Recent Project: Clean Room Bridge Cranes
Turnkey pair of 2-ton capacity clean room bridge cranes capable of very carefully and accurately positioning components during the assembly of an optical device on two assembly towers. This accurate positioning was obtained with hoisting speeds that ranged from .3 inches per minute to 8 feet per minute. Accurate weighing of the components during assembly was required. Since headroom was limited, we built a scale system into the hoist. We also supplied the assembly towers. We performed very accurate, certified heavy welding and finish machining, holding tight tolerances to thousands of an inch over 12' span. The platforms are 14' high x 19' wide x 12' deep and load tested to 5 tons. The cutting, welding, machining and assembly was all performed in our shop.
