Claim Text:
1. A boom system for supporting a load comprising: a boom configured to pivot upward and downward in a pivoting plane, said boom configured to su ort the load in either an aligned orientation or a non-aligned orientation, wherein the aligned orientation is defined as the load being directly below the boom in the pivoting plane, wherein the non-aligned orientation is defined as the load being outside the pivoting plane, such that the load imparts a torque on the boom; a boom turret configured to selectively rotate the boom safely while the torque imparted on the boom is below a torque safety threshold; a brake for preventing rotational movement of the boom turret, wherein when the torque imparted on the boom is turret is below the torque safety threshold, the brake prevents rotational movement of the boom turret, wherein when the torque imparted on the boom is above the torque safety threshold, the brake allows rotational movement of the boom turret; and a controller for automatically actuating the brake to dynamically adjust the torque safety threshold in response to changes in the position of the boom during operation of the boom system, wherein the controller applies a lower torque safety threshold when the boom is in a first position, wherein the controller applies a higher torque safety threshold when the boom is in a second position, wherein the brake is configured to allow rotational movement when the torque is above the torque safety threshold such that damage to the boom system is prevented.
