Eroding a broken contra-weight bolt of a linde motrac container truck. This M36 bolt was in 34 cm deep with a hardness of 12.9. The tools for removing were placed 80 cm from the broken bolt. After eroding a square hole we were able to remove it from the counterweight. The other option was removing the 14 ton counterweight and transporting it to a specialised repair unit.
