- The customer was so satisfied with the previous one we made that we received another order. This one is slightly smaller than the previous one, says Svein Krossli, project manager at Tratec Halvorsen.
Two men are assigned to the job, which takes around four weeks. Extensive testing must be carried out before the frame – which measures 2.43 by 1.60 meters – can be sent to the customer.
- It will be lift tested and all welding must undergo a thorough X-ray check, says John Vester Nielsen, head of fabrication at Tratec Halvorsen.
