Abstract: The presently disclosed embodiments, as well as features and aspects thereof, are directed towards providing a modular cart system operable in multiple configurations suitable for multiple transport applications and, more particularly, for a modular cart system that includes a multi-purpose chassis member. Advantageously, embodiments of a multi-purpose chassis member include various features that provide for either the receipt of a component included in a modular cart system or, alternatively, mechanical coupling to fixtures that are exclusive from the modular cart system. Importantly, because a multi-purpose chassis member is configured for the receipt of various components that may or may not be comprised within a given cart arrangement, a modular cart system that includes a multi-purpose chassis member can be reconfigured for a custom transport solution depending on application.
