Who are we?

IDMAT is Manufacturer of lifting and lashing slings, lifting grips for building and negotiating mounting parts for more than 20 years. This is also the main company of ARRACH Holding group. LTL (Technical laboratory for lifting) is also part of the group.

IDMAT is the French market leader in the manufacture of chain slings G100 and G80 (roughly 30,000 parts per year). LTL is a Lifting Engineering Lab integrating tests under COFRAC and VGP mobile inspection. With Idmat you get a real 10.204 standard certificate up to 3.2.

Thanks his Integrated Research and Development Department (CAD/CAM/3D printer) which has just developed and patented its new BLOKMI shortening hook which can be unlocked with just one hand.

The self-locking BLOKMI® shortening hook will replace the traditional hook and safety pin from 2022 onwards.

The idea is simple: Currently, the safety pin is frequently removed by operators to make it easier to install the unit and save time. However, stowing standards require that it be used.  This leads to a safety problem for people and a stowing problem for goods.


To solve this recurring problem, a problem we have seen in the field and in our workshops, the ID MAT design office has developed an innovative alloyed steel hook which is both ergonomic and ultra-robust. This hook locks automatically and can be unlocked with one hand, using the sliding trigger. It’s easy to use: A single person can install it with no physical effort.
