Main Chassis
The main chassis of the machine is a robust box-type structure of high-strength steel construction that provides the following:
Mounting of the RH and LH crawler tracks and their independent drive systems and take-up provisions.
Independent pivots for mounting the cutting head and gathering head and conveyor components and their associated hydraulic cylinders for articulation.
An integral hydraulic oil tank along with two electric motor/hydraulic pump assembly‘s and associated valves and piping.
A rear stabiliser and its articulating hydraulic cylinder for improving leverage forces during sheardown in the cutting sequence.
Mounting provisions for all major electrical system components and their associated wiring.

Cutting Head Assembly
The cutting head assembly is attached to the main chassis at RH and LH independent pivot points around which the assembly is articulated for vertical-ranging cutting of the coal seam.
The independent pivots allow removal of the cutting head assembly without disturbing the gathering head or conveyor components.
The cutting head assembly consists of the following:
The cutting head support frame, a robust box structure which includes the RH/LH pivot points for attaching to the main chassis, upper mounting clevises for the two cutting head raise cylinders, and a major bolting flange to which the cutting head drive assembly mounts.
The cutting head gear case assembly, which consists of a input gear case and water-cooled 173 kW AC electric drive motor for each of the RH and LH sides, a final drive gear case which includes drive gearing, a main drive shaft and mounting points for the 1067mm diameter RH, LH, intermediate and centre drums, and a major bolting flange for mounting onto the cutting head support frame. The outer cutting drums are independently mounted to the major bolting flange and have an extension/retraction of 300mm each side from 5400mm to 4800mm and can be removed as an assembly.
The cutting head assembly is raised and lowered by two (2) heavy-duty hydraulic cylinders mounted to the main chassis at their lower ends and attached at their upper ends to main longitudinal structural members of the cutting head support frame. These cylinders enable the cutting head assembly to range from 249 mm below ground level to a maximum height of 4100mm.
The power train of the cutting head consists of RH and LH sides, which tie together at the common main drive shaft, allowing the combined power of both electric drive motors to be available at any point on the cutting drums.

Gathering Head Assembly
Gathering Head Assembly
The gathering head assembly is attached to the main chassis at RH and LH independent pivot points around which the assembly is articulated to adjust the gathering head for uneven floor conditions and for tramming the miner from place to place. The independent pivots allow removal of the gathering head assembly without disturbing the cutting head or discharge conveyor.
The gathering head assembly includes the following:
The gathering head structure consists of RH/LH pivot points for attaching to the main chassis, upper mounting clevises for the two gathering head raise cylinders, extendible plows compatible with extendible widths of the cutter head widths and shields mounted on rear of structure to support the roof bolting rigs.
RH and LH power trains, each of which include a water cooled 38 kW AC electric motor, an input gear case and a gathering head pot which drives a rotating centrifugal loading arm device. Mounting provisions for the Temporary Roof Support (TRS) systems in the shields.
The gathering head assembly is raised and lowered by two hydraulic cylinders, which are mounted to the main chassis at their lower ends and attached to points of the gathering head structure at their upper ends. These cylinders allow vertical ranging of the forward edge of the gathering head from 200 mm below floor level to 537 mm above floor level.
The RH and LH power trains are connected to a common foot shaft which provides
(a) Proper timing of the rotating CLA loading arms and
(b) Drive power to a sprocket which drives the conveyor chain. This conveyor chain drives is reversible to aid in clearing debris which might restrict conveyor chain movement
The gathering head structure includes a special noise-damped running deck for the conveyor chain to minimise noise generation
