Abstract (en)
The present invention relates to a method and a system for controlling the speed of a winch, whereby safety and operability are improved without being put into a free fall state and, at the same time, a lowering speed equal to that of the free fall state can be obtained. To this end, a rotation speed of a winch drum (13) is substantially a direct and exclusive speed with respect to the stroke of an operating lever (5) until a predetermined stroke of the operating lever (5), while the speed is a different speed with respect to the same stroke of the operating lever (5) in response to a speed mode selected from a plurality of speed modes at strokes over the predetermined stroke. <IMAGE>
