PRODUCTIVITY FEATURES
High Production and Low
Fuel Consumption
High production and low fuel consumption are achieved through the following two operation modes:
Active mode, with maximum engine output to handle large production, while keeping fuel consumption low; and Eco mode for light duty applications, which enables operation at a speed comparable to Active mode with even lower fuel consumption. The two modes, Active mode for handling “large production” and Eco mode for “low fuel consumption” have been significantly improved.
ACTIVE MODE
This mode handles large production by providing powerful and speedy operation, and achieves economical efficiency by substantial reduction of fuel consumption.

Smooth Loading Operation
Two return hoses
Two return hoses improve hydraulic performance. In the arm out function, a portion of the oil is efficiently returned to the tank.
Two Boom Settings
Smooth mode provides easy operation for gathering blasted rock or scraping down operation. When maximum digging force is needed, switch to Power mode for more effective excavating.
Smooth mode |
Boom floats upward, reducing lifting of machine front. This facilitates gathering blasted rock and scraping down operations.
Power mode |
Boom pushing force is increased, ditch digging and box digging operation on hard ground are improved.
Substantially Improved
Stability
Improved lateral stability is achieved by increasing the
counterweight (330kg 730lb) and improving the balance of the
machine body.
Lateral Stability PC400 - PC400LC 15% better*
*(comparison with current model)
Large Lifting Capacity
PC400-7’s improved lateral stability increases lifting capacity.
Variable Track Gauge (optional)
●Lateral stability is significantly improved when operating with the gauge extended.
●Lateral stability is increased by 30% (compared with the fixed gauge of the current model).
●Complies with transportation regulations by retracting the gauge.
Reduced Revolving Frame Damage
Damage to the revolving frame when going over rocks is
reduced by increasing the clearance between the revolving
frame and track.
clearance:
approx. 200mm (7.9") 30% increased
