Check level on dipstick before engine start — never check during running. Top up with CI-4 SAE 15W-40 WEICHAI-approved oil if below MIN.
Act if: below MIN — top up; milky/foaming oil — stop engine immediately. Inspect block, drain plug, and oil lines for leaks.
Check level through sight hole on expansion tank — top up with WEICHAI-approved premixed antifreeze if below MIN.
Act if: below MIN — top up. Before opening filler cap on hot engine: press air-bleeding button to release pressure first.
Check fuel level (400L tank) — refuel if below 25% (100L). Use 0# diesel (GB252) summer; grade per ambient temp in winter.
Act if: below ¼ tank — refuel before the shift. Inspect fuel cap seal. Drain fuel filter water separator bowl if water is present.
Check hydraulic tank level (310L SANY-approved fluid) — top up if below MIN. Inspect all hoses, connections, and fittings for leaks, chafing, or damage.
Act if: below MIN — top up; milky/white colour (water contamination) — stop and investigate. Do NOT adjust relief valves. System max pressure 35 MPa.
Check air cleaner restriction indicator (per WP10 Manual §5.1). Dry-type air cleaner — do NOT oil the filter elements.
Act if: indicator shows restriction — remove and inspect main filter element; clean before restarting.
Inspect main hoist rope (Φ26mm×340m), aux hoist rope (Φ26mm×260m), boom hoist rope (Φ22mm×205m) for broken wire strands, kinks, bird-caging, deformation, corrosion.
Act if: ISO 4309 rejection criteria met — remove rope from service immediately. Do not defer.
Check all lattice boom connecting pins, locking pins, and retaining clips — must be fully engaged and pinned. Inspect jib attachment pins if FJ or LJ configuration is assembled.
Act if: any loose or missing pin — do NOT operate.
Inspect both crawler tracks for wear, cracks, broken or missing pads (950mm, 66 pcs×2). Check track tension per SANY specification — adjust both sides independently if required.
Act if: loose/over-tight, cracked or missing pads — do not travel until corrected.
Verify rear counterweight (55t: 13t tray + 6t×6 middle + 3t×2 upper) and carbody counterweight (10t×2) are correctly stacked, fully pinned, and locked.
Act if: missing or improperly stacked weight — do NOT lift.
Inspect main hook (150t, 7 sheaves) and active aux hook for cracks, deformation, twist beyond 10°, or failed latch.
Act if: cracked or deformed hook — replace immediately. Weld repair of hooks is prohibited.
Power on SYIC-III: verify all displays, LMI tri-colour indicator, anemometer, boom angle, load display, and all camera feeds operational.
Act if: limiter fault, no display response, or an alarm that will not clear — do not lift. Confirm LMI cutoff at 102% by function test per SANY O&M manual.
Test slewing lock, travel brakes, seat interlock, and function lock lever before first lift. Test all three slewing modes (anti-slip / semi-drift / drift) if changing modes for the day's work.
Act if: a brake will not hold — do not operate; rectify first.
Grease daily lubrication points: boom foot pins, all boom section connecting pins per assembled configuration, slewing ring gear teeth (SANY-approved grease), track rollers as required by condition.
Act if: no old grease purges out — keep applying until it exits. Every 8–10 operating hours at minimum.
Check cab glass for visibility (clean if obscured). Verify seat belt serviceable. Test emergency stop button — confirm all crane functions cut immediately. Test horn.
Act if: emergency stop does not cut all functions — do not operate. Confirm fire extinguisher is present, charged, and within inspection date.
Verify correct SANY SCS1500A load chart for the current configuration (H / FJ / LJ) and current counterweight combination is present, legible, and accessible in cab.
Act if: load chart missing or incorrect — operating without the correct load chart is prohibited. Do not rely solely on SYIC-III LMI display — paper load chart must be present as backup.
Check slewing ring drain/purge holes are clear and not blocked by old grease. Fresh grease visible at purge holes confirms lubrication is reaching the three-row roller bearing race.
Act if: blocked drain — grease not circulating — premature bearing wear. Clear drain before operating.
Walk around machine before engine start: confirm no personnel under the boom, in the slewing path, or adjacent to crawler tracks. No tools, rigging, or obstructions on machine body or in the working area.
Act if: any personnel or obstruction — do not start until area is clear. Sound horn before starting engine and before first slew or travel move.

Monitor SYIC-III LMI display for alerts. RED = stop crane operation immediately. AMBER = corrective action required before next lift. Do NOT bypass any alarm device.
Load reached 102% of rated — SYIC-III automatically cuts all crane functions.
Immediate action: stop all crane actions — do NOT try to override. Reduce load to clear cutoff.
Risk if ignored: LMI auto-cutoff leaves crane unresponsive until load is reduced below limit.
Boom angle reached max set limit — first stage alarm then hard auto-cutoff.
Immediate action: stop luffing immediately — lower boom to operating range (30°–84°).
Risk if ignored: boom structural backlash or structural failure at over-angle.
Hook triggered limit switch at boom head — buzzer alarm + hoisting cutoff.
Immediate action: stop hoist-up immediately — lower hook to clear limit switch position.
Risk if ignored: rope over-wrap on drum or boom head structural impact.
WP10 coolant temperature above safe operating limit — dashboard alarm.
Immediate action: stop engine immediately — check coolant level, water pump belt, and radiator.
Risk if ignored: engine head warp, seizure, or fire if continued under high temp.
WP10 oil pressure below minimum threshold — dashboard alarm.
Immediate action: STOP ENGINE IMMEDIATELY — check oil level, oil filter condition, oil pump.
Risk if ignored: catastrophic engine bearing, con-rod, and crankshaft damage.
One or both crawler tracks off or detected tension loss.
Immediate action: stop all travel and slewing — inspect both track systems before moving.
Risk if ignored: complete loss of machine mobility and crane structural instability.
Rope approaching last 3 wraps — proximity switch triggered on drum.
Immediate action: stop lowering immediately — re-hoist to restore safe drum rope reserve.
Risk if ignored: rope end pulls off drum — sudden uncontrolled load drop.
Slewing cannot be arrested or held — wet spring-loaded slewing brake not holding. Superstructure may drift under suspended load.
Immediate action: STOP all crane operations — do NOT initiate any slewing. Lower and secure suspended load to ground. Ground crane and call SANY service. Do NOT attempt field repair.
Risk if ignored: uncontrolled load swing, structural overload of boom base, personnel injury from uncontrolled superstructure rotation.
Load equals 100% of rated capacity — LMI red indicator active.
Immediate action: stop adding load — assess rigging, consider reducing operating radius.
Risk if ignored: 100% IS the rated limit — no further load margin remains before 102% auto-cutoff.
Load 90–100% — intermittent alarm, yellow indicator active.
Immediate action: monitor continuously — reduce hoist/slew speed, prepare to stop.
Risk if ignored: approaching rated limit — slew and travel functions restricted by SYIC-III.
Anemometer on boom top exceeds safe operating wind speed.
Immediate action: lower boom to travel position — cease all crane operations.
Risk if ignored: wind load causes uncontrolled load swing and structural overload.
Tank below ~10% (40L of 400L tank).
Immediate action: complete current lift safely — refuel immediately before next lift.
Risk if ignored: engine cut-out during lift = uncontrolled load drop.
24V system voltage drop — weak battery or alternator fault.
Immediate action: check both 12V×180Ah batteries and alternator charging output.
Risk if ignored: unreliable SYIC-III operation — risk of mid-lift control system failure.
Return oil temperature exceeding safe limit — SYIC-III hydraulic temp alarm active.
Immediate action: complete current lift safely, then idle with no load to cool. Check hydraulic tank level and oil cooler fins for blockage.
Risk if ignored: hydraulic seal degradation, oil viscosity breakdown, pump cavitation, and cylinder rod seal damage.
