STEEL ROPE REQUIREMENTS
Recommended Wire Rope – Compact 1000, 1250 & 1500
Sky Climber has found the 5/16”, (8.0 mm) 5-strand wire rope to be the most effective for trouble-free
operation. Please use only that rope which is recommended by the manufacturer.
Product
5/16” (8.0 mm) 5 x 26 WS, PFC, G, XIP, RRL, performed, break strength at 10,500 lbs.
Compliance
Use only the specified wire rope in the Compact 1000, 1250 &1500 Hoist. If further information is needed,
please contact Sky Climber at 740-203-3900 or 800-255-4629. All wire rope used must conform to
Federal Specifications RR-W-410P Type 1, General Purpose, Class 2. The supplier should provide a
Certification of Breaking Strength proving a minimum strength. The wire rope MUST have a breaking
strength at least six (6) times the rated load of the hoist (6:1 Design Safety Factor). This rope is resistant
to abrasion and crushing with medium fatigue resistance.
WS Warrington Seal PFC Polypropylene Fiber Core
G Galvanized XIP Extra Improved Plow
RRL Regular Right Lay Steel
Tipping and Braising
Braze a wire rope tip by applying braze to approximately 1/2 inch of tip (do not
exceed 3/4 inch) and let it glow to all of the individual wires. Let the rope AIR
COOL. Air cooling is very important. Then grind the tip to a taper, but not a point.
Tip should resemble a pencil with the lead broken off.
How to Check for Proper Wrapping
Cut 50 to 100 feet from your new spool of specified wire rope. Braze both ends
and run it through a hoist 10 times (no load needed). Check if the strands are
separating above or below the hoist. If they DO appear to be opening, then the
strands are improperly wrapped and will result in hoist jamming. Return the spool
to your supplier.
Quality
Wire rope must be of good quality and free of damage or defects (see Wire Rope Inspection in
this manual). The wire rope must be inspected every day by a competent person.
