REVIEW
Warning Actions
Stop safely and correct the cause before returning the crane to service.
RED
Engine oil pressure
Action: stop the engine immediately. Check the oil level, filter, cooler and turbo oil lines; do not restart until correct pressure is verified.
RED
LMI/LML overload
Action: stop lifting, do not override the system, and lower the load by controlled descent. Verify the load chart and crane configuration.
RED
Anti-two-block
Action: stop hoisting immediately, lower the hook block safely, and inspect the switch, rope and boom-tip sheaves.
RED
Wire-rope damage
Action: stop all operations for broken wires, kinks, birdcaging, corrosion or diameter loss; remove a rejected rope from service.
AMBER
Hydraulic oil temperature
Action: stop lifting, stabilise the load, idle without hydraulic movement, and check oil level, filters and cooler cleanliness.
AMBER
High wind speed
Action: reduce radius, lower the load, and stop lifting when wind reaches the limit for the fitted crane configuration.
AMBER
Slewing anomaly
Action: stop slewing and inspect reducer oil, ring bolts, gear teeth, lubrication and bearing condition.
AMBER
Low fuel
Action: refuel before continuing. Do not run the Cummins QSM11 dry, because air entry can require professional fuel-system bleeding.
AMBER
Hydraulic filter indicator
Action: lower the load first, then replace the clogged return or pilot filter at the next safe opportunity before heavy lifting continues.
AMBER
Ground or track issue
Action: stop lifting, re-level the crane, improve mat support, or repair loose or damaged undercarriage components.
Critical rule: overload, anti-two-block, wire-rope failure, oil-pressure loss or uncontrolled movement requires full stop. Do not continue work by bypassing safety devices.
