ABSTRACT:
A hoisting and pulling device has a frame body (13) made by integrally forming a speed reducer side frame (13b) on an outer peripheral edge surface of the frame body, a drive side frame (13a) on the outer peripheral edge surface of the frame body, and a frame connection section (16) on the outer periphery of a load sheave receiving section. The speed reducer side frame (13b) rotatably supports a speed reducer gear (3) and has a speed reducer side cover installation section (15b). The drive side frame (13a) has a drive side cover installation section (15a). The frame connection section (16) has guide grooves (22a, 22b) for guiding a chain (11) run around the load shave. Both frames (13a, 13b) have hook installation holes (24) for rotatably supporting a hook for suspending a body frame on the load side. The structure above reduces the number of parts and assembling man-hour and makes the structure simpler, reducing the size and costs.
