Preventive Maintenance

What We Do

Structured maintenance programmes aligned with operational schedules. Includes inspections and condition monitoring.

What You Receive

Documented maintenance programme with visit schedule, reporting format, and parts supply agreement.

Key Commitment:

Condition monitoring covering vibration, thermal, and electrical parameters.

Three Ways to Engage

The right model depends on how urgently you need the unit back in service, whether you have a spare in hand, and whether you want a one-off repair or an ongoing programme.

Model 01

Repair and Return

How It Works

You send the failed unit. We inspect, repair, test, and return it with a test certificate and a 12-month warranty.

Best Suited For

Planned maintenance overhauls, non-critical failures with spare availability, and units being refurbished.

Typical Turnaround

72 Hours for critical items

Model 02

Unit Exchange

How It Works

You send the failed unit and we immediately dispatch a reconditioned equivalent from our exchange pool.

Best Suited For

Critical failures where immediate return to service is required and downtime cannot exceed a few hours.

Exchange Pool Items

Bridge rectifiers, SCR assemblies, GE electronic modules.

Model 03

Contract Maintenance

How It Works

We manage maintenance across agreed components using a structured, calendar-based programme.

Best Suited For

Fleet operators aiming to eliminate unplanned failures and ensure continuous engineering support.

What Is Included

Aligned schedule, condition monitoring, guaranteed parts availability.

The Case for Restoring
What You Have

For railway operators, a diesel-electric locomotive is a multi-crore asset. When electronic systems become unreliable due to obsolescence, the choice is simple. Rehabilitation restores full performance, while a new vehicle delivers the same output at four to six times the cost.

For mining operators, haul trucks and extraction equipment are high-value assets. Electronic failures disrupt production and cost far more than the repair itself. Condition-based monitoring and preventive maintenance turn unplanned breakdowns into predictable, budgeted activities.

For marine operators, isolation at sea makes on-demand repairs impossible. Failure of electronic systems is not an option. Pre-departure inspection and overhaul of critical components is the most reliable approach.

15–25%
Cost of electronic rehabilitation vs new asset

Restores sound assets to full performance at a fraction of new vehicle cost. Based on ALCO and EMD outcomes.

15+ Years
Typical service life extension

Assets with obsolete electronics are often strong candidates for rehabilitation rather than replacement.

72 Hours
Target turnaround for critical overhaul

Subject to parts availability. Exchange pool available for critical rectifiers and modules.

From Contact to Commissioning

A defined, documented process from first contact through to unit return. Every stage has a timeline commitment and a named output. You are never waiting without knowing where your unit is in the process.

Frequently Asked Questions

No. We accept single units for overhaul and diagnosis. For larger volumes, framework agreements with preferential pricing and priority turnaround are available on request.
If the cost of repair exceeds the unit's value, we will advise you in writing with reasons. We won't proceed with a repair that isn't economically justified and will advise on reconditioned replacements if available.
Yes. It covers failures due to workmanship or materials used in the overhaul, applying from the return date. If it fails in service within the period due to a covered cause, we repair or replace it at no charge.
Yes. On-site diagnostic inspection visits and commissioning support are available across India. For large programmes, we can deploy a technician team to your depot for an agreed period.
Units should be packed securely, with part number and fault description clearly labelled. Fragile units like display assemblies should be in anti-static packaging. Please include the pre-intake checklist with the unit.
