FIELD: transport.SUBSTANCE: invention relates to automatic control over lift of motor-drive vehicle chassis element above the surface. Proposed system comprises level control mechanism, lift transducer, and pressure transducer, and control unit. Control unit allows defining the compliance of the first criterion of fluid pressure increase per lift unit. If said first criterion is observed, control unit allows defining compliance of second criterion with controlled parameter. If said second criterion is observed, control unit generates control signal to stop chassis lift. Motor transport facility comprises above described system. Proposed method consists in recording lift height and fluid pressure in level control mechanism chamber. In lifting chassis elements, compliance of said two criteria with controlled parameters is controlled. If second criterion is observed, chassis element lift is terminated.EFFECT: higher safety.15 cl, 6 dwg |
