The embodiment of the invention is suitable for the technical field of hoists, and provides a braking torque control method, device and system of a hoisting system. The lifting system comprises a traction rope, a guide wheel, a disc brake for driving the traction rope to move on the guide wheel, and a first lifting container and a second lifting container which are positioned at two ends of the traction rope; the method comprises the following steps: determining a first braking torque when a traction rope moves according to the radius of a guide wheel, the first weight of a first hoisting container and the second weight of a second hoisting container; obtaining the angular acceleration of the guide wheel when the traction rope moves at the target constant speed; according to the angular acceleration, the first braking torque and preset equivalent resistance torque and preset equivalent rotational inertia of the lifting system, second braking torque to be output by the disc brake when the traction rope moves at the target constant speed is determined; and controlling the disc brake to output the second braking torque. By adopting the method, the lifting container can be stably controlled to move at the target speed.
