What are the Pre-Operation Checks for the Explosion-Proof ZWY80 Wheel Mucking Loader?

Before using the explosion-proof ZWY80 wheel mucking loader, it’s essential to conduct thorough checks to ensure safe and efficient operation.

1) Cable Selection and Connection: Choose a suitable cable of 40-80 meters in length. Connect one end to the loader’s control box (or explosion-proof magnetic starter) at the designated location. The other end should be connected to a three-phase AC power supply with leakage protection and a grounding resistance of less than 2Ω.

2) Electrical Inspection: Check if the residual current circuit breaker and voltage are normal. Inspect the cables for integrity and ensure there are no loose or detached connections. If any abnormalities are detected, work must be prohibited until repairs are made.

3) Control System: Ensure all control levers are in the neutral position. The operation should be smooth and free of any sticking phenomena before proceeding.

4) Hydraulic System Examination: Verify that all hydraulic system components and connecting pipelines are securely fastened without any significant leaks. The hydraulic pipelines should meet specifications (with oil levels exceeding 4/5 of the total tank capacity). Hydraulic oil must be kept clean and should only be replenished from clean containers, adding it from the hydraulic air filter if necessary. Promptly refill oil levels if they are insufficient.

5) Inspection of the Conveyor System: Ensure the conveyor belt is intact with no misalignment issues. The tension should be appropriate, and the idler rollers should rotate smoothly without any abnormal sounds.

By meticulously following these pre-operation checks, operators can ensure the safe and effective use of the explosion-proof ZWY80 wheel mucking loader in mining operations.
