INSTALLATION (continued)
SLACK RESTRAINTS
If the restraint intervals will be more than 25 feet (8 m), use slack restraints to secure the chute
to the building structure. Slack restraints keep the chute from acting like a taut sail by allowing
it the freedom to form an arc and move up and down. Do not mix slack and taut restraints.
The attachment of the chute’s discharge end to the container (or other anchor) must be
considered a restraint. Use Container Cord. Do not tie it tightly as the chute must be able to
move if heavy winds arise.
If the wind strengthens, the strain could cause the Superchute
®
Container Cord to fail, which is
beneficial, as the chute will be released and failure of the hoist will be avoided.
NO WIND
WIND
• When subjected to wind, the
chute is able to move freely.
• The restraints allow the
chute to rise.
• Additional downward forces
are not exerted on the hoist.

The sketches on this page show the correct application of restraints.
• Spacing greater than 25 ft. (8 m)
• Use SLACK restraints.
• In this case, the Container
Cord was tied to the lamp
pole to provide more slack
for chute movement.
