1. GLOSSARY
Breaking Strain: The average load at which a new component (for example: a cable or chain
assembly) will fail. The breaking strain is obtained by applying direct
tension to a component at a uniform rate of speed, in a testing machine.
Chute:
A series of linked chute sections that are used to convey debris.
Chute Hoist:
An engineered device that has been designed specifically to raise, anchor,
and lower a chute. A chute hoist consists of a support frame and a winch
apparatus. The support frame, with the winch apparatus removed, can also
be referred to as a chute hoist.
Chute Sections: Modular conical tubes that can be linked together in series to form a chute.
Chute System:
A suspended chute and the anchors (including chute hoists) that support it.
Design Factor:
Also known as the “safety factor”, it is a product’s theoretical reserve
capacity. The design factor is calculated by dividing the Breaking Strain by
the Working Load Limit. The design factor is generally expressed as a ratio,
for example: 10 to 1, or 10:1.
Working Load Limit:
The maximum load which can be applied to the component, when the
component is new, or in “good as new” condition, and when the load is
applied in-line, with respect to the centerline of the component. This term
can be abbreviated to WLL.
