Abstract
Abstract A product testing system comprises a housing with at least one opening therein, the housing having an internal, environmentally controlled chamber. Products to be tested are mounted to a product carrier. The latter is carried, in turn, by a product carrier transfer assembly. By means of the vehicle and transfer assembly, the product carrier may be oriented to be received within the housing opening with the products exposed to the environmentally controlled internal housing chamber. In one embodiment, the vehicle traverses a path adjacent one or more housings, and the product carrier transfer assembly rotates, elevates and laterally moves the product carrier to position it in an opening in the housing.
