An inspection of the underground housing (1) is possible when the blocking element is in a fully
raised position. It is not necessary to enter the Wedge. In case there is a need for entering the
barrier fix the blocking element in the raised position to prevent any accidents.
The Wedge is an open steel structure. Depending on environmental conditions a more frequent
cleaning of the underground housing may be necessary.
