本标准代替GB/T 7586-1996《液压挖掘机试验方法》和GB/T 10675-1989《液压挖掘机 可靠性试验方法》。 本标准规定液压挖掘机的性能试验方法、工业性试验方法和可靠性特征量的计算方法。
本标准适用于整机工作质量不大于200t的液压挖掘机,其他规格的挖掘机可参照使用。
本标准与GB/T 7586-1996和GB/T 10675-1989相比,主要变化如下:
——将GB/T 7586-1996《液压挖掘机试验方法》和GB/T 10675-1989《液压挖掘机 可靠性试验方法》。
两项标准合并为GB/T 7586-2008《液压挖掘机 试验方法》;
——振动试验的结果分析方法直接引用GB/T 4970-1996的附录A;
——测量准确度的要求、质量和重心的测定、司机的操纵装置的测定、司机视野的测定、行驶速度的测定、轮胎式挖掘机转向尺寸的测定、制动性能试验等项目的试验方法直接引用相关标准的规定;
——将土壤等级与GB/T 9139-2008《液压挖掘机 技术条件》统一,按土壤密度表示;
——将GB/T 7586-1996中的引用标准JB 3774.2改为GB/T 16710.2~16710.5;
——增加了起重量试验,电气设备及系统的试验,监视污染物的测定,照明、信号和标志灯以及反射器的试验,前进和倒退音响报警响的试验,监视镜和后视镜的试验,司机防护装置和小型挖掘机倾翻保护结构(TOPS)的试验,司机室环境的试验,液压系统油液固体颗粒污染度检查等项目的试验方法直接引用相关标准的规定;
——增加了空运转试验;
——删除了实际挖掘试验;
——将工业性试验时间改为:小型液压挖掘机不少于400h,大于6t的液压挖掘机不少于800h;
——删除了工业性试验中的解体检查。
