Mechanical Installation
Installation Guidelines
• The rope should be easily accessible and visible along its entire length. Markers or flags may be fixed on the rope
to increase its visibility
• Mounting points, including support points, must be rigid and allow sufficient space around the rope to allow easy
access
• The rope should be free of friction at all supports. Pulleys are recommended
• The rope may not be routed around a corner, for this model.
• Never run rope through conduit or other tubing
• Never attach weights to the rope
• Temperature affects rope tension. The wire rope expands (lengthens) when temperature increases, and contracts
(shrinks) when temperature decreases. Significant temperature variations require frequent checks of the tension
adjustment
• Do not exceed the maximum specified total rope length. Banner offers models for other spans; contact Banner
