Large Comfortable Cab
Comfortable Cab
New PC1250-8R's cab offers 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
PC1250-8R 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.
