In addition , in case where a station down the chain to bear the weight causes beyond the chain broke , so since , in addition to three inverted chain will withstand the heavy weight of 40 tons , and down the chain or damage caused by the accident. Each chain bearing the correct way to pour all of 40 tons , so that once a station down the chain fails it will not affect the overall lifting work .
