Engineering-driven solutions for passenger vehicles, door systems and vehicle integration.
TLG SYSTEMS is an engineering and manufacturing company focused on door systems, mechanical components, control units, electric drive solutions and vehicle engineering services for buses, minibuses, midibuses and commercial passenger vehicles.
Built on real vehicle engineering experience
TLG SYSTEMS was not established around a generic product catalogue. It was built on practical engineering experience gained through real vehicle projects, production constraints, platform limitations and integration challenges.
Our background includes engineering work on vehicle projects based on platforms such as Mercedes-Benz Sprinter, Iveco Daily, Mercedes-Benz Atego, Skywell electric chassis and DAF XB. This experience has shaped the way we design, manufacture and integrate systems for different passenger vehicle projects.
For us, engineering is not only about creating drawings. It is about understanding the chassis, body structure, passenger layout, door position, axle loads, service access, production method and regulatory requirements as one complete system.
Our standpoint
We approach each project not only as a component supplier, but as a technical solution partner that understands the complete vehicle.
A door system is not simply a mechanism that opens and closes. It is a critical vehicle interface affecting passenger safety, driver control, accessibility, vehicle ergonomics, long-term reliability and perceived production quality.
This is why our work focuses on practical integration, durable mechanical design, vehicle signal coordination, serviceability and project-specific adaptation.
What we do
TLG SYSTEMS develops configurable technical solutions for coachbuilders, vehicle body manufacturers, bus and minibus producers, vehicle converters and passenger transport vehicle projects.
Door Systems
Single-leaf, double-leaf, outward-opening and sliding door systems for minibuses, buses, midibuses and rail-related vehicle projects.
Control Units & Electric Drives
Door control units, electric motors and vehicle signal integration solutions developed for project-specific vehicle requirements.
Mechanical Components
Brackets, mechanism parts, welded assemblies, connection elements and custom mechanical components for passenger vehicle projects.
Vehicle Engineering
Support for chassis feasibility, packaging, seating layout, door integration, weight calculations and technical documentation.
Engineering approach
At TLG SYSTEMS, engineering starts with design but must be validated through production, installation and real vehicle use. A part that looks correct on a drawing is not sufficient. It must work correctly on the vehicle, be practical to install, remain accessible during service and perform reliably over time.
| Engineering Area | What We Consider | Expected Output |
|---|---|---|
| Vehicle Platform | Chassis dimensions, body interface, axle loads, packaging limits and production constraints. | A feasible vehicle concept aligned with the selected platform. |
| Door Integration | Entrance position, mechanism movement, sealing area, passenger flow, vehicle signals and service access. | A door system that is configured for the specific vehicle project. |
| Mechanical Design | Strength, stiffness, tolerances, installation points, production method and long-term durability. | Manufacturable and serviceable components for real operating conditions. |
| Technical Documentation | Project requirements, vehicle layout, integration details, homologation support data and engineering records. | Clear technical documentation to support production and approval processes. |
Our vision
Our goal is to position TLG SYSTEMS as a reliable engineering and manufacturing partner from Türkiye for international passenger vehicle projects.
We aim to transform our experience in door systems, mechanical components and vehicle engineering into safer, more accessible, better integrated and more sustainable public transport solutions.
Each product and engineering service we develop today is part of a wider roadmap for future minibus, midibus, bus and special passenger vehicle projects.
Our difference
TLG SYSTEMS combines field-based engineering experience with practical production capability. We do not look at a vehicle as isolated components. We evaluate the complete technical environment around the system.
This approach allows us to support vehicle projects with door systems, control units, electric drive solutions, mechanical components and engineering services that are configured according to real project needs.
We produce more than parts. We contribute to vehicle safety, accessibility, production quality and engineering value.
