THE CABLE ASSEMBLY (continued)
WHY IS WIRE ROPE USED IN THE CABLE ASSEMBLY?
"For general construction rigging never use a chain when it is
possible to use wire rope. The failure of a single link of chain can
result in a serious accident but wire rope on the other hand is
frequently composed of 114 wires, all of which must fail before the
rope breaks. Wire rope gives you reserve strength and a chance to
notice a hazard, chains do not."
Rigging Manual, CSAO, 1996
There are many advantages to wire rope:
Wire Rope Chain
Provides warning when worn No visible warning before failure
Consistent strength Inconsistent strength – except the high quality grades
Lightweight Heavy and bulky
The many strands create a multiple
point suspension system Single point suspension: Lose a link – lose it all.
Chain is only as strong as its weakest link.
Occasionally Superchute ® will use chain in cases where adjustment is required. For
example: Door Adjustment Kits and chute hoists. However, only high quality Grade
70 and Grade 80 chains are ever used.
The three dots on the pressed sleeve
are Superchute’s
® identifying mark.
This mark has been in effect since
March 1998.
