What is the typical maintenance cycle for Pneumatic Anchor Cable Tensioning?

1. Daily Maintenance (per shift/day): Clean equipment of coal dust and oil stains, check for leaks in oil pipes and joints, and complete basic inspection and maintenance.

2. Weekly Maintenance (7 days): Tighten all connecting bolts, add grease, clean the oil pump filter element, and check for minor internal leaks.

3. Monthly Maintenance (30 days): Replace or filter hydraulic oil, inspect cylinder seals, and calibrate pressure gauge accuracy.

4. Quarterly Maintenance (90 days): Disassemble and clean the internal valve body, replace aged seals, and test the jack tensioning force.

5. Semi-annual Overhaul (180 days): Complete overhaul of the entire machine, replacement of worn parts, and on-site tensile force testing to verify performance.

6. Mandatory Replacement/Inspection Cycle: High-pressure hoses are mandatory replacement every 18 months; the jack body undergoes comprehensive flaw detection every 2 years; the entire machine is assessed for scrapping after 3 years of use.
