Vertical Access Construction Hoist Scando 20/32 from Alimak Hek

Alimak Hek provides access to basement
excavation site at Watpacs' One Central Park.

One Central Park is the landmark first residential stage of Watpac Constuction's $2 billion Central Park Precinct development. Located in downtown Sydney, One Central Park East tower will stand at 33 stories, while the West tower will stand at 16 stories, comprising a combined total of 623 residential apartments. A further five levels of basement car parking will cater for more than 1,200 vehicles. Construction of One Central Park commenced in December 2010, and is due for completion in early 2013.

Alimak Hek installed a Scando 20/32 on site at One Central Park, providing safe and efficient vertical access to the five basement levels during construction of the underground carpark. The challenges during installation were the absence of any structure to which the hoist mast could be anchored and a 13m gap between the hoist and ground level embankment.

Alimak Hek engineered a 13m platform to bridge the gap between embankment and hoist. This platform was supported by an additional mast and allowed men and materials to traverse the 13m expanse from ground level to hoist. The Scando 20/32 hoist was then used to transport workers, equipment and materials down five levels into the excavation site.

The addition of the Alimak hoist improved site safety, eased manual handling and sped the construction process by swiftly and efficiently transporting men and materials between the ground-level embankment and below-ground construction site.

Alimak Scando is the world's most popular and widely used passenger/materials construction hoist. Available in single or dual car configurations the Alimak Scando reaches lifting heights of 400m and speeds of 100m/ min, with a maximum supportable payload capacity of 2,800kg.
