Detailed technical specifications for XCMG XGC80-I 80T Crawler Crane
Daily pre-start checks, hourmeter-based service schedule and warning-alert actions for the XCMG XGC80-I 80-tonne crawler crane. Machine specifications are taken from the OEM brochure; maintenance data is based on the supplied XGC80-I maintenance reference and should be verified with the official XCMG XGC80-I service manual before maintenance.
Complete before every shift. These checks take about 15–20 minutes and help prevent damage, downtime and safety incidents.
Pull dipstick with engine off on level ground. Oil should be between MIN and MAX.
Act if: oil below MIN, milky, or contains metal particles.
Check expansion tank with engine cool; level should be between MIN and MAX.
Act if: low level, discoloured/oily coolant, or hose/radiator leak.
Check fuel gauge. Drain separator bowl until clean fuel flows and inspect lines.
Act if: fuel below 1/4, excessive water, or fuel-line leaks/damage.
Check sight glass on hydraulic tank with cylinders retracted; level should be in green zone.
Act if: level below minimum, oil foamy/cloudy/dark, or visible leaks.
Inspect visible rope length for broken wires, kinks, bird-caging, corrosion and flattening.
Act if: >3 broken wires in one lay, any kink/crushing, or diameter reduction >5%.
Inspect hook body for cracks, bending and throat opening; test latch spring action.
Act if: throat opening increased, latch broken/missing, or hook cracks visible.
Walk around and inspect chords, lacing, welds, connection pins and cotter pins.
Act if: bent chord, cracked weld, missing/bent cotter pin, or loose connection pin.
Check track tension, shoes, bolts, sprockets and rollers.
Act if: sag >50 mm, loose/missing shoe bolts, or cracked sprocket teeth.
Inspect bolt torque markers and listen for unusual noise during slow slew.
Act if: torque markers misaligned or grinding/clicking during slewing.
Power on Hirschmann LMI, verify display data and run self-test if available.
Act if: self-test fails, error codes show, or boom angle/load readings are incorrect.
Test emergency stop, boom angle limiter, anti-two-block, anemometer and tricolor light.
Act if: any device fails or emergency stop does not halt all movements.
Check warning lights, work lights, travel alarm, horn, backup alarm and warning beacon.
Act if: warning lights stay on or horn/backup alarm/work lights fail.
Test all control levers; check seat belt, mirrors, wipers and A/C.
Act if: lever is stiff/unresponsive, seat belt damaged, or mirrors broken/missing.
Grease daily lube points per OEM chart: boom foot pin, hoist drum bearings and sheave pins.
Act if: grease point blocked/damaged, no grease emerging, or dry squeaking at pins.
Inspect ground for soft spots, slopes, obstructions and underground utilities.
Act if: ground sinks under tracks, slope exceeds 1%, or utilities are not verified.
Use hourmeter reading for service timing. Do not delay service if due. Higher intervals include lower-interval checks.

RED = stop immediately. AMBER = take action before continuing work. Log every alert.
Actual load exceeds 100% rated capacity; red/yellow tricolor lights activated.
Immediate action: stop all movements, lower load to ground, do not slew or luff, verify load weight.
Risk if ignored: structural failure, boom collapse, tip-over and fatal injury.
Coolant temperature exceeds safe limit.
Immediate action: stop engine, allow 15-minute cool-down, check coolant, fan belt and radiator.
Risk if ignored: engine seizure, turbo failure and fire risk.
Sudden pressure loss; controls jerky or unresponsive.
Immediate action: stop movements, lower load if safe, shut down and inspect for burst hose.
Risk if ignored: uncontrolled load drop or boom collapse.
Over-wind protection triggered; rope at drum limit on boom head.
Immediate action: stop hoisting, lower hook, inspect rope for broken wires or kinks.
Risk if ignored: rope failure and uncontrolled load drop.
