Interview with Designers of the Ultra-Large Excavators
The cutting-edge technologies for downtime and maintenance cost reduction, developed on the world-class EX8000 Ultra-Large Excavator, are adopted to the New EX-6 Series Giant Models.
ZAXIS670LCH
A Solid Base for a Long Life
Strengthened undercarriage for higher durability even in heavy-duty applications.
Strengthened Undercarriage
Increased Loading Capacity of Swing Circle
The swing circle ball bearing utilizes more balls to boost the loading capacity of the swing circle by approximately 7 %, allowing stable swing even in tough operation.
Enlarged Upper and Lower Rollers, Idlers and Sprockets
Upper and lower rollers are widened to increase contact areas, and idlers and sprockets are increased in diameter for more durability and mobility.
Strengthened Track Links
Track links are enlarged for higher strength, durability and reliability to allow tough operations on rough terrain.
Strengthened Idler Pedestal
The bearing length of the idler pedestal is extended by approximately 84 % to increase durability and service life. (vs. Conventional Model)
Strengthened Idler Bracket
The idler bracket is thickened for rigidity to prevent deformation and increase durability.
Pressed Master Pins
The master pin of each track link is pressed, instead of master pin using a pin retention to avoid disengagement.
Full Track Guard Provided Standard (ZAXIS 670LCH)
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.
Strengthened Front Components
Enlarged Pins
Pins, used throughout the front attachment, are increased in diameter for strengthening.
Strengthened Arm and Boom
The arm and boom are strengthened by thickening and using stronger material.
Strengthened H-Bucket for Heavy-Duty
The heavy-duty bucket is reshaped, and bucket parts are strengthened to increase durability.
Strengthened General-Purpose Bucket
Bucket teeth are reshaped as Super-V teeth for smooth penetration and higher production. Bushings are utilized at both ends of a bucket pin to eliminate clearances, preventing jerky operation.
