Abstract
A boom system includes a boom turret, a brake for preventing rotational movement of the boom turret, and a controller for actuating the brake. The brake prevents movement of the turret when the turret is subject to rotational loading below a torque threshold and allows rotational movement of the turret when the turret is subject to rotational loading above the torque threshold. The controller dynamically adjusts the torque threshold in response to changes in the position of the boom during operation of the boom system, including applying a lower torque threshold when the boom is in a first position and applying a higher torque threshold when the boom is in a second position.
