The 303.5 CR’s more dynamic design with quick transient speeds helps to reposition the excavator in a shorter period, limiting the time the machine is not working. This results in contractors being up to 35% more productive at the jobsite, depending on application and conditions.
The update is compatible with all next generation builds dating back to the first production models in 2021. The current software version is available on the excavator’s operating monitor, and customers can get the latest update from their Cat dealer.
Key features of the 303.5 CR include:
- Heavy lifting and performance
- Capable of lifting, swinging and carrying a standard 2,450 lb (1111 kg) street plate.
- Trenching productivity and controllability of the angle blade in Stick Steer mode.
- Comfort and industry-first features
- Sealed and pressurized operating cab with adjustable operator settings.
- Exclusive Cat Stick Steer joystick control to enhance machine travel and cruise control.
- Simplified service
- Easily accessible checkpoints from ground level and a unique tilt-up cab/canopy to reach additional service areas.
- Compact radius swing
- Reduces overhang when working to the side, allowing machines to deliver high performance in confined spaces.
The updates will be installed on the Cat 303.5 CR at the Utility Exposition, October 7-9, and Equip Exposition, October 21-24, in Louisville, Ky. and are available to operate.
