A labor-saving device for detection of no-load hand hoist motion, including a base, a stand pole, and a controller, a first cantilever beam, a second cantilever beam, a third cantilever beam, and a fourth cantilever beam being sequentially disposed in single vertical plane from top to bottom of the stand pole. Specifically, the electric hoist being disposed below the first cantilever beam; a pair of first guide unit being respectively disposed at two opposite laterals of the second cantilever beam; a driving unit including a motor, a stand plate, and an actuator being coaxially disposed in series from internal to external, being disposed above the third cantilever beam; and a pair of second guide unit are respectively disposed at two opposite laterals of the fourth cantilever beam.
