However, the work required intermittent lifting and lowering within reachable heights, which had the disadvantage of being extremely labor-intensive. In addition, it is difficult for one person to lift and lower the lifting device and apply lubricating oil.
It usually requires two workers, which has the disadvantage of high labor costs. Moreover, the worker must apply the lubricating oil near the mast 1 of the lifting device main body 3 while extending his arm, which increases the fatigue of the worker. The disadvantage was that the work had to be done at heights, which was dangerous.
