Winch often has various problems in the course of work. In order to avoid such situations and tragedies, Ningbo Hipower Precision Technologies Co., Ltd. provides you with the best quality winch. This time, we bring you information about the selection of the wire rope for dispatching winches. :
Selection of wire rope
When the wire rope is wound in the right spiral on the winch drum, the right reins should be used; otherwise, the left reins are used. The wire rope of the same direction is soft, has a smooth surface, good fatigue resistance and long service life, and is mainly used in shaft and inclined well bucket lifting. The disadvantage is that loose knots cause knotting, so the inclined shaft train lifting is rarely used. Although the interaction 捻 wire rope is slightly worse than the same direction 捻 wire rope, but because it is not easy to loose, it is often used in mine lifting. The wire contact wire rope has been widely used due to its relatively large number of wires in the rope, compact structure, not easy to bend, fatigue resistance, high metal section coefficient utilization and long service life, but its manufacturing is complicated and the price is slightly higher. The point contact wire rope has a special structure due to its simple structure and its special structure and performance. The section of common steel wire rope for mining is arranged in a concentric circle to the right, 6 strands plus one core, and the number of filaments is 6×7 filaments (6 strands of 7 filaments), 6×19 filaments (6 strands of 19 filaments) and 6×37 (6 strands). 37 wire), etc., its tensile strength and the sum of the breaking force of the steel wire, etc., in line with the relevant national standards.
According to GB1102-74 and the Ministry of Metallurgy Standard YB829-79, the marking of the wire rope shall include: name structure, diameter, nominal tensile strength, toughness number, galvanized group, galvanized or glossy, slanting direction and standard number. For example, JD-2 dispatching winch uses 6 strands, 25 filaments/strand, diameter 15.5mm, nominal tensile strength 1700N/mm2, smooth surface I wire, right-hand twisted, filled wire rope, marked as: wire rope 6T—( 25)—15.5—170—I—light—right right (GB1102—74).
