5.4 Car stacker spaces

The proposal seeks to provide 14 office car spaces via 7 x Dependent car stacker
systems. A Dependent System is the simplest form of car stacker, where the lower car(s)
need to be moved in order to retrieve the upper car(s). This mechanism enables
accommodating two cars in the one car parking space above ground. The platform has
a maximum lifting capacity of 2700kg and it can be stopped at different heights to
accommodate various vehicles & ceiling heights.

Hercules car parking systems have identified “Hydro-Park 1127: 2.0m SUV” as a viable
option for this site. Figure 6 illustrates this system. It is noted that this system has been
designed to comply with the Australian Standard AS 5124:2017 (Safety of machinery -
Equipment for power driven parking of motor vehicles).

The key dimensional requirements for this system are as follows:

   1) Total width per space between centreline of columns = 2.58m
   2) Total length per space = 5.5m
   3) Aisle width (in accordance with AS 2890.1) = 6.1m
   4) Total headroom clearance (upper level to be used by a Sedan while the lower
       level to be used by an SUV) = 2.1m (for the SUV at the lower level) + 0.124m
       (platform thickness) + 1.7m (for the Sedan at the upper level) = 3.924m

The site plan with key dimensions shown in Figure 5 illustrates compliance with the
dimensional requirements identified in Items 1-3 above. The headroom clearance
requirement determined in Item 4 above has been satisfied in the proposed design, as
shown in Figure 7.


5.5 Blind aisle clearance

AS 2890.1 requires the end of the vehicle aisle to be extended by an additional 1m
beyond the last car space (so that the vehicle using this space can reverse out into the
extended aisle area for forward exit). The proposed design provides an aisle extension
of 1m length, beyond the last car stacker space (see Figure 5).
