The invention belongs to the technical field of exercise equipment, and particularly relates to steel wire type exercise equipment based on heavy block gravity. The steel wire type exercise equipmentcomprises a handle, a guide shell, a supporting plate, a winding wheel, a seat and a heavy block mechanism. When people want to take exercises, they sit on the seat and pull the handle, and the handlecan exert downward tensile force on the winding wheel through a steel wire fixed on the handle; meanwhile, the heavy block mechanism can also exert downward tensile force on the winding wheel; at themoment, the winding wheel can move down along a limiting trigger groove; when the winding wheel moves to the bottommost end of the limiting trigger groove, the winding wheel can be made to rotate through the tensile force exerted by people on the steel wire, the winding wheel rotates to make the steel wire wound on the winding wheel rotate, and the steel wire wound on the winding wheel rotates todrive a hook shell and an installation shell in the heavy block mechanism to move upward, so people can make the heavy block mechanism move up and down by controlling the handle, and people can takeexercises.
