Detailed technical specifications for SANY SR285R C10 Rotary Drilling Rig
Daily pre-start checks, hourmeter-based service schedule, and warning-alert actions for the SANY SR285R hydraulic rotary drilling rig. This section is based on the SR285R maintenance reference: ISUZU 6WG1X engine, 300 kW @ 1,800 rpm, 285 kN·m rotary torque, 2,300 mm max pile diameter, 94 / 61 m max pile depth, Ø36 mm main winch rope, Ø20 mm auxiliary winch rope, and 100 t operating weight. Verify all intervals, fluid grades, fluid volumes, torque values and alarm set-points with the official SANY SR285R O&M manual before service.
Complete before every shift, approx. 15–20 minutes. Do not operate if any check fails or cannot be confirmed.
Check dipstick with engine cold on level ground. Top up if below MIN. Typical reference grade: API CI-4 or better, SAE 15W-40.
Act if: Below MIN mark or oil is milky / black-discoloured — do not start engine.
Check expansion tank level. Top up with correct coolant mix.
Act if: Level below MIN, coolant is brown/rusty, or any external leak is visible.
Check fuel gauge, fill with clean diesel, and drain water from the fuel pre-filter bowl.
Act if: Fuel below 25% capacity or water / contamination is found in the bowl.
Check sight glass on hydraulic tank. Top up if below lower mark.
Act if: Below lower mark, milky oil, or any leak at hose connections.
Check restriction indicator lamp on the instrument panel.
Act if: Restriction lamp is illuminated — do not start; replace filter first.
Check terminal tightness and corrosion. Check electrolyte level if accessible.
Act if: Loose terminals, severe corrosion, or electrolyte below MIN mark.
Check grease reservoir level and confirm auto-lube pump cycles on startup.
Act if: Reservoir empty or pump fails to cycle — manually grease all points.
Visually inspect hoses, cables, structural connections, fasteners, and ground under the machine.
Act if: Fluid leak, damaged hose, cracked weld, or loose fastener is found.
Inspect Ø36 mm rope full length for kinks, bird-caging, broken wires and corrosion.
Act if: 3 or more broken wires in one lay — remove rope from service immediately.
Inspect Ø20 mm auxiliary rope with the same criteria as main winch.
Act if: Any similar defect — report to site supervisor before starting shift.
Check guide sliding strips for wear and confirm locking pin engages fully.
Act if: Locking pin fails to engage or guide strip is cracked / missing.
Test SANY-ADMS panel, depth meter, overload alarm, E-stop and all cameras.
Act if: Any safety system is non-functional — do not operate until repaired.
Use hourmeter reading for service timing. Lower-interval items must be done at every higher-interval service.
