What We Do

Complete Heavy Truck Care

From a roadside breakdown to a full engine overhaul, one team handles diagnostics, repair and parts — on your site or in our workshop.

On-Site

On-Location Mobile Repair

We bring the workshop to you. Wherever your truck stops — highway, depot or construction site — a fully equipped mobile unit is dispatched to get you moving again.

Diagnostic

Computerized Diagnostics

Modern trucks need modern tools. Our diagnostic computers read ECU fault codes accurately and fast, so we fix the real problem the first time.

Parts Desk

From filters and brake pads to engine components and electricals, we stock and source genuine, quality-assured parts for all major truck brands.

Workshop

Engine & Gearbox Overhaul

Full teardown, rebuild and re-certification of engines, gearboxes, clutches and drivetrain components by experienced heavy-vehicle technicians.

Workshop

Auto-Electrical Systems

Wiring faults, batteries, starters, alternators and lighting — diagnosed and repaired so your truck's electrical system is reliable in every condition.

Fleet

Fleet Maintenance Contracts

Scheduled servicing plans for logistics and transport companies, keeping every truck in the fleet inspected, compliant and on the road.

The Process

How On-Location Service Works

A breakdown is a real sequence of events — here's exactly what happens from your call to being back on the road.

1

Call or WhatsApp

Reach our hotline any time, day or night. Tell us your location and what the truck is doing.

2

We Dispatch

A technician and fully equipped mobile unit head straight to your location.

3

On-Site Diagnosis

We connect the diagnostic computer and pinpoint the exact fault before touching a tool.

4

Repair or Recovery
