Quality & certification

We prove lifting gear by testing it. Every sling and assembly we make is proof-loaded on our own machines and certified on its serial number, and every component is traceable to its own certificate.

  • Proof-load test bed up to 1,200 T
  • Class-witnessed: IRS · ABS · LRS · BV
  • Certificates in our own name

From material to certificate

How we control quality

Five checks between the mill and your site.

01

Certified material

Wire rope arrives with the mill certificate; components with the maker's certificate.

02

Traceable components

Every component in an assembly is traceable to its own certificate.

03

Made in-house

Slings are terminated in our works — swaged, spliced, socketed or sewn.

04

Proof-loaded

Each assembly is loaded to the multiple its standard requires, on machines from 1 to 1,200 T.

05

Certified

A certificate in our own name on the serial number, class-witnessed where the job needs it.
