2. Wire Rope

  • Wound from high strength metal strands designed for long life and low wear
  • Available designs: steel, stainless steel for corrosion resistance, and rotation resistant
  • Minimum of 5:1 safety factor of all wire ropes
  • Electrolift chooses the type of wire rope for each hoist based on specific application

3. Wire Rope Drum

  • Spools and unspools wire rope on helical groove to lift or lower load blocks
  • Helical grooves on drum prevent the wire rope from overwrapping
  • At least 2 dead wraps remain on the drum when the rope is unwound during normal operation
  • Drum/rope diameter is optimized to reduce rope flex, reducing wear and extending rope life
  • Special features available:
    • Deep grooving
    • Rope guide
    • Quick disconnect wire rope dead-ending
