Why do railway excavators have to install Hi Rail System

In today's railway construction and maintenance field, equipment safety, efficiency, and mobility have become core competitiveness. With the continuous expansion and upgrading of the global railway network, construction units and contractors urgently need a multifunctional equipment that can operate on ordinary ground and safely travel on steel rails - this is the fundamental reason why more and more companies choose to install Hi Rail Systems (railway guided walking systems) for excavators.

So, why do railway excavators have to install Hi Rail System?

What is Hi Rail System

Hi-Rail System， Also known as railway guide wheel system/railway walking system, it is a set of hydraulic retractable rail guide wheels installed in the front and rear of railroad excavators.

When it is necessary to enter the track for operation, the guide wheel is lowered to allow the excavator to travel along the track;

When constructing on ordinary ground, the guide wheels are retracted, and the excavator still maintains its original walking mode.

It essentially enables excavators to have amphibious walking capabilities: highway+railway

Improving Mobility: Allowing Excavators to 'Freely Shuttle' on Railways

Excavators without Hi Rail systems must:

*Transport by trailer to the designated route

*When moving, manual command and scheduling are required and time-consuming

*Very inflexible.

After installing the Hi Rail system, the railroad excavator can:

*Self propelled up and down track

*Quickly move along the track to different construction sites

*Significantly improve the efficiency of line construction

For engineering teams maintaining long-distance lines, this mobility advantage is very obvious

Adapting to the "skylight period" operation

Most railway maintenance projects must be completed during the brief window period at night.

Time is precious, and it is necessary to evacuate the track on time and not occupy the road.

The advantages of Hi Rail system are more prominent in skylight operations:

*Quickly enter the track without delaying construction time

*Quickly switch between different homework points

*Emergency situations can quickly evacuate the track

*Adapt to high-intensity and fast-paced nighttime construction requirements

Excavators without Hi Rail systems often cannot meet the high efficiency requirements during the peak period.

Improving the safety of railway operations

The railway environment has very high requirements on equipment safety, and Hi-Rail system can significantly reduce risks.

Maintain the stability of the equipment on the track

The guide wheel structure ensures that the railroad excavator runs stably without derailment or drift.

Avoid damaging rails and fasteners

Excavator crawler or rubber tire directly pressing on the track will cause damage, and the guide wheel can reasonably distribute the pressure to protect the track structure.

Provide additional braking and locking functions

Many Hi-Rail systems are equipped with hydraulic brakes that allow the excavator to park safely even on ramps.

Controllability of lifting operation

The track guide walking mode makes it easier to control and locate the railroad excavator in the construction area of narrow line.

High-Rail system is an intrinsically safe device with high potential safety hazards in railway construction.

Expand the railway operation capacity of excavator

With Hi-Rail, the excavator can not only move, but also complete more high-value operations:

*Replace the sleeper

*Tamping the ballast

*Rail clamp and rail threader

*Ballast removing

*Repair of side ditch and slope

*Vegetation Removal, Tree Pruning

*Joint emergency repair of road/railway

One excavator with Hi-Rail can almost replace several special railway equipment.

Whether it is railway maintenance, line construction, emergency rescue or routine maintenance, Hi-Rail system provides the excavator with higher mobility, safety and operation capacity. For any contractor engaged in railway engineering, the Hi-Rail system is not only an accessory, but also an essential productivity tool, but also an investment directly improving efficiency and competitiveness.

The installation of Hi-Rail system is to make your excavator really become the railway professional equipment and take the advantage in the railway engineering market in the future.
