| Abstract: | Hydraulic synchronizing continuous slippage technique which integrates mechanical,electrical and hydraulic control is introduced in this paper on the basis of the practical requirements of some construction projects,and the core of this technique that the stability of the load transfer is illustrated in detail.Three speed control strategies,namely excessive speed to turn over the load,lower speed to turn over the load,same speed to turn over the load are presented to accomplish the smoothness and stability in the process of slippage.An optimization of the speed control strategy that the same speed turns over the load is deduced from the modeling analysis and its validity and maneuverability are tested by practical application,which provides evidence for similar engineering in theory and practice. |
