Problems solved by technology

[0002] At present, the manhole cover is installed on the top of the tank body of the vehicle. It is a passage for people to enter and exit the tank, and an observation port for checking the goods and the natural conditions inside the tank. Generally, it is a cast iron cover plate. The cast iron cover plate itself is relatively heavy. There is no protective measure for the staff when opening and closing. It is dangerous to use and prone to accidents. In order to solve the above problems, we propose a simple safety manhole cover with handrail function
