FIELD: transport.SUBSTANCE: working mechanism comprises basic mechanism, cab and cab manipulator articulated with basic mechanism designed to change the cab position relative to said basic mechanism. Note here that cab manipulator is equipped with at least one hydraulic actuator to turn the cab about horizontal axis relative to basic mechanism. Note here that said cab id coupled with said manipulator to allow the turns actuated by tilt control hydraulic drive. Besides, said working mechanism includes the cab emergent exit system incorporating one emergent tilt valve for cab tilt adjustment device designed to orient the cab in normal position in emergent exit.EFFECT: reliable escape of engineman cab.9 cl, 3 dwg |
