instructions and comply with inspection and
maintenance requirements.
Any use other than specified is unintended. The
manufacturer shall not be liable for damages
resulting from unintended use.

serious danger. Never
• use rigging frames to exert diagonal force or
tension on loads,
• use a crane to dislodge stuck or immovable loads,
• lift people,
• strike, knock or dent rigging frames,
• heat-treat or weld rigging frames,
• exceed the truss’s maximum load-carrying
capacity
Note that in addition to the above specifications,
