mobile entrance aid for manholesMobile climbing aids (mobile ladders) for square and round pits (manholes)

In Germany since 1994 in accordance with GUV 7,4. & 5, Abs. 11 permanently installed ladders required suitable holding devices at waste water-technical plants.

We offer a mobile ladder for manholes as an alternative to the expensive re-tooling of pit entrances with stationary holding devices. It can be mounted in all square and/or round pit entrances without a step. The mobile climbing aid is designed to be carried on maintenance vehicles and is used every time a worker needs to enter a manhole or a drain.
