Abstract
PURPOSE: To simplify the structure of electric hoist and reduce its manufacturing costs, by providing a one-way coupling means between the braking member and turninf shaft of motor.
CONSTITUTION: In raising loal, button is closed whereby armature 12, turning shaft 13 of motor and a first bevel gear 13a are turned to the left as viewed from the side of commutator, a pair of a second and a third bevel gears 27, 24 are turned to the right, idle gear 45 and a forth and a fifth bevel gears 31, 42 are turned to the left, and a sixth bevel gear 43 and winding drum 32 are turned to the right. Winding drum 32 is wound up by the thrust acted to a pair of turning shafts 23, 23, since axial thrust is acted to the right to the second and the third bevel gears 27, 24, thereby urging braking member 37 to braking surface 36a via pressing member 40 but its braking force is relatively small. In lowering the load, on the other hand, braking member 37 is turned with shaft 13, since shaft 13 and braking member 37 are coupled together by means of one-way coupling means 38.
