TERMINATING WIRE ROPE ENDS
Though most wire ropes today are pre-formed, eliminating the tendency to “explode” or fly apart
when cut, it is advisable to place sizing securely on each side of the point where a cut is to be
made. Either sizing strand or annealed wire may be used; the important point is that sizing be
drawn taut enough to prevent any strand from being even slightly displaced. Two sizing on each
side of the point where the rope is to be cut should be sufficient for all the rope sizes on Beta Max
hoists.
All wire rope shipped from the Beta Max factory with termination ends has high quality press fit
endings. Wire rope clips may be purchased from Beta Max for all of the sizes of wie rope that Beta
Max hoists require. When applying a terminating device other than press fitting, such as a wire
rope clip, follow the manufactures specifications or the following method.
1. Turn back the specified length of rope from the thimble. Apply the first clip one base width
from the dead end of the wire rope (U-bolt over the dead end — live end rests in the clip
saddle). Tighten nuts EVENLY to the recommended torque.
2. Apply the next clip as near the loop as possible. Turn on nuts firmly but do not tighten.
3. Additional clips if required should be spaced equally between the first two.
4. Take up rope slack.
5. Tighten all nuts evenly an all clips to the recommended torque.
Apply the initial load and re-tighten nuts to the recommended torque. Wire rope
will stretch and shrink in diameter when loads are applied. Inspect clips
periodically and re-tighten.
When uncoiling the rope, always roll the coil like a hoop. Never lay the coil down and throw the
rope out in loops. When this is done, kinks are liable to form and the rope becomes twisted and
hard to handle.
