The invention discloses a counter weight control method and device for a hoisting machine. The method comprises the steps that after an initial control value is input through a handle to control two oil cylinders to go up and down synchronously, travel information of the two oil cylinders is detected; according to the travel information of the two oil cylinders, the datum oil cylinder and the adjusted oil cylinder are determined; the adjusted oil cylinder is controlled to slow down until a difference value between the travel information of the datum oil cylinder and the travel information of the adjusted oil cylinder is within a preset range, and a current real-time control value of the two oil cylinders is recorded; and the two oil cylinders are controlled to act on the basis of the travel information of the two oil cylinders and the recorded real-time control value of the two oil cylinders. By means of the counter weight control method and device, the technical problems that in the process that a hoisting machine controls a counter weight to go up and down stably in the prior art, lifting of the counter weight is adjusted with an oil cylinder at a certain side as the datum constantly, and consequently the effective control range of a handle is smaller, and counter weight lifting efficiency is low are solved.
