Use shelters with loading doors larger than 2.8 m wide or 3.0 m high. Also use them for trucks with extended tailgates or rear platforms.
When specifying rigid frame shelters, also follow these application guidelines: |
 |
 |
 |
 |
The normal minimum shelter width is 3.3 m, measured across the side frames. The standard opening width of a shelter is 2.1 m, measured between the insides of the side curtains. Side by side shelters can have common side frames. |
 |
 |
Set the bottom edge of the top curtain 15 cm below the height of the typical truck serving the facility (Fig. 50). |
 |
Design shelters to project 30 cm to 40 cm in front of the dock bumpers (Fig. 50). For shelters wider than 3.6 m, increase the shelter projection by 1 cm over the minimum recommendation for every 2 cm of additional shelter width. |
 |
Shelters have steel support brackets which protect and support the side members. Mount these brackets on the building foundation. Install the brackets flush with the dock floor and have them project 15 cm outside the shelter frames. |
 |
For unique applications, consider shelters with spring loaded frames and inflatable sealing members. |
