Guide pulley shall be set in front of diesel winch

The guide pulley shall be set in front of the diesel winch. The distance between the guide pulley and the axis of the drum shall be no less than 15 times of the width of the drum, that is, the inclination angle α shall not be greater than 2 degrees (Fig. 14-19). The non grooved drum shall be greater than 20 times of the width of the drum, so as to avoid excessive wear between the wire rope and the groove edge of the guide pulley; The direction of the wire rope winding into the drum shall be perpendicular to the axis of the drum, and the allowable deviation of verticality is 6 °. In this way, the wire rope loops can be arranged in order, so as to avoid oblique winding and mutual overlapping extrusion.
