A mixing drum in the concrete plant
A massive drum, its surface crusted with dried concrete, sits tilted in a heavy iron frame with a thick axle and levers; a timber gallery and stairs run overhead, and cables cross in front of it. It appears to be one of the mixers of the concrete plant, which supplied the dam with concrete around the clock.
