The present invention relates to a super capacitance assembly energy storage type electric motor speed regulation tractor hoist. The tractor hoist consists of a three-phase alternating-current supply air switch, a charge power supply module, a capacitance assembly energy accumulator, a DC speed regulation module, a control panel, a main electric motor, a clutch, a gear shifting box, a power drive system, a winch clutch, a winch, an auxiliary brake clutch, an exceeding type clutch, an auxiliary brake DC motor, a charger, an energy accumulator, a bottom car system, a hydraulic system and a derrick system. The input and output ends of the three-phase alternating-current supply air switch are connected with an external power supply and the charge power supply module respectively; the charge power supply module, the capacitance assembly energy accumulator, the DC speed regulation module and the main electric motor are connected sequentially; the main electric motor is connected with the winch through the clutch, the gear shifting box and the power drive system in order; and an auxiliary brake system consisting of the auxiliary brake clutch, the exceeding type clutch and the auxiliary brake DC motor is arranged on the other end of the winch in order. The tractor hoist which has a reasonable design and reliable work can save energy, reduce energy consumption, and avoid damages on an electric network caused by a pulse power supply due to discontinuous power utilization.
