What is a Hilift Drum？

Hilift Drum refers to a wire sheave that contains both a flat sheave part and a tower sheave part. At a certain width, the radius does not change, and at other widths the radius is gradually increased. Similarly, if the load is constant, the moment on the axis of the reel does not change in the flat wheel part, but gradually increases in the tower wheel part. This kind of reel is generally used for high lift.
