维克多(Victor)产品开发公司主要是为英国煤炭工业制造和提供凿岩设备。它的许多产品在采矿工业和其它易燃易爆工业中得到应用。新研制的Trojan液压旋转冲击式凿岩机适于钻凿锚杆孔、炮孔和沼气排放孔。Trojan凿岩机特别适用于钻凿硬岩,能满足长期以来对钻凿浅孔(孔深2.5米以内)的手持、支腿式液压旋转冲击式凿岩机的需求,并试图用它来取代风动凿岩机。液压凿岩机与风动凿岩机比较具有一些重要的优点,即噪声低和振动小。具有较好的灵活件和经
Victor Product Development primarily manufactures and supplies rock drilling equipment to the British coal industry. Many of its products are used in the mining industry and other flammable and explosive industries. The newly developed Trojan hydraulic rotary percussion rock drill is suitable for drilling anchor holes, boreholes and biogas vents. Trojan rock drills are particularly well suited for hard rock drilling and have long met the need for hand-held, leg-type, hydraulic rotary rock jack drilling shallow holes (within 2.5 meters) and attempted to replace them with pneumatic rock drills. Hydraulic rock drills have several important advantages over pneumatic rock drills: low noise and low vibration. With better flexibility and experience
