Three phase power lines above, and they work live with the SkyTrim. 23m boom. Before they acquired the new machine it took a couple of men a couple of days with chainsaws on a cherry picker, with the power off, so no leccy for most of the village! The cab tilts left and right within the wheels around 25 degrees to allow it to get around corners. The operator is very skilful, he manages to get 90% of the branches to fall in our side (great !), and not the roadside. There is a large dozer blade on the front to shove the fallen limbs in to a big pile ( for us to deal with lol).
The second operator is in radio coms directing the driver. Pretty impressive imho.
