The GH800B represents a modification of the successful HBT gliding plow system. It comes along with improved design features enhancing productivity in minimum seam heights below 1.0 m (39 in). The GH800B plow system with 2 x 400 kW (2 x 540 hp) installed power now covers mining heights from 750 to 1550 mm (30 to 61 in).
The plow body of the GH800B has an optimized design which allows loading more coal onto the face conveyor and reduces the amount of cutting power wasted for this process.
The plow guide which connects the plow to the conveyor is made from a one-piece casting. This provides extra strength and durability while being much lower in height than the previous welded plow guide version.
Another feature maintained is the conveyor with new plow line pans featuring a replaceable top trough for easy replacement of worn-out wear parts.
Further improvements are external dogbone connectors between the line pans with a breaking strength of up to 3 600 kN (367 tf) as well as a very strong and flexible relay bar between conveyor and roof supports.
Inspection doors in every second line pan enable quick and easy access to both the top and bottom chains for maintenance. Furthermore, a widened conveyor cross-section with extended side plates increase the coal throughput. The GH800B allows higher production rates in low seams — depending on the geological conditions and other parameters.
