Strand Composition: "35W*K7" indicates 35 strands with 7 wires in each strand. "W" represents Warrington structure with wires arranged in combination of different thicknesses. "K" indicates compacted strand, generally cold-drawn with 10% compression rate.
Twisting Method: Typically uses opposite twisting directions for inner and outer strands. During production, inner layer is twisted first, followed by outer layer.
High Breaking Force: Compacted strand process and combination of wire thicknesses result in higher metal filling coefficient and greater breaking force compared to ordinary wire ropes.
Superior Wear Resistance: Small gaps between wires and smooth surface provide large contact area with pulleys/drums, offering higher wear resistance.
High Structural Stability: Compacted wires are arranged more closely, creating stable structure resistant to deformation under external forces.
Specification Dimensions
Common diameter specifications: 14mm, 16mm, 18mm, 20mm, 26mm, 32mm, 36mm, 46mm, etc.
Application Scenarios
Widely used in rotary drilling rigs, rubber-tyred gantry cranes, port machinery, truck cranes under 80 tons, crawler cranes and other lifting equipment.
Material and Strength
Manufactured using high-quality carbon steel or alloy steel. Typical strength grades: 1960MPa, 2160MPa.
