Portable Internal Combustion Rail Bolt Wrench
The NLB-1800 Rail bolt wrench is novel in design, compact in structure, small in volume, light in weight, strong in maneuverability, two-stage shock absorption of handle, portable in hand, convenient in getting on and off the track, especially suitable for the regional maintenance operation of track bed where turnout, tunnel, bridge and culvert and other large and medium-sized railway maintenance machinery cannot work.
- Product Introduction
It is a kind of high performance tool with two-stroke gasoline engine power source. It is the lightest one of the impact wrenches. It can produce a large torque with a small engine. Its weight is only 20kg. It has good balance and can stand vertically. The operation switch is located within the range of the operator's easy access, so it is more convenient to operate. Because of its own power source of gasoline engine, it can be easily carried to any construction site by single person, such as: rainforest, mountain or desert, and remote areas without power facilities or air compressor and generator. It can be used for M32 bolts at most, and it is most suitable for the fastening of sleeper bolts and other bolts.
