I sat with Martin and asked him some questions on the project.
How do you feel about the end product now that it has been launched?
“To be honest I’m feeling good about the new coupler, we had set ourselves some really difficult challenges by committing to develop a coupler for this machine range but I strongly believe we more than exceeded our goals.“
What were the challenges with creating a coupler of this size?
If you think about the pin centre range for a minute, it starts at 90mm, my current phone measures 140mm long!!! This gives you a sense of scale when you talk about the QC25-30.
All our current couplers moves in a totally linear direction but this simply would not work here, we needed to come up with a concept that would retain the advantages of our sliding system but allow us to get back to 90mm pin centre.
We solved this problem very simply by coming up with a ‘slide and rotate’ wedge action.
The wedge retracts past the 90mm pin position and then rotates upwards following a machined slot in our pick up fittings, that’s it!
Early on we realised that rigorous testing would be required to ensure confidence that the coupler could survive ‘on site’ and in all conditions.
We custom designed and built test benches in our workshop and I have personally spent many hours running a series of tests based on real life scenarios that we have met ‘in the field’.
This testing has been invaluable from a design point of view as it allowed us to make tweaks on small parts of the design but also gave us much more confidence in the product, it really is a product we can stand behind and be proud of.”
What was the feedback from the field during the testing & trial period?
