A hydraulic system energy analysis method for energy-saving design of crane lifting mechanism

Journal of Physics: Conference Series
Abstract During the lifting process of cranes, the lifting mechanism usually experiences significant energy loss, which is detrimental to the lifespan of the lifting mechanism. Therefore, it is particularly necessary to study energy-saving methods for the lifting mechanism of cranes.
