Overview

The Cat® GH800 Plow System, previously known as the GH 9-38 ve system, has been the standard plow of choice since the early 1990s and is used in seams from approximately 0.9 m (35 in) up to 2.0 m (79 in), regardless of the inclination of the seam or the hardness of the coal. Caterpillar modified this already-successful plow model to create the new technologically advanced GH800B plow, with improved design features enhancing productivity in minimum seam heights below 1.0 m (39 in). The plow body of this next-generation machine has an optimized design that allows it to load more coal onto the face conveyor and reduces the amount of cutting power wasted in the process. The GH800B plow system with 2 × 400 kW (2 × 536 hp) installed power now covers mining heights from 750 to 1550 mm (30 to 61 in).
