Hydraulic manhole covers PARXESS
The frames of PARXESS manhole coversbenefice the LTS ®*system resulting from the industrial and scientific research (Nottingham University), and which has proven all its effectiveness with Aksess.
The frame have 8 zones of reinforced supports which create a contact large surface with all types of manhole covers or of concrete boxes thus minimizing the pressure transmitted to the matters.
The profile and the frame depth of the PARXESS manhole coversensure those a great resistance to the deformation and a great rigidity.
*LTS ®: System “Load Transfer System”enabling to increase theperformance and the security in the time of square form municipal castings.
Effective bedding: frame with notched flange.
The flange of PARXESS manhole covers frames is furnished with notches on the 8 zones of reinforced supports. To speak about the strength at the wrenching.
This notching enables to improve the strength of the bedding to the shearing forces, generated by the passage of the vehicles, by increase of the iron/sealing product contact surface.
