Cat® Upgrade Retrofit Cabs

Cat Upgrade Retrofit Cabs
®
For Large Off-highway Trucks
A lot more cab in a lot less time
How do you keep large off-highway trucks in operation while, at the same time, upgrade their
capabilities? The Cat® Retrofit Cab is a rebuild or replacement option that can help do both by
providing upgrades and cutting installation time. Rebuild time for an outdated cab is normally
measured in weeks, but Cat Retrofit Cabs can be installed in less than a day.
The fully assembled cabs are available for Cat 785, 789 and 793 B and C Series Off-highway
Trucks, with an exterior paint scheme and markings similar to current production cabs. Each
Cat Retrofit Cab includes:
•
•
•
•
•
All new components (including Electronic Control Modules),
ROPS and cab mounting hardware
New, updated wiring harnesses
New Vital Information Management System 4.0 (VIMS)
Cat Comfort Seat with three-point restraint for the operator
Full-size buddy seat
Cat® Upgrade Retrofit Cabs for Large Off-highway Trucks
Maximizing Time and Comfort
Cat Retrofit Cabs offer value by upgrading to newer technologies and assuring ROPS integrity.
The cabs are equipped with VIMS 4.0 for better monitoring of truck operations and payloads.
The “plug and play” design requires less than a day for installation, minimizing downtime. The
Cat Comfort Seat with patented three-point harness improves operator comfort which, industry
studies confirm, can:
•
•
•
•
reduce fatigue
promote safety awareness
improve alertness
have a positive impact on productivity
