Waugh's Patent Tank and Dam Excavator - Ilfracombe, Queensland
The machine power is 2 1/2 horse power vertical engine and boiler, and with it the blocks containing a little more than half a cubic yard are being cut out and placed in the carts in 40 seconds, each cart taking 2 blocks, the total loading time being 1 minute 40 seconds. This speed could be increased if only clay was encountered: and with a larger machine, say of 3/4 and 1 1/4 cubic yard capacity (driven by a 4 to 6 horse power engine), he will be able to load carts at the average rate of 60 loads per hour without difficulty
