The invention discloses a special machine for mounting and dismounting an inward-open manhole cover. A base end moves forwards and backwards through rolling wheels; an mounting rack moves up and downat the upper end of a base through a lifting platform; a working rod is slidably installed on the mounting rack; the working rod moves forwards and backwards by a driving hydraulic cylinder; a fixed plate is rotationally installed at the end of the working rod; and the fixed plate swings up and down. The invention relates to mounting and dismounting equipment, particularly relates to a special machine for mounting and dismounting an inward-open manhole cover, and belongs to the technical field of installation of manhole covers. The special machine disclosed by the invention can move conveniently; by arranging the lifting platform and the driving hydraulic cylinder, the working rod equipped with the manhole cover is driven to move up, down, forwards and backwards so that movement of the manhole cover is realized, the manhole cover can be conveniently installed at the inner end of a manhole, the labor intensity can be effectively alleviated, and the work efficiency is improved.
