EXCAVATORS WITH A TELESCOPIC ARM

(UPPER ARM SLIDING TYPE)

• The hydraulic system allows for rapid arm movement, maximizing work efficiency.
• Roller-based sliding minimizes vibration and wear, extending the arm’s service life.
• The arm’s reach rivals that of much larger excavators, ideal for confined areas needing wide coverage.
• Simplifies slope-finishing tasks.
