4 Units CAT 320 GX 20 Tons Crawler Excavator For Ghana

Recently, an established gold mining contractor operating in Ghana's Western Region contacted our export team during preliminary procurement for a major alluvial concession expansion near Tarkwa. To secure rapid overburden clearing and steady trommel feed rates while keeping daily overhead manageable, they required modern 20-ton excavators featuring proven mechanical durability and high fuel thriftiness. After evaluating their production schedules and local operating costs, we proposed a fleet solution built around the CAT 320 GX Crawler Excavator. Confident in the machine's electro-hydraulic agility and outstanding investment payback, the client finalized the purchase of 4 units.

 

 

Running heavy excavation fleets across Ghanaian gold concessions involves harsh mechanical and environmental hurdles. Primarily, open-cast pit benches and alluvial river basins feature compacted ferric laterite hardpans and sharp quartz gravel veins that impose severe wear on ground-engaging tools and risk track derailment during sudden torrential downpours. Furthermore, the equatorial climate subjects machinery to fierce equatorial heat often climbing past 38 degrees Celsius, paired with abrasive silica dust and dry seasonal Harmattan winds that rapidly foul filters and exhaust operators. Above all, high domestic diesel retail prices directly squeeze extraction margins, making heavy-displacement, fuel-inefficient machines a major financial liability.

 

 

To effortlessly conquer dense laterite overburden and abrasive quartz rock, the CAT 320 GX integrates a robust Cat C4.4 turbocharged engine delivering 103.6 kW net power with high torque output at low RPMs. This dependable powerplant drives a next-generation electro-hydraulic distribution system with an electronic main control valve, delivering 429 L/min pump flow instantaneously to eliminate hydraulic pilot lag and ensure fluid boom-and-swing coordination. Supported by a heavy-duty undercarriage with integrated full-span track guiding guards to protect rollers on rough pit haul paths, and armed with a 1.0 CBM reinforced rock bucket generating 136 kN breakout force, the machine sustains rapid cycle times even under heavy mineral loads.

 

 

Beyond heavy digging capability, the CAT 320 GX provides exceptional operating economics and operator endurance in challenging tropical mining climates. Through its automated Smart and Power operating modes, the machine dynamically balances hydraulic flow with actual digging resistance, reducing hourly fuel consumption to approximately 11 to 12 liters and cutting total diesel expenses by 15% to 20% compared to legacy excavators. For driver protection during intense 12-hour shifts, the sealed ROPS pressurized cab features high-capacity tropical air conditioning, an ergonomic suspension seat alongside a modern high-resolution touchscreen, effectively blocking airborne silica dust and scorching midday heat. Coupled with grouped ground-level fuel filtration and water separators, routine servicing is completed rapidly, maximizing fleet uptime and accelerating capital recovery for the contractor.
