The PX-420 ultra-large crawler excavator, with mining bucket and heavy-duty undercarriage, is built for open-pit mine loading and stripping.
The PX-420 is an ultra-large crawler excavator engineered for the most demanding production environments, including large open-pit mines, major quarries and heavy-duty earthwork and rockwork projects. With an operating class of 42–52 t and a mining bucket, the machine is built to handle large mine loading and stripping operations with high availability. Its heavy-duty undercarriage and robust structure provide the stability and durability needed for continuous operation.
The PX-420 features a heavy-duty undercarriage and reinforced working structure designed to absorb the loads of large-scale loading and stripping work. The mining bucket enables efficient handling of overburden and blasted material, while the hydraulic system is matched to deliver consistent performance in hard digging. Durable components and a robust chassis support long operating hours in severe conditions.
Power comes from a diesel configuration selected for the high output and reliability required in mine duty. Operating controls provide smooth, stable movement so operators can position loads accurately during truck loading cycles. Cooling, filtration and guarding arrangements suit dusty environments, helping the machine maintain productivity over extended campaigns.
