    Leyland DAF medium mobility load carrier (MMLC) Foden improved medium mobility load carrier (IMMLC) Both were able to transport 15-tonne flatracks or containers configured to ISO 20 feet standard and to load and offload them autonomously. Both may have been supported with side rail transfer equipment (SRTE) for loading and unloading railway wagons.

  3. Roof rack - Wikipedia

    en.wikipedia.org/wiki/Roof_rack

    When installing roof racks, it is essential to load the bars properly per the owner's manual. When driving on the road, one needs to load the allowed weight minus the weight of the roof rack kit. If one plans to use the roof racks for off-road driving, the allowed weight should be divided by 2, and this will be the maximum amount to be carried ...

  4. Load-bearing wall - Wikipedia

    en.wikipedia.org/wiki/Load-bearing_wall

    A load-bearing wall or bearing wall is a wall that is an active structural element of a building — that is, it bears the weight of the elements above said wall, resting upon it by conducting its weight to a foundation structure. [1] The materials most often used to construct load-bearing walls in large buildings are concrete, block, or brick.

    The roof of this industrial building is supported by a space frame structure. If a force is applied to the blue node and the red bar were not present, the resultant effect on the structure would depend entirely on the blue node's bending rigidity, i.e. to its resistance (or lack thereof) to bending; however, with the red bar in place, then assuming negligible bending rigidity of the blue node ...

    They are designed as simple spans supporting equally spaced concentrated loads for a floor or roof system. These concentrated loads are considered to act at the panel points of the Joist Girders. These members have been standardized for depths from 20 to 120 inches (510 to 3,050 mm), and spans to 120 feet (37,000 mm).

    roof load; wind load; Previously, it has been shown that the limit state design/load and resistance factor design (LRFD) and permissible stress design/allowable strength design (ASD) can produce significantly different designs of steel gable frames. [3] There are few situations where ASD produces significantly lighter weight steel gable frame ...
