The Simulation Analysis of the Efficiency about Truck Crane Lifting Load Sensing Hydraulic Loop

Abstract

In this paper, the energy consumption of the truck crane lifting load sensing (LS) hydraulic loop is analyzed. AMESim is applied to model it, based on the design of a 70t truck crane lifting loop. And then the efficiency of it is simulated, comparing with the traditional truck crane lifting hydraulic loop. The simulation results clarify that the efficiency of the LS lifting hydraulic loop is obviously improved compared with the efficiency of the traditional one. Its efficiency has nothing to do with the load speed and is only related with the load. The results are useful to the design of large-tonnage truck crane lifting hydraulic loop.
