High strength material Komatsu PC450 Excavator

Invincible mining hard rock, high overload efficiency

277kN bucket excavation force+233kN boom force, capable of directly excavating hard rocks, basalt, and granite without the need for blasting, with a crushing hammer efficiency 20% higher than its peers.
CLSS hydraulic+690L/min high flow, smooth and effortless compound action (rotation+walking+boom), fast loading/leveling speed, and a production capacity 5% -10% higher than that of the special 349.
The boom/arm is made of high-strength cast steel, thickened steel plate, and reinforced ribs, with an X-shaped reinforced lower frame. It is not easy to crack or deform under heavy loads in mines, and its service life is 30% longer than that of domestic products.

Strong power, low fuel consumption, and fast cost recovery

Komatsu 11L large displacement engine+257kW high power, 4500m plateau power without attenuation, no stalling or deceleration under heavy load/breakage.
The comprehensive fuel consumption is 18-22L/h, which is 2-3L/h lower than the Fiat 349 and 1-2L/h lower than the Hitachi ZX470; 650L large fuel tank, refuel once a day to reduce downtime.
The new machine costs about 1.8-2 million yuan, with high mining shift fees, low fuel consumption, and low failure rates. The payback period is about 8-10 months.
