The present disclosures relates to a safety device for preventing a working apparatus from being operated during regeneration of a diesel exhaust gas after-treatment device of a forklift-truck. The safety device for preventing a working apparatus from being operated during regeneration of a diesel exhaust gas after-treatment device of a forklift-truck according to the present disclosure includes: a hydraulic pump (30) configured to discharge high-pressure working fluid; a main control valve (50) provided with a plurality of working apparatus control valves, and configured to provide the working fluid to a desired working apparatus (80), among a plurality of working apparatuses (80); a remote control valve (60) controlled so as to provide pilot working fluid to the plurality of working apparatus control valves according to an operation of a working apparatus actuation lever (61); a pressure-reducing valve (70) controlled in such a way that high-pressure working fluid discharged from the hydraulic pump (30) is pressure-reduced to a pressure of the pilot working fluid to provide the pressure-reduced working fluid to the remote control valve (60); and a control valve unit (100) disposed upstream of the remote control valve (60), and controlled in such a way so as to block the pressure-reduced working fluid from being provided to the remote control valve (60) by receiving a signal from the controller (20) based on worker departure information when a worker leaves a driver's seat during regeneration of a diesel particulate filter (DPF, the diesel exhaust-gas after-treatment device). |
