Test device for lifting equipment, and vehicle equipped with such a device

Abstract

------ Test device for lifting equipment, and vehicle equipped with such a device The invention relates to a test device (1) for lifting equipment (3), comprising a support frame (11), a hydraulic actuator (VR1), a hydraulic circuit (12), and control means (C), the hydraulic circuit (12) comprising a pressure accumulator (AC), a flow reducer (FR1), a three-way proportional valve (TS), a first 2-2 distributor (DK), a first inlet-outlet (VR1d), a second inlet-outlet (VR1e), a second 2-2 distributor (SV4), and a hydraulic fluid reservoir (RS);and the test device (1) being configured to perform a test, by adjusting the three-way proportional valve (TS) to a desired regulated pressure, and for an uphill test or a position-lock test, by moving the first 2-2 distributor (DK) to the second position, and for a downhill test, by additionally moving the second 2-2 distributor (SV4) to the second position. The invention also relates to a vehicle equipped with such a device. Figure to be published: Figure 3;
