A Solid Base for a Long Life - Strengthened undercarriage for higher durability even in heavy-duty applications. Increased Loading capacity of Swing Circle - The number of ball bearings in the swing circle, which sustains the upper structure, is increased to boost the loading capacity of the swing circle by approximately 6 %, allowing stable swing even in tough operation. (vs. Conventional ZAXIS 480MT / 480MTH)
- Enlarged Upper and Lower Rollers, Idlers and Sprockets - Upper and lower rollers, idlers and sprockets, used on the ZAXIS 500LC / 520LCH, are larger in diameter than those on the new ZAXIS 450LC / 470LCH. Undercarriage components capable of bearing a 60-ton class excavator are utilized to give sufficient strength and durability. This feature is suitable for work sites when the machine travels frequently.
- Increased Traction Force - On the ZAXIS 500LC / 520LCH, distance between tumblers is shortened, compared to that of the new ZAXIS 450LC / 470LCH, to increase traction force by 30 %.
- The feature is suitable for frequent hill climbing and traveling on hard ground surfaces.
- Full Track Guard Provided Standard (ZAXIS 520LCH) - On the H-specification machine, full track guards are provided standard.
- Full track guards protect track links and lower rollers from damage and deformation.
- Moreover, they also keep out stones, preventing the overload to the undercarriage to reduce wear and damage.
- 5 % Increase in Strength with Stronger Pin Material - The strength of pins, used in the arm and boom, is increased by 5 %, using harder steel material. (vs. Conventional ZAXIS 480MT / 480MTH)
- Strengthened H-Bucket for Heavy-Duty - The heavy-duty bucket is reshaped, and bucket parts are strengthened to increase durability.
