Fault Phenomenon: During boom extension on the XCMG XCA1600, multiple sections extend at inconsistent speeds, exhibiting sticking and vibration.

Troubleshooting Process:
– Check hydraulic system pressure: Main pump pressure is normal.
– Check extension cylinders: No signs of internal leakage.
– Check slider and boom clearance: Found severe wear on the 2nd section sliders, excessive clearance causing eccentric load.
– Check wire rope tension: Uneven tension.
– Replace worn sliders and re-adjust wire rope tension.

Fault Source: Boom slider wear causing increased friction and eccentric loading.

Required Parts: Nylon sliders, wire rope.
