Notes:
1. For continuous spans, use continuity factor = .80
**2. This distribution results in larger grating sizes for lighter trucks on
shorter spans. If H-20 loading is specified the worst condition should
be used as the design criteria
3. The fork lift wheel loads and load distribution patterns depicted
above, generally, and only partially, represent the broad range of
rubber-tired lift trucks available. For those applications falling
outside of these examples, please contact Brown-Campbell
4. Wheeled vehicles with urethane tires should NEVER be used in
conjunction with open grid bar grating |
