Cable Leather Palm with Visual Wear Indicator
Problem: Palms wear thin due to repeated contact with the wire rope, and workers don't always know when to replace a pair of palms.
Solution: Full leather palms with a contrasting bottom layer that becomes visible when the top layer wears, providing a visual cue for immediate replacement and repair to avoid failure during lifting.
Replaceable Sacrificial Cover
Problem: Localized wear (center of palm, heel of thumb, pad of index finger) forces the entire pair to be discarded.
Solution: Bolt-on or stitched cover panels that can be replaced on-site in minutes, reducing waste and cost per service hour.
Kevlar-Reinforced Edge Binding and Stress Lines
Problem: Edge wear and seam tearing due to cable wear and repeated flexing.
Solution: Kevlar or aramid edge binding plus adhesive/high-strength thread at seam stress points (base of thumb, palm seam) prevents wear and tear.
Rope Grip Channel and Micro-Textured Palm Finish
Problem: Round ropes can slip and roll in flat palms, and oily conditions can reduce bite force.
Solution: A slightly contoured palm guides the rope, while micro-textured or tumbled leather (or thin nitrile dots) improves bite force on smooth surfaces.
Vibration-Damping Insert
Problem: Winch and tool vibrations during long lifts can cause numbness and fatigue.
Solution: Thin, high-density foam pads are placed where vibration is transmitted to the hand (base of the palm, thenar area) to reduce microtrauma without diminishing lever feel.
