Tesmec surface miners are suitable to excavate even strong and unfractured rock, cutting vertical walls and square corners while producing low amounts of dust. Tesmec surface mining machines can be equipped with laser for grade control and/or GPS for auto steering and grade control. The high production capacity of the Tesmec Rock Hawg reduces the need of multiple units to a single unit working in the area, guaranteeing an easy job site to manage. The shock and vibration from the Rock Hawg excavation process is negligible, and therefore the danger zone to surrounding structures becomes a non-issue, according to the company. The special drum attachment with carbide diggings tools accompanied with the high engine power allows for a very efficient hourly output per each unit.
Tesmec Rock Hawg surface miners are employed for bulk excavation projects, continuous surface mining and open-pit quarry applications, such as:
- Quarries (surface mining).
- Excavation of big channels (large diameter pipeline).
- Bulk excavation of rock for construction and infrastructure such as ports, metro railway lines, big channels.
- Agricultural soil reclamation.
The Rock Hawg version of the 1150XHD model has been designed for continuous surface mining. Its 10-ft., 3-in. (312-cm) wide drum is employed in bulk-excavations projects and open-pit quarries. It has a 50-metric-ton-class operating weight, 440-hp engine, elevating cab, hydraulic stabilizers and TrenchTronic 3.0 equipped. It can work up-cutting or down-cutting by simply changing the attachment.
The Rock Hawg version of the 1475 model has been designed for continuous surface mining in rock, where its 12-ft. 6-in. (381-cm) wide drum is employed in bulk-excavations projects, open-pit quarries, and very large diameter pipelines. Equipped with TrenchTronic 3.0, the 1475 RH is Tesmec’s largest Rock Hawg featuring a 630-hp engine. It can also work up-cutting or down-cutting by simply changing the attachment.
