APPARATUS AND METHOD FOR CONTROLLING SWING OF CONSTRUCTION MACHINE
Disclosed are an apparatus and method for controlling the swing of a construction machine, which are capable of achieving a preferential boom-up function or a preferential swing function based on a swing angle during the loading work using a complex operation of a boom-up and swing. The method for controlling the swing of a construction machine, comprises: a first step of selecting a preferential boom-up function or a preferential swing function via an external input device; a second step of determining whether to operate a complex operation by an operation signal based on the operation of a boom joystick and a swing joystick; and a third step of variably controlling, if the preferential boom-up function is selected and if it is a complex operation condition, the degree of opening of an electro hydraulic valve for the swing so as to relatively limit the flow that is supplied from a hydraulic pump to a swing motor, and variably controlling, if the preferential swing function is selected and if it is a complex operation condition, the degree of opening of an electro hydraulic valve for the boom so as to relatively limit the flow that is supplied from the hydraulic pump to a boom cylinder.
