In recent years,with the increase of the infrastructure,the demand for crawler cranes gradually increased.At the same time,a large crawler crane stability problems stand out.Past crawler crane stability studies,method by ADAMS/view the model simulation,ensure that the target point by point when the position of the target from the ground to determine whether began overturning Crawler Cranes Crawler overturning online,its drawback is that,according to the security GBT3811-2008 crane design specification requirements for the total load on the side of the chassis or the minimum load bearing ends of overturning line of not less than 15% of its pressure.In accordance with past judgment method,the target point from the ground track supportive zero has occurred overturning.The object of study for the SD750 crawler material handling machine,due to the nature of work as the same crawler crane way,the analysis of the stability studies is in accordance with safety standards GBT3811-2008 crane design specifications when conducting research.In this paper,Crawler material handling machine stability studies to solve the above problem,a new calculation scheme.At the bottom side of the track line installation overturning spring as force sensors,on the other side of the track line installed hinged overturning deputy.To determine the stability of SD750 crawler material handling machine is by the force of the spring.(1)Analysis of the basic stability of the 95-point SD750 crawler material handling machine in which the end of the forearm to simulate and get the ultimate load under which each point.(2)The maximum allowable non-operating wind load analysis of the wind in the material handling machine SD750 crawler biggest wind simulation,the SD750 crawler material handling machines in the wind can withstand extreme wind scale.(3)Backward analysis of the stability of the material handling machine in the SD750 crawler on the slopes under 14 wind simulations,simulation data obtained meet the requirements.(4)Dynamic stability analysis,the SD750 crawler material handling machine under dynamic simulation to obtain envelope Figure forearms and turntable movement under the bottom track and two force chart.
