The invention discloses a fault detection method for a dumper carriage incapable of descending after lifting. The fault detection method includes steps that a) detecting a lifting angle; b) detecting a distribution valve slide bar; c) detecting the kinematic pair of a lifting tilting mechanism; d) detecting a hydraulic cylinder piston rod; e) detecting a hydraulic cylinder body. Through performing the detection steps step by step, the fault part can be quickly judged, the overhauling efficiency is improved, the fit precision between components can be guaranteed, and the service life is improved.
