Regulation-aware engineering before official approval processes.
TLG SYSTEMS supports manufacturers with technical drawings, regulatory pre-checks, engineering documentation and preparation work before official testing, approval and technical service processes.
- R107 preparation support
- R118 material documentation support
- R66 design inputs
- CoC documentation support
- VECTO documentation support
- COP documentation support
- Technical drawing package support
- Testing and technical service coordination support
Pre-Homologation Risk Review
We review vehicle architecture, door arrangement, seating layout, emergency exits, system packaging, weight distribution and documentation gaps before the project reaches the official approval stage.
View homologation support →Engineering-driven production support.
Our engineering approach is supported by practical manufacturing know-how for vehicle components, door mechanisms and mechanical subassemblies.
Mechanical Manufacturing
CNC machining, sheet metal fabrication, bending, welded assemblies and mechanical component manufacturing.
View capabilities →Door Mechanism Assembly
Assembly-oriented support for door mechanisms, actuators, mounting components and project-specific mechanical solutions.
View door systems →Prototype Support
Prototype part production, design for manufacturing reviews, production feasibility checks and engineering support for early-stage vehicle projects.
View engineering services →We understand the component and the vehicle around it.
Vehicle projects fail when components are selected without understanding chassis limits, door apertures, seating layout, axle loads, system packaging, production tolerances and homologation risks. TLG SYSTEMS approaches vehicle engineering from a complete bodybuilder perspective.
Bodybuilder-focused engineering
We support manufacturers with practical engineering outputs that consider vehicle layout, manufacturability, system integration and production constraints.
Door system expertise
Our access system know-how allows us to evaluate door openings, mechanism packaging, emergency release concepts, vehicle signals and operational requirements together.
