In accordance with the present invention, disclosed is a manual lifting system with a high torque transmission planetary reducer, comprising: a rotation module (110) into which a bit holder of an electric drill (10) is introduced; a planetary gear module (120) composed of a sun gear (121), a planetary gear (122), a carrier (123), a carrier pin (124), a primary ring gear (125) that engages with one side of the planetary gear (122) in external contact, a secondary ring gear (126) that engages with the other side of the planetary gear (122) in external contact, and a bearing housing (127); a cylinder module (130) composed of a screw (132) into which the secondary ring gear (126) and a rotating shaft (131) are inserted and coupled, a screw pipe (133) that guides the lifting and lowering of the screw (132), a screw nut (134) that engages with the screw (132) in external contact, and a pipe housing (135), wherein the pipe housing (135) slides up and down based on the screw nut (134) by the rotation of the screw (132); a clamp module (140) composed of a clamp (141) fixed to the pipe housing (135) and a dobby fork (142) coupled to the clamp (141); and a caster (150) composed of and a footrest hinge (151) that supports the lower end of the screw pipe (133) and a pair of bases (152) each extending to both ends of the footrest hinge (151). Therefore, a high-load object mounted on the dobby fork (142) can be lifted by manually rotating a rotary port (111) to decelerate through the planetary gear module (120) and lift and slide the clamp module (140).
