  First development by KTR think tank
 KTR have developed a new all-rounder coupling exploiting a new and very broad range of applications in areas relating to main and auxiliary drives in mechanical and plant engineering. The backlash-free and
torsionally soft EVOLASTIC will be available in ten sizes and each ten basic versions for nominal torques from 100 to 5,600 Nm.
The heart of the EVOLASTIC comprises
a non-slip elastomer element
transmitting the torque to the contacts
via vulcanized aluminium jaws. The
elastomer connections to the hub or flange are
ensured by radial and axial screw fittings. The
design assures reliable torque transmission along
with a precise prestress in the elastomer. The coupling requires low maintenance and is in a position to compensate for permanent angular misalignments of up to 3° in the homokinetic plane.
"Owing to its torsionally soft attributes, the EVOLASTIC attains the requested vibration and acoustic insulation in the
drive train. Besides torque transmission, the coupling also compensates for axial, radial and
angular misalignment and absorbs overloads elastically,” Jochen Exner, Innovation Manager in
KTR think tank in Hilden, Germany, says.
The EVOLASTIC expands KTR's coupling range by a backlash-free, torsionally soft all-rounder, for example for applications in frequency- controlled or I. C.- engine drives. The new
coupling will be available in ten sizes and each ten basic versions for nominal torques from 100 to 5,600 Nm.
 The EVOLASTIC is the first development to evolve from our think tank which opened in
Hilden in 2019. The next
coupling being developed in the think tank is already well on its way and will be introduced in spring 2021.

 Heavyline heroes headline for Hyundai at Hillhead
At Hillhead 2022, Hyundai Construction Equipment Europe will showcase its comprehensive range of heavy line equipment that has been purpose built for the Quarrying sector.
Headlining is the HX480AL 48-tonne crawler excavator which makes its first UK public appearance and will be at work in the demonstration area.
Powered by a fuel-efficient Stage V Cummins engine, the new machine boasts the highest engine power and hydraulic flow on the market. Its increased pump size enables the machine to work at lower rpm for greater fuel efficiency and there is no EGR valve requirement. 4-way proportional piping is available with hydraulic pressure and flow customisable on the cluster while the HX480AL’s stacked cooling system delivers improved cooling capacity. A reversable fan for automatic cleaning is a further boost in the demanding quarrying environment.
Showcased on the stand will be a series of further products from Hyundai
  Construction Equipment Europe’s heavy- duty wheeled loader, wheeled excavator and crawler excavator ranges –
including the latest A Series models.
