(Image by Caterpillar) IRVING, TX.– The next-generation compact radius Cat 303.5 CR Mini Hydraulic Excavator features a significant software update designed to improve transient speeds up to 25 per cent compared to previous 303.5 CR next-gen models, states Caterpillar (Cat).
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. According to Cat, this results in contractors being up to 35 per cent 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
