:

1. Start the machine smoothly to avoid sudden force. Stop compressed air supply once the bucket passes the vertical position, allowing the frame to unload rocks smoothly.

2. The operator must stand on the pedal to prevent accidents.

3. Shovel from the middle of the working face first, then the sides. Small rocks can be loaded quickly; larger rocks may require multiple vibrations.

4. Always lower the bucket and lock the handle before leaving the machine.

5. Maintain at least 300 mm between the loader’s outer side and the roadway wall to protect the operator.

6. During blasting, park the loader at least 30 meters away.

By following these guidelines, the pneumatic steel wheel rock loader can operate safely, extend service life, and maximize efficiency in mining applications.
