Double head horizontal bolt wrench NLB-600 bolt wrench rail sleeper bolt mobile wrench

Description :

　　Double head bolt wrench for internal combustion bolt tightening machine NLB-600 type internal combustion engine mobile double head bolt wrench

　　Product Features:

　　1. The NLB-600 internal combustion engine bolt wrench adopts an oil immersed tooth embedded inclined friction clutch torque, greatly improving the lubrication conditions of the upper and lower clutches and reducing tooth wear to the smallest extent possible. It has the characteristics of stable torque, accurate torque indication positioning, and long service life of friction clutch. Solved many technical difficulties and defects in the practical application of tooth embedded inclined friction clutch.

　　2. The gearbox body is made of aluminum alloy casting, which not only further reduces the overall weight of the machine, but also realizes a fully enclosed internal oil lubrication method. On the one hand, it controls the machine noise to the minimum level, and on the other hand, it fully adapts to harsh working environments such as wind and sand.

　　3. The adjustment torque range is large, with a forward tightening adjustment range of 60-200N, m and a reverse loosening torque of 600N, m, and equipped with torque adjustment markings.

　　4. The machine is designed according to the theoretical parameters of ergonomics, making the operating mechanism more applicable and preventing excessive bending during operation.

　　5. The working sleeve of this machine not only has the advantage of automatic hat removal, but also can automatically eliminate the inclination and center distance errors of the rail sleeper bolts, as well as the ultra-high inclination errors of the line during curved line operation, and accurately fit the bolts and nuts.

　　6. When there is an over working condition on the road, that is, when the sleeve and bolt nut get stuck, it has a quick and simple function to separate the sleeve from the main engine, fully eliminating the safety hazards caused by sleeve sticking during line maintenance and repair under over working conditions.

　　7. The unique front and rear running wheel adjustment device can conveniently and quickly adjust the distance between the working sleeve and the bolt. Suitable for the maintenance and repair of rail sleeper bolts in straight and curved sections of track lines with various types of steel rails in China.
