A hydraulic
system (170, 300, 400, 500) for controlling one or more hydraulic actuators (330, 330a, 330b) of movable members (110, 120, 130) on construction equipment (100), the hydraulic
system comprising a
control unit (150), a hydraulic tank (310), a
hydraulic pump (320) arranged to generate hydraulic flow to
hydraulic control valves (340, 340a, 340b) of the one or more hydraulic actuators (330, 330a, 330b), and an
unintended movement prevention
system (350, 410, 420, 510, 520, 540), where the
control unit (150) is arranged to generate an electric pressure enable
signal (360) in response to detecting an activated state of a remote-control device (200) associated with the construction equipment (100), where the
unintended movement prevention system (350) is arranged to divert at least part of the hydraulic flow from the
hydraulic pump (320) at a location upstream from the
hydraulic control valves (340, 340a, 340b) to the hydraulic tank (310) in response to loss of the electric pressure enable
signal (360).
