Standard-compliant frame

Manhole covers and load classes – DIN EN 124

The requirements governing manhole covers and gully tops for vehicular and pedestrian areas are regulated in DIN EN 124 / EN 124-1:2015. This sub-divides covers into load classes A15 to F900 and defines areas of application (pedestrian zones, areas where vehicles have access, heavy industry).

Langmatz QaBo polycarbonate manholes are designed for load class D400 and have been tested as a complete system (body + frame + cover). They thus meet the requirements for roadways, car parks, and vehicular areas.

Classification according to areas of use and DIN EN 124

asset_image

A 15 – 15 kN test load

Areas used exclusively by pedestrians and bicycles, and similar surfaces, e.g. green spaces (Group 1)

asset_image

B 125 – 125 kN test load

Pavements, pedestrian areas, and similar surfaces, car parks and parking decks (Group 2)

asset_image

C250 – 250 kN test load

Parking spaces, shoulders, and gutter areas, extending a maximum of 0.5 m into the roadway from the curb edge and a maximum of 0.2 m into the sidewalk (Group 3)

asset_image

D 400 – 400 kN test load

Road carriageways (including pedestrian streets), parking areas, and similar permanent traffic surfaces, e.g. AOD parking areas (Group 4)

Locking mechanism

Manhole covers with load class D400 must always be screwed down, locked, or secured by a surface-re lated mass in accordance with DIN EN 124.

European Technical Assessment – ETA and EEAS

Langmatz QaBo polycarbonate manholes carry a European Technical Assessment (ETA 18/0734 for PC) based on a European Assessment Document (EAD), confirmed by the European Organisation for Technical Assessment (EOTA).

Key points:

  • Proof of load-bearing strength in different load scenarios
  • Testing of resistance to horizontal forces (e.g. brake loads on the cover)
  • Durability tests (environmental influences, UV, temperature, fire behaviour, chemicals)
  • Overall assessment of the manhole body and cover in accordance with DIN EN 124, load class D400
  • CE marking and associated Declaration of Performance

This provides systemic proof for the complete manhole system, and not just for the cover.
