Abstract

See full text

A manhole cover moving assembly and method for moving a manhole cover works to lift, lower, rotate, extend, retract, and laterally displace a manhole cover over a short distance and in difficult to access areas. The moving assembly detachably attaches a hitch to a mobile mount for portability. The moving assembly provides a mast and a shaft that operate at adjustable relative to create mechanical advantages while moving the manhole cover. A telescoping support arm adjusts the angle of the shaft relative to the mast. The shaft carries a pulley apparatus and a cable that suspends the manhole cover. The mast rotates about a hitch. The shaft pivots about the mast. The shaft also extends and retracts. Further, as the angle of the shaft is changed through manipulation of the telescoping support arm, the mechanical advantage is increased for facilitating movement of the manhole cover.
