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.

Fundamental analysis and optimization (minimization) of dynamic loads in elastic elements of cranes load lifting mechanisms. Part I

Mechanics And Mathematical Methods
The fundamental analysis and optimization (minimization) of dynamic loads in elastic elements (ropes) of load lifting mechanisms of cranes used in urban development is carried out. The basis of the analysis and methodology of optimization of motion modes of the mentioned mechanisms is the approach implemented in the classical calculus of variations ...
