Swing brake control apparatus for construction machinery
The present disclosure relates to an apparatus for controlling a swing brake for construction machinery, comprising: a lower travel body; an upper swinging body supported at the lower travel body such that the upper swing body is capable of being swung; a swing motor for driving the upper swing body; a swing brake for braking the swing motor; a swing brake valve which operates to control the braking and releasing operations of the swing brake; a solenoid valve mounted on the swing brake valve to control the operation of the swing brake valve; an operation sensor which applies a first reference signal and a second reference signal in accordance with the motion of a swing operation control unit for controlling the operation of the upper swinging body, wherein said second reference signal is generated when an amount of displacement of the swing operation control unit is larger than the first reference signal; and a control unit, which operates the swing brake valve to release the swing brake when the first reference signal is inputted from the operation sensor, and which operates the swing motor when the second reference signal is inputted.
