现有轮式挖掘机行驶速度一般只有２０～３６ｋｍ／ｈ，作为开路、抢修先锋的轮胎式液压挖掘机，必须要有较高的行驶速度和较好的加速性能。贵州詹阳机械工业有限公司吸收国内外先进技术，自行开发研制了行驶速度达到５０ｋｍ／ｈ的ＪＹＬ２００Ｇ型轮胎式液压挖掘机，填补了国
Existing wheel excavators traveling speed is generally only 20 ~ 36km / h, as a pioneer, repair pioneer tire hydraulic excavator, you must have a higher speed and better acceleration. Guizhou Zhan Yang Machinery Industry Co., Ltd. to absorb advanced technology at home and abroad, developed their own speed of 50km / h JYL200G-type hydraulic excavator to fill the country
