Cat® Inspect allows you to access your equipment data on your mobile device. This easy-to-use app lets you capture inspection data and integrates with your other Cat data systems, so you can keep a close eye on your fleet. More than one million inspections are completed each year, providing convenience and accountability to equipment owners.
The Cat PL161 Attachment Locator is the most advanced OEM integrated solution for attachment tracking. The PL161 mounts easily to your attachments or anything else you want to track.
Cat® Product Link™ wirelessly connects you to your equipment giving you valuable insight into how your machine or fleet is performing. Information such as location, hours, fuel usage, productivity, idle time, and diagnostic codes are made available through online web applications so that you can make timely, fact-based decisions to maximize efficiency, improve productivity, and lower the cost of owning and operating your fleet. Available with satellite or cellular connectivity.
Remote Flash sends an alert from your Cat dealer, prompting you to update the software on your machine. To minimize downtime, updates can be deployed while on the jobsite without having to wait for a dealer technician to arrive. Remote flash decreases maintenance time and keeps your asset running with maximum efficiency.
Remote Troubleshoot allows your Cat dealer to run testing while the machine is operating. Once the problem is identified, a technician can fix it with the correct parts and tools the first time, saving time and money. Remote Troubleshoot decreases maintenance time and keeps your machine running with maximum efficiency.
