Stone eScorpion –
for challenging work sites

Stonepower has developed the first fully battery-driven crawler drill rig in the world! It is an excellent solution for challenging drilling work in cities and other work sites where the benefits of the electric-driven eScorpion can be fully utilized.

Its superior advantages include CO2-free surface drilling, low noise level, compact size, wide reach and coverage, 350-degree turning superstructure, and rough terrain capabilities. In addition, it is capable of operating underground as well.

eScorpion offers a large selection of options to choose from depending on the work requirements. In addition to conventional drilling applications, you can also choose, for example, a drill & split boom, water mist system for dust control, or an extra noise silencer on your eScorpion.

eScorpion is excellent for bolting, and vertical or horizontal drilling at construction sites, canals, tunnels, mines, and stone quarries through all seasons. The machine is the only one on the market to have the integrated drill & split application available. eScorpion can operate with high precision in small spaces thanks to its agility.

The 400 VDC 120 kWh battery with safe and long-lasting LFP chemistry ensures a long service life. eScorpion is PowerPack- ready and supports 93 kW CCS fast charging, which can charge the battery from empty to full in up to two hours.

22kW Type-2 charging can also be used during operation. The advanced permanent magnet motor control saves energy, and CAN-controlled LS hydraulics guarantee precise and efficient operation.

No CO² emissions or exhaust gases.

Low noise levels reduce noise pollution.

No fuel costs, and maintenance expenses are significantly lower compared to combustion engine machines.

The simplicity of the electric machine reduces the need for servicing and allows for longer maintenance intervals.

Fewer maintenance points mean less downtime and improved productivity.

Safe to use in tunnels, buildings, and other confined work environments.

A single charge provides approximately 4 hours of operation. Maintenance charging enables continuous work. Batteries can be charged using low current (16A or 32A), which is typically available on job sites.

A broad selection of accessories is available for different work phases, including a Drill & Split wedging boom, drill beam noise reducer, water mist system, drill bit sharpener, measuring devices, and even custom colors upon request.

We also design and manufacture special equipment tailored to customer needs, such as reinforcement attachments. Feel free to contact us for more information!
