Abstract (en)
[origin: EP0399955A2] The grating has a means for securing it against jumping out when crossed by a vehicle. For this purpose, on one side face of the grating (1) a part (2') of its supporting element is designed as a thin tongue-shaped wall (33) with an outer thickening (34). The supporting element has a notch (35), extending perpendicularly to its longitudinal axis, at each end of the tongued-shaped wall (33), a thickening (22) and/or an indentation being present on one inner side face of the associated supporting frame (2, 2'). <IMAGE>
