1965年11～12月在北京举办的法国工业展览会上,展出挖掘机的有 Richier 和 Yumpo 两个公司。Richier 公司的 Oleomat 厂共生产15种型号的挖掘机,其中液压的7种,机械的8种。液压挖掘机是1955年开始生产的,到目前为止,已生产的有斗容量0.25～1.9米~3;现正在制造中的 H44C 型,其斗容量为2.8米~3,功率380马力。机械式挖掘机的斗容量0.23～2.7米~3,功率25～330马力。Richier 公司在这次展览会上共展出了3台挖掘机。一台是 H11P 型液压式挖掘机(如图1)。其行走机构是机械传动的;发动机功率为52马力,带反铲时工作重量10300公斤,可回转360°,有4档前进速度(3～18公里/时)和1档后退速度,双轴驱动,前轮
During the French industrial exhibition held in Beijing from November to December 1965, two excavators, Richier and Yumpo, were exhibited. Richier’s Oleomat plant produces a total of 15 models of excavators, of which 7 are hydraulic and 8 are mechanical. The hydraulic excavator started production in 1955. So far, it has produced a bucket capacity of 0.25 to 1.9 meters to 3; the H44C model, which is currently under construction, has a bucket capacity of 2.8 meters to 3 and a power of 380 horsepower. The mechanical excavator has a bucket capacity of 0.23 to 2.7 m~3 and a power of 25 to 330 hp. Richier exhibited three excavators at this exhibition. One is the H11P hydraulic excavator (Figure 1). Its running mechanism is mechanically driven; the engine power is 52 horsepower, the working weight is 10300 kilograms with a backhoe, can rotate 360 degrees, there is a 4 speed forward speed (3 ~ 18 km/h) and 1st gear retreat speed, double shaft drive Front wheel
