This system positions the plow chain on the gobside of the AFC, which makes it easily accessible for maintenance, a critical feature in low seam heights where working space is limited. The base-plate slides over the floor and underneath the line pans during operation. The integrated cleaning edge pushes coal from underneath the AFC back into the plow travelway. The cast plow guide is welded to the gobside of the face conveyor. Plow chains of up to 42 mm in diameter can be used, allowing the use of up to 2 × 400 kW (2 × 540 hp) installed power. Both gobside and face side pan connectors have a breaking strength of up to 2000 kN (220 tons), depending on the line pan being used.
PF line pans form the powerful backbone of the entire conveyor system. The pioneering conveyor technology and extremely rugged pan design have been subjected to extensive testing.
Two configurations are possible: A control in each shield (typically used) or one control shared by three shields in cases where fewer shield functions are required. The VCU (Visualization & Control Unit) not only controls the entire longwall, but also visualizes face operations on a graphic display, including position, actual coal load on the AFC (through AFC power consumption), shield position, leg pressure, stroke and plow position. The VCU provides a face-wide network and allows remote maintenance of shield components as well as data recording and transfer of data to the surface.
