The positioning of back skating wheel 144 is set as optimizing such a ability, i.e., as vertical as possible below suspension rod pulley when scraper bowl is emptied
Scraper bowl operation is horizontal position by ground.When scraper bowl is full of and therefore becomes heavier, prevent from increasing heeling moment and toppling over rope
Tension needed for rope also increases.If it is assumed that tension can integrally be transferred to and topple over rope 146 to keep scraper bowl water in drawstring 122
Flat, then it is observed that ground is, due to toppling over the increase of required tension in rope, thus scraper bowl must be from suspension rod pulley vertical lower
Site is increasingly far mobile.Further, since toppling over pulley 144 is attached to ropes 114, thus topples in rope 146 and open
