If you want to access inspection chambers and manholes, you have to remove the covers that are installed on the surfaces. These covers are aimed at protecting the channels from things like debris and water, and preventing people from falling into the holes. Removing those covers can be a problem for the maintenance personnel if they do not have the right tools to lift them. This is why it recommended that the maintenance workers use modern innovative manhole cover lifter tools.
Using methods such as thumping hammers and crowbars to ease the grip of the frames and covers does work but it presents many risks. It is not only time consuming but also unsafe to use. When the crowbars are thumped using sledge hammers, accidents can occur.
The hammer may miss the crowbar and hit the feet or toes. Additionally, lifting hammers can cause muscle and joint sprains. There is a lot of lifting activity involved when you use traditional methods to unseat and free up covers from manholes. The manholes may not have been opened for quite a while and this means that the frame and cover could be difficult to release.
The lifters are designed to allow maintenance personnel to be able to access the inspection chambers and manholes easily. With such lifters, they can help workers unseat and open covers easily without using a lot of force. This not only saves time but also reduces incidents of accident and injuries from occurring.
Traffic passing over, whether foot or vehicle, also exerts more pressure and pushes the lid further into the frame. The gap that is between the covers and frames may fill with debris and dirt making it even difficult to open those covers. Besides, the effect of corrosion may create more trouble because it makes such covers and frames to hold tight together.
The modern types of lifters are however more advanced and they are designed to allow the users apply little force. It requires no physical efforts of lifting and actually, what is needed is a downward action, which allows the mechanical advantage that is inherent in the designs to reduce greatly in relation to the weight of such covers. The task is performed as easily as pushing down the handles to allow the covers to be lifted.
A user does not have to pull anything up. The best way in which maintenance workers can unseat jammed covers is to apply some force nearest or closest to the cover edge. When you use the modern covers lifters, you find that they are easy to move them around. The speed of deployment ensures that you achieve your results fast.
Since the impact on surfaces due to thumping could make parts of the metal to detach and fly in air, the workers risk injuring their eyes and puncturing the skin. Those working around the areas may also be put at risks by the flying pieces of metal. The time take to do the task becomes long and workers may not be able to achieve meaningful results in inspecting or working on the channels because the covers cannot open fast.
