Why doesn’t Superchute® use chain?
For general construction rigging never use a chain when it is possible to use wire rope. The failure of a single link 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.

From The Rigging Manual, CSAO, 1996.

Great strength & safety results from using wire rope composed of many grouped wires. In fact, there are 133 wires total!

Chains are built from single links. Each link has to support the entire load alone. If a link fails you will likely lose the whole chute system with potentially fatal consequences.

The following 3 limits are for chute sections equipped with the original cable assemblies. To verify when the section was manufactured check the date stamp on the chute sections.⁽¹⁾

1. A chute section manufactured in Feb. 1999 or later and still equipped with original cable assemblies can carry a maximum of 60 sections (200 feet) or 2000 lb. of chute – whichever is reached first.⁽²⁾
2. A chute section manufactured between June 1996 and February 1999 and still equipped with original cable assemblies can carry a maximum of 30 sections (100 feet) or 1000 lb. of chute – whichever is reached first.⁽³⁾ If you would like to be able to build a taller chute (up to the limits described in “A.” above), contact the factory for retrofitting of the cable assemblies.
3. If the chute section was manufactured prior to June 1996, and is still equipped with the original cable assemblies, it can carry a maximum of 15 sections (50 feet) or 500 lb. of chute**, whichever is reached first.⁽⁴⁾
   These older cable assemblies feature lightweight metal alloy clips stamped with the words “KONG – BONAITI – ITALY”. The “KONG” clips are much weaker than the forged ones currently used. For this reason, chute sections with this clip on the cable assembly must only be used to build chute systems less than 50 feet in length or 500 lb. in weight (whichever is reached first). If you would like to be able to build a taller chute (up to the limits described above) contact the factory for retrofitting of the cable assemblies. The gate of the “KONG” clip must close fully. If the gate is not fully closed, its strength is greatly reduced.

Caution:

• The above information applies to new undamaged cable assemblies working together in pairs
• Misuse or wear and tear will reduce the strength of a cable assembly
• Maintain the safety factor: inspect cable assemblies regularly & replace if worn
• Do not mix and match with other chute brands – use the original Superchute® sections and parts only
• Section weight is stamped onto every chute section since 1997
• If you do not understand which height & weight limit applies to your chute stock please contact Superchute®

Notes:

(1) As of June 1996 the month and year of manufacture have been branded into every chute section. The month & year of manufacture is relevant only if the original cable assembly pair has not been upgraded or downgraded.

(2)(3)(4) Superchute® makes 6 chute diameters. Larger section sections are heavier and will reach the weight limit before the height limit. Before each installation calculate the precise weight of your chute system using the weight chart located in the chutes manual.
