Epiroc PowerROC D55 Surface DTH Drilling Rig 90-152mm

Product Overview

The Epiroc PowerROC D55 is a reliable and cost-efficient surface down-the-hole drilling rig developed for mining, quarrying and production drilling applications.

Designed for hole diameters from 90 to 152 mm, the PowerROC D55 supports drilling depths of up to 30 m with its hydraulic rod adding system. It is compatible with Epiroc COP 35, COP 44 and COP 54 DTH hammers, making it suitable for a wide range of hard-rock drilling conditions.

The rig is powered by a high-output diesel engine and equipped with an integrated compressor system to provide the airflow required for efficient DTH hammer operation. Depending on market configuration, engine and compressor specifications may vary.

PowerROC D55 is designed around a straightforward and proven machine concept. Its simplified electrical and hydraulic systems, easily accessible service points and intuitive cabin interface help make daily operation and maintenance easier.

The heavy-duty crawler undercarriage and strong terrainability allow the rig to work effectively on uneven mining and quarry sites, while the robust feed system helps maintain straight-hole drilling and consistent penetration performance.

For contractors and quarry operators, the PowerROC D55 offers a practical combination of productivity, reliability and easy maintenance for demanding surface drilling operations.
