  900 x 900	1060 x 1060
  1000 x 1000	1160 x 1160

• Available cover loads:

  Available cover loads According to DIN EN 124:1994)
  Areas inaccessible to motor vehicles	A15 15 kN – 1,5t
  Footways, pedestrian areas	B125 125 kN – 12,5t

• Used in cases when the cover surface is designed to be equal to the floor area on which the cover is installed (when the floor is covered with tiles, stone, granite, marble, laminate), used to maintain floor architectural esthetics.
• In situation where there are longer channels that have to be shut, covers are installed in series

• Cover is lowered and filled with concrete filling with appropriate reinforcement. On the bottom part of the cover there is a rectangular shaped seal made of foam rubber used to ensure watertightness and gastightness. In the standard installation, cover is tightened in the angles using four inbus screws, ensuring that seal fits the frame perfectly.
• In the standard installation, frame is made of EPDM rubber. When additional waste water resistance is required, seal is made of NBR rubber.
• Due to better contact with concrete, during installation frame has appropriate anchor wings on it.
• Cover is made according to DIN EN 124:1994 standard, „Gully tops and manhole tops for vehicular and pedestrian areas"

Basic measures

• Light opening sewage cover standard dimensions:

  SQUERE COVER DIMENSIONS
  500 x 500	630 x 630
  600 x 600	730 x 730
  700 x 700	830 x 830
  800 x 800	930 x 930

• These covers are appropriate only for the zone without any load, for shutting revision manholes in sewage systems or drinking water systems. Covers are made of profiled sheet, 3mm thick.

• Constructed for installation on: manholes for waste or drinking water, ventilation chambers, pumping shafts and other facilities.
• When there is a necessity for closing channel or some other kind of bigger opening, covers are installed in series, one next to another

• Cover is made of stainless steel sheets, due to additional stiffness, lifted on the diagonals
• At the frame's edge, between the cover and frame, profiled seal is installed. Also, between frame and concrete base, there is a rectangular seal made of foam rubber. Both seals ensure watertightness and gastightness.
• In the standard installation, frame is made of EPDM rubber. When additional waste water resistance is required, seal is made of NBR rubber.

EKOguard COV 5

• Available dimensions:

  A - LIGHT OPENING LENGHT	500 – 1000 mm
  B - LIGHT OPENING WIDTH	500 – 1000 mm

• Available cover load:

  Available cover load (According to DIN EN 124:1994
  Areas inaccessible to motor vehicles	A15 15 kN – 1,5t
  Footways, pedestrian areas	B125 125 kN – 12,5t
  Gully tips in kerbside channels	C250 250 kN – 25t
  Carrigeways of roads - heavy duty	D400 400 kN – 40t

• Covers are installed in the areas with traffic load, exposed to load from vehicles or pedestrians. Depending on installation location, appropriate cover is installed.
• When there is a necessity for closing longer or wider channels, covers are installed in series, one next to another

• Cover frame is installed into concrete, with the cover top in level with surrounding surface. On the frame's outer rim, there are anchor plates used to additionally ensure quality interaction between concrete and frame. This part is important because the entire load is transferred over the cover and frame to the concrete.
• On the bottom side of the cover there is foam rubber seal ensuring water tight ness of cover to the frame. Cover is also equiped with a lock, with the optional special key.
• In the standard installation, seal is made of EPDM rubber. When additional waste water resistance is required, seal is made of NBR rubber.
• With covers with capacity over 125kN and more, due to additional cover weight, gas springs are installed on the bottom side of the cover in order to enable single handed opening.
• Cover is made according to DIN EN 124:1994 standard, "Gully tops and manhole tops for vehicular and pedestrian areas"

EKOguard COV 7

Basic measures

• Available dimensions:

  AVAILABLE COVER DIMENSIONS
  LIGHT OPENING DIAMETER D (mm)	FRAME OUTER DIAMETER D1 (mm)
  Ø600	Ø840
  Ø700	Ø940
  Ø800	Ø1040
  Ø900	Ø1140
  Ø1000	Ø12

• These covers are used for shutting revision concrete manholes under pressure (for example: in pressure sewage systems)
• Construction for installation in: drinking and waste water manholes, pumping stations and other facility shafts

• Cover seal is square profile rubber seal; EMDP or NBR; 60 ShA, ensuring watertightness and gastightness in the cover-frame connection.
• On the bottom side of the base round frame, there is a flat seal with rectangular profile, used to ensure sealing between round cover frame and concrete base.
