As part of the farm sale, I had to remove 2 water tanks from the bottom of a steep slippery valley. The tanks were 2.8m high and 4,4m diameter, and weighed 1 tonne each. When full they hold 45 thousand litres of water each. i.e. they were big awkward and heavy, and easily damaged.
We pulled the first tank onto the truck tray, with a 4WD tractor. All OK, but the truck could not drive up the slippery track. Even with the tractor pulling the truck, it all came close to slipping off the track to disaster. Then my elderly farmer neighbour Des suggested using a steeper, but rocky track, and that was safely and successfully negotiated. Tank one placed in the top paddock ready for transport to the new owner.
The next tank was dug into the side of the hill, and required a couple of hours digging with a back hoe to free it enough to pull it free with the tractor.
We tried to pull it up the planks as per tank one, but the slope was steeper and the planks started breaking. So we used tractor hydraulics to do the lifting for us. See the next photo…
