The lab routinely analyzes large metal castings weighing up to 20,000 lbs. each. The facility’s coordinate measuring machine (CMM) is located in a temperature- and humidity-controlled room with a positive-pressure ventilation system. The loading/unloading of the test pallet is performed in an adjoining room with a quick-rollup curtain door to limit exposure to the outside environment. Lab workers needed a way to safely and quickly transport the bulky test articles and pallet from the staging room to the CMM room.
