Abstract

The double triangular heavy duty manhole cover and frame may be for carriageway locations and has special bearing shoes (6) which increase the effective cover (3) to frame (1) bearing areas. The shoes (6) receive feet (9, 10) which project down from the covers off it at each corner of the triangular leaves (3A, 3B). A double shoe (6) is provided a where leaf (3A, 3B) corners come together and a simple shoe at the remaining two lead corners. The invert of each shoe socket (12) may be concavely curved (11), and the undersides of the feet (9, 10) are convexly curved to a similar radius. The shoes may be loosely attached to the cover leaves by post-bent cover lugs engaging shoe eyelets and the base of the shoe (6) may be locally spiked (15, 16) to prevent it sliding relative to the frame (1).
