Heavy Duty 600X600 Sewer Manhole Cover Frame moulds

Every industry has its own standards, and of course the manhole cover mould is no exception. Don't underestimate the manhole cover mold. Anyone who has experienced the loss and damage of the manhole cover mold knows that it is the guardian of everyone's life. So, what are the standards for composite manhole cover molds?

The manhole cover mold must have a certain load-bearing capacity, and it is not easy to be damaged. How many accidents would it cause if it deformed as soon as it was pressed! The manhole cover mold should be anti-noise, which requires the contact occlusal surface of the manhole cover mold and the well ring to directly act on the T-shaped rubber strip to overcome the rigidity and eliminate the noise. The anti-vibration of the manhole cover mold is by setting a U-shaped groove at the stop of the well ring, using T-shaped synthetic rubber strips, embedded in the U-shaped groove, in the process of contact between the manhole cover mold and the well ring, to play a buffering role, reduce Vibration force. Of course, it needs to be slip resistant. The surface of the manhole cover mold uses a raised 3mm pattern to prevent slippage and avoid accidents.

It also needs to prevent displacement. Four rivet bolt holes are reserved in the well circle, which are evenly distributed at 90 degrees. Each set uses 4 ground anchor bolts to avoid displacement due to mechanical rolling during road construction, and Played a certain anti-theft effect. Since cast iron manhole cover molds are often stolen, many safety accidents have occurred, so theft prevention has become one of the standards for composite manhole cover molds.
