Energy-Saving Research on Hydraulic System of Lifting Mechanism of Truck Crane

2016 International Conference on Intelligent Transportation, Big Data & Smart City (ICITBS), 2016
At present, China's truck crane is often out of the crane and the crane operator safety considerations, was given a larger design safety factor in the load circuit into a larger load, resulting in a hoisting mechanism hydraulic system is very Large energy loss.

Dynamic behavior of the lifting crane mechanism

Mechanism and Machine Theory, 1995
Abstract In the present paper the motion of a lifting mechanism of crane is considered. The unloading procedure is analyzed when the mass of the mechanism is varying. Due to the mass variation a reactive force appears. The influence of the reactive force on the motion of the system is investigated.
