Comfortable Cab
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).
dB (VL) is index for expressing
size of vibration.
