The present application relates to a mobile counterweight mechanism of a hoisting machine, comprising a support portion, a drive portion and a counterweight which is articulated to said support portion by means of a first articulation portion, said drive portion connected between said support portion and the counterweight so that said counterweight turns over outwards about said first articulation portion relative to a center of rotation of said hoisting machine, so as to increase a distance between a center of gravity of said counterweight and a center of rotation of said hoisting machine. The present application also relates to a hoisting machine. The present application raises a movement distance of a mobile counterweight and improves the overall stability of a hoisting machine in a turnover manner.
