Unit: mm
Metric measure
Notes: 1. Ratings are based on ISO 10567.
2. Lifting capacity of the ZAXIS Series does not exceed 75 % of tipping load with the machine on firm, level ground or 87 % full hydraulic capacity.
3. The load point is the centre-line of the bucket pivot mounting pin on the arm.
4. *Indicates load limited by hydraulic capacity.
5. 0 m = Ground.

Versatile excavator with adjustable width for efficient use in various applicationssmooth movement in confined spaces, as well as powerful operation in open areas
Rear end Swing Radius: 675 mm
Minimum Width: 980 mm
Powerful Engine
Compact Body with Short Rear End
The compact short rear end design allows efficient operation even in confined spaces.
Adjustable Foot Crawler and Blade
The unit width is adjustable from 1 280 mm to 970 mm during jobs for travelling in narrow spaces, thanks to the adjustable foot crawler. Pin-detachable blade provides easier width adjustment.
Powerful Operation
Three-Cylinder Engine with More Powerful and Larger Exhaust Capacity
Two different travel speeds are available: high (4.3 km/h) and low (2.4 km/h) making transport of the machine through the jobsite more efficient and smooth. A new tread pattern has been applied for the rubber shoe and operating vibration has been suppressed.
Engine rated power: 11 kW
Total piston displacement: 854 mL (cc)
Hydraulic Pilot Control Levers
Hydraulic pilot operation levers provide smooth control and easy operation.
Two Travel Speeds Provided
Two different travel speeds are available, making transport of the machine through the jobsite more efficient and smooth.
Additional Counterweight (Optional)
An additional counterweight is also available for increased stability.
Additional counterweight: 80 kg
Comprehensive Durability Features
D-Shape Frame Protects The Body from Mechanical Shocks
D-shape cross section frame is attached all around the lower end of main body. This shock-proofing feature (patent pending) protects the body from unexpected shocks.
Enhanced Rubber Shoe
The new tread pattern applied for the enhanced rubber shoe delivers greater durability.
Strong Boom Cylinder Cover
Ribbed and reinforced boom cylinder cover provides higher impact resistance.
Large Single Pin for Swing Post
The vertical pin of the swing post employs a large single pin for reducing backlash.
HN Bushing
Reliable, job-proven HN bushings are used at all pin joints at the front and the blade. The lubrication intervals have been extended to 500 hours, contributing to reduced scraping and grinding of the pins and bushings.
