Common types
Rail Profile Weld Grinder
The rail profile weld grinder not only have the technical performances such as profiling accuracy and grinding efficiency been significantly improved, but also the intelligent control of grinding wheel feed has been achieved due to the development and application of the numerical control feed unit.It greatly simplifies the operation steps in construction, measurement, maintenance and other aspects, and avoids the problem of "excessive grinding" during construction.
Rail Tamper Machine
The rail tamper machine is driven by a Honda four-stroke gasoline engine and features large excitation force, high vibration frequency and stable hydraulic system. This machine features a compact structure and flexible operation, making it suitable for complex track sections and space-constrained areas. It can effectively enhance the compactness of the track bed and ensure the stability of the track's geometric state.
Bolt Impact Wrench
The internal combustion bolt impact wrench is powered by a gasoline engine. The output shaft is single-head and single-speed, with adjustable forward and reverse rotation. The output torque can be manually adjusted and precisely displayed.The whole bolt impact wrench is easy to operate, safe and reliable. It is convenient to get on and off the track. Moreover, it can be equipped with a lighting lamp to illuminate the sleeve head during night operations.
Abrasive Rail Cutting Machine
The internal combustion abrasive rail cutting machine is developed by Henan Qiangli Machinery Co., LTD. The rail cutting machine is suitable for cutting 43kg/m, 50kg/m, 60kg/m and 75kg/m type rails in railway maintenance and engineering departments. Especially in emergency rescue and track changing operations, the efficiency is remarkable. This machine is equipped with a Swedish K1270 gasoline engine and a specially designed rail fixture, which is convenient for cutting operations on various types of rails in China.
