Rugged Testing for Harsh Work Environments

DGUV V3 Inspection for Trades & Manufacturing

Avoid downtime. Ensure safety in the workshop & operations.

Electrical equipment in workshops and manufacturing facilities is exposed to particularly high stress. We test your equipment in a standard-compliant manner throughout Greater Munich – from Dachau to Starnberg. Typically several hundred heavily used devices per site.

Harsh Working Environments

In workshops, inspection intervals are often shorter than in offices (usually every 6–12 months). We inspect hundreds of heavily used devices and machines directly on-site using rugged test methods.

On-Site Repairs

Downtime costs real money in the trades. If plugs or cables are damaged, we typically carry out necessary repairs immediately and cost-effectively on-site.

Inspection of construction equipment and installations

Site Power & Machinery

We inspect trade businesses and manufacturing sites in Munich and the surrounding area, including construction power distributors and fixed machinery with RCD testing.

Ladders and racking inspection

Everything from One Provider

Save time: in addition to the electrical inspection, we handle the legally required inspection of your heavy-duty racking (DIN EN 15635) and ladders in the same appointment – practical and hassle-free.
