Despite challenging mixed ground and fault zones, a Robbins TBM achieved advance rates of up to 605.8m in one month on the Los Condores Hydroelectric Power Project in Chile

A dedicated team, including three Robbins Field Service personnel, guided the machine to breakthrough in conditions including tuff, sandstone, breccia, and conglomerate with sections of high-pressure
