Strengthened undercarriage for higher durability even in heavy-duty applications

Track links are enlarged to increase strength for higher durability and reliability especially on rugged ground.

At the idler pedestal that sustains the front idler, its contact length is lengthened by approximately 90 % to increase strength and service life.

Thickened durable plates of idler brackets increase reliability of the idlers.

Tracks are strengthened for higher mobility by increasing roller width and diameter, sprocket tooth width, and idler width.

The travel devices are compactdesigned to reduce damage for higher mobility, reducing downtime.

The center track frame of integral cast steel structure can avoid stress concentration, and increase reliability.

The number of balls, in the swing bearing that sustain the upperstructure, is increased to boost the load-carrying capacity by approximately 6% (vs. conventional model). This improvement allows for smoother swing even in heavy-duty operation.

The oil cooler is separated from the radiator to effectively cool down hydraulic oil. This helps extend the service life of hydraulics.

Delivery filters, newly added to the delivery side of hydraulic pumps, effectively protect hydraulic lines from accidents.

Rock buckets are specifically strengthened to resist wear and impact.

Two grease-filled floating pins, at the boom top and at A linkage, increase the sealing ability, extend pin life, and reduce repair costs. Wear plates are provided on both sides of a boss at the arm top.
