Manhole covers of this load capacity are specifically designed for installation in green areas, pedestrian zones, and parking areas for passenger vehicles, where heavy-duty vehicles are restricted from entry. The height of the manhole cover frame allows for easy installation in areas with laid-out sidewalk tiles. Additionally, the medium-sized manhole cover can be equipped with an intermediate cover featuring an opening for a gas analyzer. Please note that a locking device is not included with this type of manhole cover.
