How A Manhole Cover Lifter Makes Work Easy For You

By Luisa Sharpe


When lifting manhole covers, you can safely remove them using a manhole cover lifter, which is designed to pull the covers effortlessly or with minimal effort. Unseating and freeing up covers from manholes requires a significant lifting activity. Many a times, you will find that due to lack of access of the sewer lines and other underground installations for a long time, the frame of the manholes and the covers stick together.

With years of corrosion activity, the frames and covers are glued together and they cannot open easily. In addition, some of these covers are very heavy even when they are not corroded or embedded together, and they will cause problems in lifting them. The traffic passing over the covers whether vehicular or foot further pushes and exerts pressure on the parts making them to hold together tightly.

These covers are often heavy weighting many kilos. The standard practices used in the past before the invention of more applicable tools was the use of crowbar jammed into a notch that is located at the rim of the cover. By jamming the bar, a person would pry up the manholes cover and then lift using the hands.

The use of the crowbar is to ensure that griped covers are released from the seats or frames and then lifted up using the hands. These practices are still in use today and they present many challenges. If the manhole cover is too heavy, you will have problems when using these traditional techniques.

A person could strain muscles as he or she tries to pry up covers or lift them out. In addition, the notches at times are filled with tar and debris and inserting the pry bar becomes a problem. When lifted out, the manholes covers could still slip from hands and fall on feet thus causing serious injuries. These are problems that can be avoided when you use the right tools.

A safe workplace not only enhances the morale of workers but also prevents accidents from occurring. If your workers are injured when prying out manhole covers to access the ground channels, then you pay for the medical treatment cost and the work completion may be delayed. The insurance premiums may also increase because of the claims.

Similarly, when you prying out those covers, you also need to lift them manually using you hands. This is another thing that can cause sprain on muscles or the manholes cover could slip and fall on your feet. Eye and flesh injuries may occur due to detached pieces of metals that fly when you release the hammer and it hits the pry bar. The flying pieces of metals detaching from manholes covers and bars can cause eye injuries.

Other people around the area can also suffer injuries if something wrong happens. Since the safety of people working on manholes needs to be emphasized, it is important you provide tools that make it easy to open those covers. This is where the manholes cover lifters come in handy. They are designed to allow easy opening of covers without using strenuous forces.
