Oil hydraulic system for tunnelling shields
Tunneling shields for Toronto subway project are entirely self-contained except for electric power cables brought in; two separate oil hydraulic systems are built into shield, to move it forward, erect lining segments, and adjust working platforms; two shields are 25 ft 9 in. in diam for 24 ft ID tunnels, and four are 17 ft 6 in. in diam for 16-ft ID tunnels; circuits and load balancing valve diagrams.
