Wear plate and clamping sleeve geometry
The unique grooved profile of the wear plate with its innovative centring function reduces wear and increases the service life of round-shank picks and pick holders. In addition, the wear plate has been upgraded to heavy duty and its shape has been optimised to provide maximum protection of the pick holder
The new, short clamping sleeve geometry minimises mechanical loading on the clamping sleeve and assures optimal clamping force throughout the entire service life. The wear plate geometry, with the grooved profile on the underside, is an essential feature of GENERATIONC² round-shank picks and enables positive locking of the pick in the pick holder.
The transmission of force from the pick into the top part of the pick holder takes place via the WIRTGEN wear plate with the centring groove and the optimised pick shank with the shortened clamping sleeve. In contrast to the case with conventional picks, this reduces the load on the clamping sleeve and increase the service life. Thanks to the minimal play and ideal centring of the pick, this also increases the service life of the top part of the pick holder.
