A new hydraulic cassette type torque wrench hired from Kennards Lift & Shift saved hours of work for a construction company while carrying out repairs to a storm damaged, heritage listed retaining wall.

Ground engineering and construction company, Retaining Specialists hired the torque wrench from Kennards Lift & Shift for the project at James Fletcher Hospital in Newcastle.

The retaining wall was damaged by storms that struck the city in June 2007, flooding hundreds of homes and even forcing the 76,741-tonne bulk carrier Pasha Bulker aground on Nobbys Beach.

Repairs to the 150-metre long sandstone and brick retaining wall at James Fletcher Hospital were preceded by substantial geotechnical investigations, heritage consultations and detailed design work.

Retaining Specialists secured the structure with 300 anchors, which were driven through the wall and grouted into the ground behind. The nuts securing the anchors were torqued to 9 tonne (2400psi) in the bottom section of the wall, and to 6 tonne (1500psi) in the upper section.

Retaining Specialists operations manager Kim Dellosta said the torque wrench was excellent for securing and calibrating the required tension. A hollow core jack would have achieved the same result, but in a slow and tedious way.

The easy-to-operate 240V torque wrench allowed the work team to complete up to 15 anchors an hour, instead of two or three the conventional way. Additionally, the torque wrench from Kennards Lift & Shift wrench came fully tested and certified.

Retaining Specialists had previously used the torque wrench on a project in Melbourne and were aware of the benefits.

The hydraulic cassette type torque wrenches are quite expensive and it is better to simply hire them.

Key advantages of the torque wrenches:

  • More compact than standard square drive torque wrenches
  • Does not involve the use of bulky sockets
  • Operates via a link that is altered to the size bolt in the application, making it suitable for restricted access areas

Kennards Lift & Shift operates hire centres in Brisbane, Sydney, Wollongong, Melbourne, Adelaide and Perth.
