Abstract

PURPOSE: To provide a hoist outer frame made of steel plate, which is designed such that it is not required to apply facing to one side plate of the outer frame located on the side of motor, but facing is applied only to the other side plate located on the opposite side, whereby it is enabled to make the outer frame light and to reduce the number of jobs in manufacturing the same.
CONSTITUTION: Hoist outer frame of this invention is designed such that it is not required to apply facing to side plate 18 located on the side of motor 7 that does not require so strict dimensional tolerances, but facing (16) is applied to the other side plate 3A located on the opposite side for fixing reduction gear unit 5. Side plate 18 of outer frame 4' is placed in plane 20 on jig 21 of cutting means. In maching the same, coupling surface 17 of side plate 3A is faced (at 16) at first, and then coupling surface 14 of the other side plate 18 is faced while keeping the outer frame at the same position. With such an arrangement, it is not required to turn the position of outer frame 4' in machining the same and it is enabled to complete machining of two side plates 3A and 18 at one position, so that number of jobs in manufacturing the outer frame 4' can be reduced considerably.
