NLB-500 Internal Combustion Bolt Wrench for Railway Nut Fastening

• Purpose: Used for loosening and tightening the bolts and nuts of railway track sleepers.

• Power: Equipped with a two-stroke gasoline engine power source, with a power of 1.47KW.

• Main technical parameters: Torque 550N.M, no-load speed 2700rpm, loaded speed 7120rpm, fuel tank capacity 1L, fuel mixture ratio 25:1, overall weight about 18KG.

• Performance characteristics: Novel design, compact structure, small size, light weight, strong mobility, portable and easy to carry on and off the track, two-stage shock absorption on the handle, good balance, can stand vertically, and the operation switch is easily accessible.

• Applicable scenarios: Particularly suitable for regional track maintenance operations in areas such as switches, tunnels, bridges, and culverts where large and medium-sized maintenance machinery cannot operate. It can also be used in remote areas without power facilities, air compressors, or generators, such as rainforests, mountains, or deserts.

• Structure and working principle: Composed of a small gasoline engine, planetary gear transmission, rotation direction converter, impact booster, output shaft clutch, socket head, and operation handle. During operation, the engine's rotational torque is transmitted through the clutch, universal joint, and bevel gear reversing and reduction mechanism to achieve direction change and speed reduction, then passed to the impact booster mechanism, and finally used to loosen and tighten bolts and nuts via the socket.
