We bought a big hand trolley (2.4 m x 1.2 m, 1000 kg load) back in 2002, and have used it extensively since. The steel frame has been desperately in need of a de-rust and repaint for a few years now! When we had finished using the trolley as the base of the soil sifter, we removed all the wooden framing and platform and started to remove the old paint and rust with a wire brush on a angle-grinder (this was in December last year) and then we left it in the workshop until today.
We finished wire brushing and cleaning it this morning and then painted it this afternoon (we will probably only give it one coat as it really was very rusty and will need to have the platform support frame replaced in a few years (if we don’t discard it as no longer needed)).
