Tietjen – as always, one step ahead with another smart idea: We added a load sensing valve from WABCO with a special adjustment unit with up to two load levels for pulled work machines, trailers and attachment - and the new requirement as per regulation (EU 167/2013) is in place. This states that vehicles registered with a speed of more than 30 km/h must meet the required brake bands in empty and loaded state.
