NLB-600 intermal combustion stud wrench

Applying Scope

NLB-600 type internal combustion stud wrench is suitable for loosening and tightening of sleeper bolts laid by various types of rail on existing rail lines in China.

Features

· NLB-600 type internal combustion stud wrench adopts oil-immersed large-area trapezoidal convex friction clutch, which greatly improves the lubrication conditions of the upper and lower clutches and minimizes the wear of the tooth surface. It has the characteristics of stable torque, accurate positioning of torque indication and long service life of clutch. It solves many technical difficulties and defects of friction clutch in practical application.

· The gearbox box adopts the die-cast aluminum alloy manufacturing process, which not only further reduces the weight of the machine, but also realizes the fully enclosed oil-immersed lubrication method, on the one hand, the noise of the machine is controlled to a minimum, and on the other hand, it ADAPTS to the operation in the harsh working environment such as wind and sand.

· Specially designed oil level observation hole, can easily fill lubricating oil and can know the use of lubricating oil in time.

· The adjustment torque range is large, the adjustment range of forward tightening working torque is 80-150N.m, the maximum can reach 350N.m, and is equipped with torque adjustment marking instructions. The maximum reverse loosening torque can reach 850 N.m.

· The machine according to the man-machine system design principle, so that the control mechanism is more practical, reduce the fatigue strength of workers.

· The working sleeve of this machine has the feature of automatic hat removal, which can automatically eliminate the center moment and inclination error of the sleeper nut and the ultra-high inclination error of the line during the curve line operation, and accurately insert the bolt and nut.

· In the case of excessive working conditions on the road, that is, when the sleeve and bolts and nuts are blocked, it has the function of quickly separating the sleeve from the main engine, eliminating the most dangerous safety risks caused by the sleeve card in emergency situations during line maintenance and repair operations.

· The front and rear running wheel adjustment device, can easily and quickly adjust the working sleeve and bolt aistance. It issuitable for the maintenance and repair of the sleeper bolt of the track line laid by various types of rail in our country.
