Every building which faces or abuts upon a public alley where freight, goods and other commodities are loaded or unloaded through rear doors onto and from any vehicle, shall be equipped with a movable, rolling, folding or collapsible platform, so that such vehicle may stand parallel with the building from which said loading or unloading is done; provided, however, that whenever it may not be practical to load or unload any vehicle when thus placed in a parallel position to any building by reason of large, bulky, unwieldy or cumbersome freight, goods, or other commodities required to be loaded or unloaded, such vehicle may then be placed in a crosswise or cross-alley position.
Whenever the work of loading or unloading such freight, goods or other commodities onto or from any vehicle from such platform is completed, such movable, rolling, folding or collapsible platform shall be removed into the building from which the loading or unloading was done.
