Overview

The SANY STR series is the heavy-tunneling arm of the roadheader family, built for longer, continuous drives in coal, semi-coal and rock seams. Two models — STR260/5 and STR318/5 — cover the mid-to-heavy heading class.

Cutting motor power is 260 kW on the STR260/5 and 318 kW on the STR318/5, with total system power of 467 kW and 570 kW respectively and operating weights of 80–115 t. Both share the STR platform's efficient loading and conveying, high-reliability hydraulics, intelligent electric control, automatic cable winding and centralised lubrication, engineered for headings 3.6–6.8 m wide.

Automation and central lubrication reduce operator workload and unplanned stops on long tunnels. SANY supplies operator training, cutting tools and field service through its mining support network. Tell us your seam and planned face advance rate for the right STR model and a quotation.
