一机部部颁标准JB××××-78液压单斗挖掘机型式与基本参数,JB××××-78液压单斗挖掘机技术条件,JB××××-78液压单斗挖掘机型式试验,和JB××××-78机械式单斗挖掘机型式与基本参数,技术条件,将颁布施行。对液压挖掘机来说,这套标准是我国第一批较完整的产品标准。这几个标准一起构成了我国今后单斗挖掘机按系列发展品种,全面实现产品系列化、通用化、标准化的依据。也为安排和组织专业化协作生产创造了基本条件。今后,无论
The Ministry of Machine-Building Division issued standard JB××××-78 hydraulic excavator type and basic parameters, JB××××-78 hydraulic excavator technical conditions, JB××××-78 hydraulic single bucket excavation Type test, and JB×××-78 mechanical single bucket excavator type and basic parameters, technical conditions, will be promulgated. For hydraulic excavators, this set of standards is China’s first batch of relatively complete product standards. Together, these standards form the basis for the development of single bucket excavators in China in the future and the basis for serialization, generalization, and standardization of products. It also creates the basic conditions for arranging and organizing specialized collaborative production. In the future, no matter
