| Abstract: | The erecting of the mast is an important principle and preparation for lifting the huge equipment by mast crane. This article is aimed at theoretical research about the speed of releasing the pulleyblock on the bottom when we erect the mast in rotating way. The result is discussed briefly according to engineering practice. |
