A little while ago, Graham Giles wrote in to say that two speed cranes used at Canberra made launch and retrieval more controllable. Graham has just sent this photo plus their design plans….
The crane at Canberra is not materially different to the Freshwater Bay one, except that it is a commercial 1 tonne design, with a deep foundation (due to the lakeside surface material being fill) and therefore not requiring support struts. It can accept boats on both sides and is hand slewed with a 3 position slew lock. The hoist is a GIS GCH 1600SF with 12.5 and 3 metres/minute hoisting speeds.
