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.

McMillan Engineering Group 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

McMillan Engineering Group were contracted to design, manufacture and supply a wide range of custom cylinders, power units and hydraulic accessories for the Urban Superway Project in Adelaide, South Australia.

In 1999 a development was planned for the historically significant Wales House building in Sydney. An extra floor was required which meant the 915T cupola needed to be raised 3.9m. Since dismantling the cupola was nut possible the decision was made to raise the cupola via the use of hydraulics. The cupola was raised and supported 1.3m a night over three nights.

McMillan Engineering Group designed and manufactured 12 hydraulic cylinders, a hydraulic power unit and a control panel to achieve this engineering feat.
