Drillmasts
Updated: 13.02.2024
Marini drill mast attachments are available for a wide range of hydraulic excavators from 2 to 30 ton operating weight and can be equipped with rotary heads or drifters (top hammers) mainly for the installation of self-drilling anchors and micropiles. Key advantages of drill mast attachments are that standard excavators can be transferred to high-performance drill rigs and the extended working range in length of height which crawler drill rigs can't reach.
