Introduction

A railway excavator, also known as a railroad excavator or hi-rail excavator, is a specialized construction machine
designed to work efficiently on railway tracks. Unlike standard crawler or wheel excavators, a railway excavator is equipped
with a hi-rail system—a set of rail wheels that allow the machine to travel safely and steadily on rails.
Railway excavators are widely used for track maintenance, rail construction, ballast handling, sleeper replacement, ditch cleaning,
and emergency repair tasks. Thanks to their versatility, they can switch quickly between road mode and rail mode, making them
essential equipment for modern railway maintenance teams.

Installing a Hi-Rail system on a railroad excavator dramatically enhances its mobility, safety, versatility, and cost-efficiency. For any contractor involved in railway maintenance, construction, or emergency repair, the Hi-Rail system is no longer an optional accessory—it is an essential tool that improves productivity and guarantees safety.
By installing different tools like the sleeper changer, ballast tamper, rail clamp, ballast sweeper, and ballast plough, railway contractors can complete projects faster, safer, and at a lower operational cost.
