Superchute Tremie & Funnel Support
STRENGTH OF THE WIRE ROPE LINKING SYSTEM
Every tremie section is equipped with 2 galvanized cable assemblies.
Destruction tests have shown the Breaking Strain of a cable assembly to be approx. 10,000 lb.
Therefore a tremie section has an ultimate load rating of 20,000 lb., i.e. the paired assemblies will break if they are subjected to more more than 20,000 lb of load. This information applies to Superchute® cable assemblies in new or “good as new” condition, that were supplied with the Superchute® tremie.
Your site engineer must
determine a safe Working Load Limit (WLL) for the system. If there are people
working under a suspended tremie, then your engineer will likely require a safety
factor of 5 to 1, or greater. If there are no people working under or near the
suspended tremie, then the engineer could possibly require a safety factor as
low as 2 to 1.

WARNING! Do not use the funnel to support the tremie sections hanging below. It is not strong enough. Use the cable assemblies or U-bolts of the uppermost tremie section to support the weight of the tremie sections hanging below.
Simply sit the funnel on top of the suspended tremie. To prevent the funnel from being knocked off the the tremie, the funnel should be attached to the tremie using the supplied chain & hook assemblies.
|The same funnel is often used by contractors for elephant trunking as well.|
