GENERATION Z picks excel due to unique product features, which, most importantly, reduce operating costs. Thanks to their adapted shank design and optimised carbide tip geometry with a reinforced carbide base, the picks in this product line are designed to withstand high impact loads and are thus the ideal solution for recycling and stabilising applications. The relatively large steel body volume compared to conventional picks and the reinforced wear plate deliver the longest possible service life for tools and optimum protection for the upper part of the toolholders in applications involving abrasive materials.
1 Greater fracture resistance in the carbide tip thanks to improved carbide composition and an adapted tip geometry.
2 Greater wear volume in the steel body as a limiting factor ensures the carbide is fully exploited on the pick.
3 Improved tensile strength in the pick shank thanks to the repositioning of the clamping sleeve bearing on the lower end of the pick shank.
4 Greater hardness in the wear plate ensures maximum toolholder protection.
5 Time-tested WIRTGEN clamping sleeve in reinforced design ensures that the pick is permanently and dependably secured in the toolholder bore.
The optimised carbide mix improves carbide tensile strength. The lower pick head height in GENERATION Z reduces the siphon effect, thus improving the tensile strength in the pick shank in the face of impact loads. The larger volume in the wear-critical section and the greater hardness in the wear plate not only extend the expected longer service life for the pick, but also enhances toolholder protection.
The clamping sleeve in GENERATION Z ensures optimal tool rotation behaviour thanks to its precise round shape.
Compared to the previous model with shanks 22 and 25 mm in diameter, the pick shank fracture tendency is minimised in the GENERATION Z by about 45%. This is achieved by offsetting or displacing the stops from the centre to the bottom of the pick shank (see left picture)
