Abstract: A system for enabling an upper swing body of construction equipment to swing freely. A working device is attached to the upper swing body to lift and move an object. A swing motor is connected to a power unit to swing the upper swing body. A controller is electrically connected to the working device and the swing motor to detect forces applied to the working device, and based on the detected forces, generating a control signal to control the swing motor so that the upper swing body swings freely. The system enables the upper swing body to swing freely to reduce energy consumption while ensuring safety when the upper swing body lifts a load.

Abstract: An agricultural implement having a center section and wings is converted from dedicated free-floating wings to provide active-down pressure upon the wings. The agricultural implement has been manufactured with hydraulic cylinders to raise and lower the wings. The hydraulic cylinders are connected at one end to the center section, and at the other end to the wings by way of pins and slots. The hydraulic cylinders, the pins, and the slots are configured so that when the wings are lowered, the wings of the agricultural implement as manufactured free-float vertically by way of unrestricted motion of the pins in the slots. Tie-plates and second pins are configured to engage the first pins and the slots, and to restrict the motion of the first pins in the slots. A pressure controlled hydraulic circuit is connected to the hydraulic cylinders and controls an amount of down-pressure applied by the hydraulic cylinders.
