Fault Phenomenon: Dingli GTBZ26 telescopic boom aerial work platform on level ground, the instrument continuously alarms “Chassis Tilt,” restricting boom movement.

Troubleshooting Process:
– Checked ground: ground is indeed level.
– Checked tilt sensor: sensor mounting bolt loose.
– Checked wiring: no open circuit.
– Checked calibration: recalibration failed.

Root Cause: The tilt sensor has internal zero-point drift or the mounting bracket is deformed.

Required Parts: Tilt sensor assembly.
