Non-Destructive Testing (NDT)
HTT offers a variety of Non-Destructive Testing (NDT) services to detect defects in materials, products, installations, equipment, and hoisting structures without damaging the objects.

Hoisting and lifting equipment
Under the Dutch Working Conditions Act and the Commodities Act, companies are personally responsible for the maintenance and timely inspection of all hoisting and lifting equipment.

We perform the tests required by the relevant laws and regulations, such as ISO 1496 or DNV 2.7-1.
The Dutch Working Conditions Act and Commodities Act place the responsibility of maintenance work and the timely inspection of hoisting and lifting equipment with the entrepreneur himself. Besides that you want to observe the law, it is important for entrepreneurs to guarantee the safety of hoisting and lifting equipment. During an inspection we check whether the hoisting and lifting equipment still comply with the safety requirements.
Three types of inspections are necessary to guarantee the safety of your work equipment:
- Daily inspection by users:
Every day before use the user must check the item regarding visible defects and/or damage. Then the user decides whether this item is safe for use, so that the safety can be guaranteed for himself and his environment. - Annual inspection by expert:
Every year an expert must assess the condition of hoisting and lifting equipment. This expert assesses whether it is responsible to use the hoisting or lifting equipmentin the following year. The intensity or method of use can also be examined for each hoisting and lifting equipment. As a result it may be decided to reduce the validity of this inspection. - Four-yearly inspection including test:
Every four years a hoisting and lifting equipmentmust be tested by a professional body. On the basis of the tested results, which are tested according to fixed (rejection) criteria, it is assessed whether the further use of the hoisting or lifting equipmentis sensible, whether the equipment should be repaired or rejected.
A few examples of hoisting and lifting equipment which we tested in the past include:
- Chainwork (2.3.1)
- Hoisting belts & round slings (2.3.2)
- Hoists & winches
