Excavators - Komatsu Excavators
- PC128UU-2
Features :- Komatsu Excavators
- PC128UU-2
Hydraulics - The PC128UU features the same HydrauMind hydraulic system found on all other Avance Dash 6 excavators for greater control and smoother operation.
Cab Design - A larger cab (43% in volume over the UU-1) allows the operator to work longer with less fatigue. AM/FM radio, air conditioner, and heater are now standard equipment for greater operator comfort and convenience.
The sliding convex door facilitates entrance in confined work areas and reduces the danger of being damaged on roadways because the door does not protrude when open.
Automatic Height and Depth Stop - Automatic stops are ideal for working in confined areas such as overhead or buried power lines,or restricted work areas.
Auto Attachment Safety Stop - Allows the operator to focus on maximum attachment speed without concern of hitting the machine body.
Protected Hydraulics - To avoid damage attachment hoses are located inside the boom and the cylinder has a guard.
Standard Dozer Blade - The dozer blade allows easy backfill.
