City and municipal councils have a duty to take care of the safety of the entrusted building facilities. Nevertheless, how can an authority decide with certainty which mast is (still) technically suitable or where there is a risk of destruction?
Visual control, ultrasound wall strength measurement, or simple load are absolutely inadequate when it comes to the obligation to ensure the safe operation of a facility, or settling a claim for the damage caused.
The regular non-differentiated change of masts (e.g. as masts age) will cause unnecessarily high costs and enormously burden the municipal budget. Acute replacement is only necessary in 4%–6% of the tested masts. An economical solution is to separate the intact masts and thus eliminate potential risks. There is an uncomplicated, safe, and economical way out of this arduous situation in which almost every municipal administration finds itself!
Our solution – a legally binding test of strength and stability
Roch – Services GmBH is a DIN EN ISO 9001 certified testing laboratory, which has adequate competence in the field of strength and stability tests of masts. The Roch method is a globally patented and utilised non-destructive testing method for mast systems. It allows for the fast, uncomplicated, and inexpensive testing of strength and stability to meet the requirements of frugality and legal responsibility.
Cheap and efficient
The stability of mast systems consists of the mast’s strength and the stability of the bearing. The Roch method artificially elicits a wind load that forces the mast to bend. For the evaluation of the test, a diagram is drawn up by electric sensors (the dependence of the curves and shift on the force used), which is used worldwide for material testing. The Roch method examines both the strength of the material and the anchoring of the mast. This method is quickly feasible at the lowest possible costs, it is reliable, and it clearly defines the measurement results. This is a prerequisite for the test protocols of Roch – Services GmBH to serve to the full extent as evidence of the facility’s serviceability. The test can be carried out at any time and place by specially trained workers from Roch – Services.
The procedure and technology used (800,000 reviewed masts worldwide) are the exclusive property of the company Roch – Services GmBH.
The non-destructive testing method according to Roch is based on the universally recognised principle of metallurgical testing and the science of strength, which are globally used in all testing laboratories.
The Roch testing method combines the best of test design and measurement with the subsequent display and evaluation of the results.
Endangered areas in the stability of masts
This method can be used to carry out tests on metal, concrete, and wooden masts of all kinds (public lighting, motorway lighting, railway constructions, lighting of sports areas, etc.).
