Port Miami Tunnel Project

IHS-0300-06-DA-SR

The Port Miami Tunnel Project formed two 1.2km, 2 lane tunnels to form an alternative link to Dodge Island via the MacArthur Causeway on Watson Island.

IHS supplied eight 300T double acting safe rams to facilitate the lifting of the 13.1m diameter tunnel boring machines. Via the use of internal porting we were able to design these rams with 150mm stroke and only 430mm closed height.

Specifications

  • 301T Lifting capacity @ 690 bar
  • 150mm Stroke
  • 600T Capacity mechanical lock ring
  • Double acting
  • Spherical load cap
  • 430mm Closed height
  • NATA Force Calibration
