The invention discloses a novel easily-maintainable winch. The novel easily-maintainable winch comprises an electromotor and a triangular belt, and is characterized by further comprising a dustproof cover, a cooling fan, a waterproof cover, a temperature sensing probe, a controller, a buzzer, a magnetic rotor and a storage battery, wherein the exterior of the electromotor is covered by the dustproof cover; the cooling fan is mounted on the dustproof cover. According to the novel easily-maintainable winch, the additionally-arranged dustproof cover is capable of effectively preventing the dust from entering the electromotor; the cooling fan is capable of accelerating the cooling of the electromotor when the electromotor works; the waterproof cover is capable of preventing a winding drum from being excessively humid and preventing steel wires from ageing; the temperature sensing probe is capable of monitoring the temperature in the electromotor at all the moments; when the temperature in the electromotor is excessively high, the temperature sensing probe is capable of sending signals to the controller, triggering the buzzer to buzz and give an alarm and preventing the electromotor from continuously working under the high-temperature condition; when the winch works, a main shaft rotates and drives the magnetic rotor to rotate so as to generate induced electromotive force and electric energy and store the electric energy in the storage battery; the electric quantity stored in the storage battery can be used as a standby power supply when the power is cut off; the usability of the novel easily-maintainable winch is improved.
