Class of loading

Class of loadFully Laden(kg)Back Single-wheel Load(KN)Wheel-pressure Area a*b (mm)

Features of Drainage pit & trench cover
1) Extended life from hot dip galvanizing
2) High hydraulic efficiencies due to maximum waterway created by narrow load bars Secure anchoring of frame in concrete from out turned frame angles and deformed steel rod anchors
3)Safe installation arising from low frame and grating weights
4)Safe opening and closing due to low weights and the availability of grating hinging
