Fault Phenomenon: Asselift scissor lift platform when lifting, the two hydraulic cylinders move at different rates, causing the platform to tilt.

Troubleshooting Process:
– Checked hydraulic lines: lines not blocked.
– Checked flow divider valve: valve spool stuck.
– Checked cylinder internal leakage: one cylinder has internal leakage.
– Checked mechanical linkage: linkage broken.

Root Cause: The hydraulic flow divider valve is stuck, causing uneven flow distribution.

Required Parts: Flow divider valve assembly.
