  The new model offers further work convenience in restricted areas, operational comfort and safety, as follows:

■Features
  (1)

Improved Working Convenience in Restricted Areas
Compactness of the implement section is vital for the zero-tail turning excavators used on restricted urban sites The new boom of the Universal B6? makes it possible to keep the implement 35cm lower than previously while maintaining the same deep and distant digging performance.

  (2) Greater Comfort
1. The clever arrangement of upper structural parts and implement installation position and shape give the operator the equivalent space to that of a small tail turning radius machine.
2. In the canopy spec. model, the partition plate on the operator's right has been removed to eliminate the sense of being hemmed in and broaden the range of vision.
  (3)

Compliance with International Safety Standards

   
1. The canopy spec. structure complies with the ISO and Occupational Health and Safety Law (Japan) standards for TOPS( Tip-Over Protective Structures ) and FOPS (Falling Object Protective Structure). The structure of the cabin spec. model, too, complies with the international standards.
2. Seat belt and rear mirror fitted as standard equipment.
3. Theft-proof electronic key as standard equipment.
