The invention relates to a movable type counter weight mechanism of a hoisting machine. The movable type counter weight mechanism comprises a supporting part, a driving part and a counter weight, wherein the counter weight is hinged with the supporting part by a first hinging part; and the driving part is connected between the supporting part and the counter weight so that the counter weight can be overturned outwards relative to a rotary center of the hoisting machine around the first hinging part, and furthermore, the distance from the gravity center of the counter weight to the rotary center of the hoisting machine is increased. The invention further relates to the hoisting machine. The movement distance of the movable counter weight is increased by an overturning manner and the whole stability of the hoisting machine is improved.
