Plow chains up to 38 mm can be used, allowing installations up to 2 × 400 kW (2 × 540 hp). The plow guide has a maximum height to withstand the reactionary forces produced during the cutting process, yet it does not hinder coal flow during the loading process. The upper plow guide can be opened for quick and easy access to both the top and bottom chains for maintenance. Proven design and geometry, in conjunction with high-strength steel and optimized material properties, combine to ensure minimum wear for maximum life. Both gobside and face side pan connectors have a breaking strength of up to 3000 kN (330 tons), depending on the line pan being used. Maximum cutting depth at high plow speeds provides high productivity. Every point of contact between plow body and plow guide is designed as a wear part, again to facilitate maintenance.
