ACTIVE MODE
This mode handles large production by providing powerful and speedy operation, and achieves economic 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)

Comfortable Cab
The New PC400-7’s cab volume is increased by 14%, offering an exceptionally comfortable operating environment. The large cab enables full flat reclining of the seat back with headrest.
Pressurized Cab
The optional air conditioner, air filter and a higher internal air pressure (6.0 mm Aq 0.2″ in Aq) prevent external dust from entering the cab.
Low Noise Design
Noise level is remarkably reduced, not only engine noise but also swing and hydraulic relief noise. Low Vibration with Cab Damper Mounting PC400-7 uses a new, improved cab damper mount system that incorporates longer stroke and the addition of a spring.
The new cab damper mounting combined with a strengthened left and right side deck aids vibration reduction at the operator’s seat.
Vibration at floor is reduced from 120 dB (VL) to 115 dB (VL).
