The Haulage was created to move ores from the Hercules Mine on Mount Read.[4] The mine was operational between the 1890s and the 1980s, and closed in 2000;[5] rehabilitation works commenced in 2005.[6]
The Haulage
The haulage was "self acting",[7] one mile (1.6 km) long and 1,642 feet (550m) high with a maximum gradient of 1 in 5.[8] It was claimed to be the largest and steepest self-acting tramway of its kind.[9][10]
Later haulage
On the closure of the NE Dundas Tramway, the Aerial Ropeway[11] from Hercules was built which took ore in a northerly direction to Rosebery, some literature confuses the two separate systems.
^Light Railways, number 35 Autumn 1971 p.22 has the gradient average as 1 in 3.2, and a maximum of 1.5 with operating speed of 14 mph – further details in Light Railways number 27, page 25 by Wayne Chynoweth
^NOTES ON SELF – ACTING TRAMWAY, THE HERCULES MINE, TASMANIA.(A paper read before the Sydney University Engineering Society, November 12th,1902. By.B. SAWYER, B.E.)
The Hercules Mine, situated on the western slope of Mount Hamilton, a spur of Mount Read, is connected with the terminus of the North-East Dundas Railway at Williamsford by means of an inclined self-acting tramway-on the endless rope system.
The slope length of this line is eighty and a half chains, and the difference in elevation between the Government line and the "send-off" at the Mine is 1,642 feet. The average gradient is, therefore, 1 in 3'2, the maximum gradient being 1 in 1'5, and the minimum, i.e., the approach to Williamsford terminus, 1 in 8-8. source: http://escholarship.usyd.edu.au/journals/index.php/SUES/article/.../2239[permanent dead link]
