Manhole cover opener
The invention discloses a manhole cover opener comprising a base, supports and an H-shaped crossbeam welded by channel steel. One end of the crossbeam is cut to a T-shaped structure. The base is provided with two vertical supports which are arranged at an interval, the T-shaped end of the crossbeam is inserted between the two supports and connected with the two supports through bolts. The crossbeam is perpendicular to the supports and pivots the bolts, the upper bottom face of the crossbeam is provided with a U-shaped handle, and the crossbeam has a vertical connecting hole which is 2/3 to 4/5 of the length of the crossbeam away from the connecting end. The invention is easy to operate, mechanical work almost replaces manual work in the past, the measurers' labor can be saved, the work efficiency can be raised, and the construction period of the outside work can be greatly shortened.
