Wirtgen’s ‘maximum milling’ HT22 quick-change toolholder system

Wirtgen’s HT22 quick-change toolholder system is said to ensure maximum milling performance and cost -fficient operation. A longer service life and fewer downtimes are achieved through various HT22 features, such as the significantly enlarged contact areas between the upper and lower parts of the toolholder system. Consequently, the high cutting forces are reliably transferred to the lower part of the system, substantially increasing the useful life of the milling drum. A larger shank cross-section a

2395 Wirtgen’s HT22 quick-change toolholder system is said to ensure maximum milling performance and cost -fficient operation.

A longer service life and fewer downtimes are achieved through various HT22 features, such as the significantly enlarged contact areas between the upper and lower parts of the toolholder system.

Consequently, the high cutting forces are reliably transferred to the lower part of the system, substantially increasing the useful life of the milling drum. A larger shank Cross-section and the optimised shank geometry increase the strength of the shank, thus providing greater resistance to undesired deformation. The maximum longitudinal wear of the upper part of the toolholder is also double that of the conventional version. Service intervals have now been extended from 250 hours to 500 hours thanks to the HT22 quick-change toolhandler system's more robust construction.

All new Wirtgen cold milling machines have been equipped with the new HT22 quick-change toolholder system since October 2013. Machines put into service earlier can easily be retrofitted with the new system, providing customers with the Ideal tools for future milling jobs.

    The latest equipment from Wirtgen has been used to recycle a stretch of Italy’s busy A4 Autostrada, one of the country’s most important highways. The Wirtgen machine was the first WR250 recycler/reclaimer to be delivered to Italy and was put to work on the A4 Turin-Trieste highway where it proved highly productive. The A4 Autostrada runs 522km from Turin to Trieste via Milan and Venice across northern Italy from west to east. The A4 is divided into five segments, the Turin-Milan, Milan-Brescia, Brescia-Pad
