Hard-wearing picks for tough applications
Selecting the right pick is of vital importance both for high cutting performance and for the service life of the pick itself. The pick head diameter, pick head length, carbide diameter and additional armouring are selected individually, based on the material properties and rock hardness, in close cooperation between the customer and WIRTGEN experts.
Different carbide geometries are also used in surface mining due to different fields of application and materials to be cut. Mushroom-shaped carbide tips protect the steel body against erosion; cylindrical carbide tips are used in hard materials.
