NJLB-600-type internal combustion stud wrench move NJLB-600-type internal combustion stud wrench move NJLB-600-type internal combustion stud wrench moving all in-billion mining machinery, professional quality, strong technology, advanced technology, stud wrench preferred brand is Yian mining machinery hotline 1, NJLB-600-type internal combustion stud wrench move using oil immersion jaw bevel friction clutch torque greatly sent on the clutch lubrication conditions, so that the tooth surfaces to reduce wear minimum. With a stable torque, torque indication positioning accuracy, long service life of the friction clutch. Solve the jaw bevel friction clutch many technical difficulties and deficiencies in actual use. 2, the transmission housing made of aluminum alloy casting, not only further reduce the overall weight and achieve lubrication oil fill within a fully enclosed, while the machine with minimal noise control in hand, and fully adapt to the harsh sandstorms operating under the working environment. 3, adjust the torque range, tighten the adjustment range of the forward 60-200N.m, reverse unscrewing torque 600 Nm, and is equipped with a torque adjustment engraved lines indicate. 4, ergonomically designed machine theory parameters required to make more applicable control mechanism, to prevent operation when caused by excessive bending over. 5, the machine automatically hat work not only has the advantages of the sleeve, but also on the incline sleeper bolts, center distance errors and the line in the graph line of ultra-high job tilt error, can eliminate automatic, accurate set into the nuts and bolts. 6, in the emergence of ultra trail working condition, that occurs when the sleeve nut and bolt happen card cap, with a rapid and easy separation of the sleeve and the host function, fully exempt in line maintenance, repair super working condition, because the sleeve card cap and cause safety problems. 7, unique front and rear walking wheel adjustment device, to quickly and easily adjust the spacing sleeve and bolts work. Suitable for various types of existing rail track laying straight lines, curved lines lots of maintenance and repair work sleeper bolt. Technical parameters: Gasoline Power: 6.7KW maximum torque Loosen: ≧ 600N.m sleeve center distance: 216mm Dimensions: 1060 × 530 × 750mm tightening torque adjustment range: 60-200N.m efficiency: 2 / sec Host Quality: 84KN
