Based on Epiroc’s well-proven SmartROC T35 surface drill rig and drawing on the company’s experience in developing underground battery rigs, the SmartROC T35 E comes with a range of smart features, and is said to deliver high safety, reliability, and performance – in a quieter working environment.

"The fact that we are removing emissions from the drilling process is an important step towards a better environment,” says Hakan Aytekin, vice president marketing, Epiroc Surface division.

“This accomplishment shows that Epiroc has an important role to play in making our industry more sustainable.”  

The SmartROC T35 E rig is equipped with both a battery and an electric cable, which improves flexibility considerably. Personnel can choose to drill with the most suitable alternative for the location. It also allows for quick and smooth transportation within and between sites.

The surface drill rig is fitted with the same type of well-proven batteries and sub-components as in the Epiroc underground battery solutions. This streamlines spare parts handling and service for customers with several different operations.

"SmartROC T35 E is a result of a successful collaboration between Epiroc and our customers,” says Ulf Gyllander, global product manager, Epiroc Surface division. “They have provided us with valuable input, making sure we will deliver a rig with optimised performance and flexibility.”  

Epiroc’s battery-electric solutions are said by the company to be attracting strong interest from the market. The machines play a vital role in the firm’s ambitious sustainability goals for 2030, which include halving the CO₂ emissions in operations and from sold products.  

In 2021, the goals were validated by the Science Backed Targets initiative as being in line with keeping global warming at a maximum 1.5°C, consistent with the goal of the Paris Climate Agreement.

New SmartROC T25 R surface drill rig from Epiroc

The SmartROC T25 R is a radio-remote rig built on a new platform and offers features including an exceptional coverage area, excellent terrain ability and application versatility. These are backed up by a smart Rig Control System (RCS) and future-proof digital functions that are designed to improve efficiency and help to reduce the rig’s climate impact through fuel savings.

The machine will be launched initially on the Scandinavian market later this year, with a full global rollout in 2024.

Global product manager Marcus Leu said the rig offers greater stability and balance to increase safety. “These rigs operate on unprepared ground, and we have lowered the centre of gravity,” he added. “The SmartROC T25 R has new features including the ability to drill sideways which enables applications such as small tunnels and vertical shafts.

“The machine offers a coverage area of 45m2 which is three times greater than the 15m2 that we currently have.”

Another new feature is being able to choose between rubber and steel tracks on the machine.

Epiroc is also rolling out an upgraded version of the advanced SmartROC T40 tophammer rig for quarrying and construction. It is claimed to consume less diesel than any other diesel-hydraulic rig in its class and offers superior performance even under the toughest drilling conditions.

The manufacturer says the rig’s fuel efficiency reduces environmental impact and costs. It also comes with smart features and options that boost productivity, including enhanced automation which helps to increase both drilling consistency and output.

In addition Epiroc is introducing the new DTH 5 hammer, which it says represents a significant upgrade that gives more drilled meters per shift and the versatility needed to tackle any type of rock and task. The design offers 12 configurations and a 5% higher penetration rate compared to its predecessor and lasts approximately 10% longer. For the operator this translates into more productive and profitable workdays with fewer time-consuming and heavy changes of tools.
