  • Page 76 Section 6 - Maintenance Replace any wire ropes that have been abraded, crushed, kinked or twisted. Wire rope should be routinely cleaned monthly of any and all debris. Grit and gravel can quickly reduce a wire ropes life. A wire rope should be well lubricated so that it can act and perform as it was designed.

  • Page 77: Wire Rope Installation

    Section 6 - Maintenance WIRE ROPE INSTALLATION Proper Unreeling Procedures Wire rope can be permanently damaged by improper unreeling or uncoiling practices. The majority of wire rope performance problems start here. Improper unreeling practices lead to premature rope replacement, hoisting problems and rope failure. Place the payout reel as far away from the boom tip as is practical, moving away from the chassis.
  • Page 78 Section 6 - Maintenance Drum Winding When wire rope is wound onto a sheave or drum, it should bend in the manner in which it was originally wound. This will avoid causing a reverse bend in the rope. Always wind wire rope from the top of the one reel onto the top of the other. Also acceptable, but less so, is re-reeling from the bottom of one reel to the bottom of another.
  • Page 79 Section 6 - Maintenance Keep Wraps Tight The end of the rope must be securely and evenly attached to the drum anchorage point by the method recommended by the equipment manufacturer. At least fi ve wraps of wire rope must remain on the drum as dead wraps when the rope is unwound during normal operations.
