Kernkompetenz

Cable harnesses that perform under extreme conditions.

Special vehicles are not series products. Every cable harness is a one-off, developed for specific installation conditions, environments and standards. We deliver from batch size 1 — with the same process quality as in mass production.

Rescue

Emergency & fire vehicles

Cable harnesses for ambulances (RTW, KTW, NEF), turntable ladders and rescue fire engines. Heat-resistant up to +125°C, vibration-resistant per DIN EN 60068-2-6, IP67-rated. Customer example: harnesses for body builders with 120+ individual lines per vehicle.

Municipal

Municipal & specialty vehicles

Sweepers, refuse vehicles, winter service equipment. Cable harnesses with cable-chain capability, flex cycle resistance >1M cycles and chemical resistance to road salt and hydraulic oil.

Construction

Construction machinery & cranes

Excavators, wheel loaders, mobile cranes, concrete pumps. Extreme vibration up to 10g, temperature swings -40°C to +105°C, IP69K rating for high-pressure cleaning. Cross-sections up to 95mm² for starter motor connection.

Military

Military special vehicles

Armored vehicles, command systems, mobile communications. EMC-shielded harnesses per MIL-STD-810, NATO-coded. Highest reliability requirements at minimal tolerances.

Transport

Heavy duty & special transport

Low-loaders, heavy-duty cranes, special trailers. Cable harnesses up to 25m long, high-current connections up to 400A, multi-conductor hybrid lines for simultaneous power and data transmission.

Body

Custom bodies

No two vehicles are alike. We develop cable harnesses to your drawings or jointly with you at CAD. From single piece to short series — with first article inspection report and series documentation.

Fertigungstechnologie

Why laser soldering makes the difference.

Our factory in Shanghai uses laser soldering — a technology rare in mid-sized companies, with decisive advantages over conventional soldering.

Laser soldering vs. hand soldering

Contamination-free, reproducible solder joints. No flux residue, no thermal damage to adjacent components. Ideal for safety-critical applications in emergency and military vehicles.

Automated Crimping

Crimp stations with integrated force-distance monitoring. Every crimp is checked against target values in real time — defects are automatically detected and rejected. Pull-force testing per IPC/WHMA-A-620.

Complete harness for ambulance generation 2025

A new ambulance generation with 40% more sensors was about to delay series launch. We developed a 142-conductor hybrid harness with EMC-shielded data bundle, IP69K connectors and laser-soldered safety connections — at significantly lower unit cost.
