ROC812H型-是一人操作的用于孔径在64至127毫米(2 1/2至5英寸)范围内的阶梯式凿岩钻车。该钻车不。仅生产率高,钎杆经济效果好,而且燃料消耗也少。 ROC812H型钻车与长达3.6米(12英尺)的T38(1 1/2英寸)和T45(1 3/4英寸)两种接长钎杆配套使用。钎杆操纵机械化使钻车在整个工作循环中能获得较高的工作速度。凿岩经济效果总的凿岩济经效果的好坏取决于所用设备的几个重要的特点,其中一些关键因素是凿速高、钎杆好、燃料省和维修费低。
Model ROC812H - is a one-man step-up rock drilling rig for apertures ranging from 64 to 127 mm (2 1/2 to 5 inches). The rig is not. Only high productivity, drill rod economic effect, but also less fuel consumption. The ROC812H drill rigs are used with two long shank rods of up to 3.6 m (12 ft) T38 (1 1/2 in.) And T45 (1 3/4 in.). Drill rod mechanization of the drill so that the entire work cycle can get a higher working speed. Economic Effects of Drilling The overall effectiveness of a rock drilling business depends on several important characteristics of the equipment used. Some of the key factors are high chipping speed, good drill shank, low fuel costs and low maintenance costs.
