10-tonne pneumatic chain hoists were recently hired from Kennards Lift & Shift for use on a multi-billion dollar road infrastructure project in Brisbane, Australia.

Following a major investment in new pneumatic chain hoists, Kennards Lift & Shift stocks units of up to 16 tonnes for hire.

Eight 10-tonne air chain hoists that would normally require a major investment to purchase are among the new additions to the existing range.

Pneumatic chain hoists also available for hire by Kennards include 1-tonne, 2-tonne, 3-tonne and 6-tonne chain hoists with lifting heights up to 60 metres.

Six 10-tonne pneumatic chain hoists were recently hired from Kennards Lift & Shift in Brisbane for work on twin tunnels, which are part of Australia’s largest road infrastructure project.

The $4.6 billion combined road and busway in Brisbane’s north includes Airport Link, Northern Busway (Windsor to Kedron) and the Airport Roundabout Upgrade.

Thiess John Holland (TJH), a joint venture between Thiess and John Holland Group was selected as the contractor to design and construct the world-class project.

Large TBMs (tunnel boring machines), each about 165m long with a cutter head measuring 12.48m in diameter are being used on Airport Link.

Chris Ashton, project engineer for the tunnel construction says that the pneumatic chain hoists were used in the dismantling of temporary concrete segmental tunnel rings, which were built to launch the two 12.48m diameter TBMs.

While the larger segments weighed eight tonnes each, the smaller keystone segments weighed three tonnes.

Overall, 42 segments including six keystone segments needed to be removed. A monorail system, installed by TJH was used to move the hoists over the respective lifting position for each segment.

Two hoists were used per segment with two leg chains so that the segment was lifted with four points of contact.

Chris said Kennards Lift & Shift provided the pneumatic chain hoists while lifting tackle was supplied by TJH.

Christ comments that air hoists are a lot more efficient and easier to use. Since they are also expensive to buy, it is better to hire them.

Chris said Kennards Lift & Shift was chosen as a supplier based on their ability to provide six identical air hoists in addition to price and service advantages.

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