An industrial cart system and method for operation thereof. The industrial cart system comprises a mother cart and a daughter cart. The mother cart comprises an upper frame and a lower frame. According to an embodiment, the lower frame is configured to support the daughter cart in a loaded or travel position. The lower frame is further configured to allow two-way loading and unloading of the daughter cart. According to another embodiment, the mother cart comprises a chassis and one or more lift mechanisms operatively coupled to the lower frame. The chassis is configured to support the daughter cart and the lift mechanisms are configured to lower and raise the chassis (and the daughter cart) to facilitate the loading and unloading of the daughter cart.
