Most of us rarely notice them, and although they can bravely be run over by a truck in extreme weather for 100 years without deterioration, we rely on their robust operation to keep us from falling into open sewers.
They are almost everywhere, all over the world, under our feet, on every block, on every street corner: manhole covers, stormwater inlet grilles, bumpy rectangles where sidewalks meet streets (formally known as detectable warning signs), etc. Wait.
We should not underestimate the weight of cast iron manhole covers and the difficulty of opening them. They rattle when vehicles pass them, but the manhole covers are heavy. Removing one at your own risk can lead to serious back, neck or spine injuries. Safety should always be a top priority. The cover is rough, rusted, and sometimes has sharp edges. Make sure you wear heavy duty gloves to protect your hands from injury when lifting the manhole cover. Pay close attention to keeping your hands away from the pinch point. Also, make sure to step over the manhole cover and lift your back straight and your knees bent. Hydraulic jib cranes work better, but cost more.
Installing light manhole covers and having the right tools to do the job safely is our goal. Loosen the fixing hole with a screw tool, and fasten the lifting hole with a manhole lifter (manhole key). Manhole keys come in a variety of sizes and styles. The multitasking tool can also lift composite manhole covers. Start by making sure the edges of the cover are free of dust, debris, or other deposits that can cause the cover to get stuck in the hole, making it more difficult to move. Using a hammer can break the lid, which is expensive and dangerous.
I hope these comments can help you to install manhole covers safely.
