Improved lateral stability is achieved by increasing the

counterweight (

330kg

730lb) and improving the balance of the

machine body.

Lateral Stability      

PC400 - PC400LC

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.

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.

ECONOMY MODE

Operation speed equal to that of the Active mode can be

achieved when handling light duty operation while also

keeping fuel consumption low.

Electronically Controlled High Power Engine Installed

A 246kW (330HP) Komatsu SAA6D125E engine, is the

largest in its class.

High power and low fuel consumption are achieved by

optimizing fuel injection via electronic control.

Maximum Digging Force among the 40-ton Class

With the addition of a one-touch power max. function

(operation time of 8.5 seconds), the digging force has been

further increased.

Maximum arm crowd force (ISO):

198 kN (20.2t)

214 kN (21.8t)

Maximum bucket digging force (ISO):

252 kN (25.7t)

275 kN (28.0t)

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.

force is needed, switch to Power mode for more effective

excavating.

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.
