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).
