The invention discloses a balance hoisting machine. The balance hoisting machine comprises a rotary upright column, a balance arm, a balance arm support and a power mechanism, wherein the balance arm is a three-connecting-rod structure formed by the sequential hinged connection of a connecting rod I, a connecting rod II and a connecting rod III; one end of the connecting rod I of the balance arm is fixedly connected with a guide wheel shaft II of a vertical guide wheel, so that the upper end of the connecting rod I moves up and down along a vertical slideway by virtue of the vertical guide wheel; a chain wheel I is fixedly arranged at one end hinged to the connecting rod II, of the connecting rod I; a chain wheel II is fixedly arranged at one end hinged to the connecting rod II, of the connecting rod III; the chain wheel I and the chain wheel II are positioned in the same vertical plane; the connecting rod I and the connecting rod III are positioned in the same vertical plane and are parallel to each other; the chain wheel I and the chain wheel II are driven by a chain. The balance hoisting machine disclosed by the invention can hoist small weights in all directions in space, so that the labor strength for carrying weights is effectively reduced, the working efficiency is improved, and the safety is improved; the balance hoisting machine is simple in construction, compact in structure, simple and convenient to operate, and high in practicability.
