Springs in 2014 Queen’s Award Winner

The 2014 Queen's Award for Enterprise in Innovation has recently been awarded to Hill Engineering – a Newry based business – and, as always, it was very interesting to see the fundamental role that springs played within their winning design.


The innovation in question is a newly patented double locking hydraulic coupler, named 'Tefra', and this invention has been jointly hailed as the deciding contributor behind Hill Engineering's doubled workforce, and also a significant breakthrough with regards to the safety of semi-automatic couplers on construction sites too.

Used on a range of excavators, the Tefra is also far more robust than its predecessors due to an uncomplicated design, and according to an article on the Construction Index the Active Protection System upon this device is heavily reliant upon certain springs within its core mechanisms. Both coil and leaf springs are used within this award winning coupling, and each of these components brings something vital to the design.

The coil spring has been used to encircle the cylinder within the coupler, making certain that hydraulic problems – or even total failure – won't displace the correct positioning of the rear hook, whilst the leaf spring serves a similar function on the front hook. These springs mean that the hooks of the coupler will always remain aligned, and they also allow them to return to closed position in the safest possible manner as well.

This is far from the first time that springs have seen heavy use within a ground breaking new device, and similarly it is no surprise to see them being utilised to provide a mechanism with improved safety features. Here at European Springs, our torsion springs allow door hinges to 'bounce' enough to return to their original position, rather like the closing of the hydraulic coupling, and many of our other springs are used in crucial safety applications like car suspension too.
