Fault Phenomenon: General diesel forklift during high-pressure lifting, the high-pressure hydraulic hose suddenly bursts, hydraulic oil sprays, mast drops rapidly.

Troubleshooting Process:
– Checked hose exterior: hose aged and cracked.
– Checked system pressure: pressure momentarily exceeded rated value.
– Checked hose fittings: fittings loose.
– Checked hydraulic shock: cushion valve failed.

Root Cause: Aging of the hydraulic hose reduces its pressure resistance, or excessive system pressure shock.

Required Parts: High-pressure hydraulic hose assembly.
