Abstract
A hoisting and pulling device has a frame body () made by integrally forming a speed reducer side frame () on an outer peripheral edge surface of the frame body, a drive side frame () on the outer peripheral edge surface of the frame body, and a frame connection section () on the outer periphery of a load sheave receiving section. The speed reducer side frame () rotatably supports a speed reducer gear () and has a speed reducer side cover installation section (). The drive side frame () has a drive side cover installation section (). The frame connection section () has guide grooves () for guiding a chain () run around the load shave. Both frames () have hook installation holes () 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.
