The invention discloses a power control method for hoisting equipment. The method comprises the steps of: 1) detecting the current loading pressure of the hoisting equipment's power system, converting the current loading pressure into an electrical signal, and directly conveying the signal to ECU of an engine through a circuit; and 2) according to the electrical signal, outputting an engine speed matching with the current loading pressure. According to the method, the current loading pressure is transferred the engine ECU in the form of the electric signal, the mode and time for transferring an external load signal to the engine are changed, the time required for signal transmission is reduced, and the engine can rapidly response in advance. Thus, flameout caused by too much sudden fall of the engine speed can be avoided when the pressure load suddenly increases, thus effectively improving the power adaptability of engine under a low speed condition. The invention also discloses a power control system for hoisting equipment.
