The invention discloses a hoisting machinery. The hoisting machinery comprises a rotary table, a hoisting arm, a counterweight device, a secondary winching device, a super hoisting rope and a pulley device, wherein the hoisting arm, the counterweight device and the secondary winching device are respectively arranged on the rotary table; the pulley device is arranged on the counterweight device; the first end of the super hoisting rope is connected to the secondary winching device; the second end of the super hoisting rope bypasses the pulley device and is subsequently connected to the hoisting arm. Through the hoisting machinery, the counterweight device essential to a crane is used as a super hoisting bracket, so that a novel super hoisting structure is formed; no extra arrangement is increased; the structure is simple; the cost is relatively low; the hoisting machinery is applied to medium-small-tonnage telescopic cranes; the applicability of the hoisting machinery is improved.
