Leverage Caterpillar connected data and security principles to improve efficiencies, increase productivity and make your business more profitable.
Rear Object Detection for wheel loaders is a two-part system providing enhanced blind spot awareness. Radar provides visual and audible alerts when objects enter a safety proximity zone, while a camera allows the operator to see what's behind the machine when reversing.

Cat® Productivity is a cloud-based application that is scalable to any size operation. Detailed Cat Production Measurement data, machine data and jobsite data are transmitted from the onboard Cat Product Link™ device directly to the web platform, for you to access wherever you are, via your mobile, tablet or desktop device.
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.
View fleet information online with VisionLink and use it to make informed decisions that boost productivity, lower costs, simplify maintenance, and improve safety on your jobsite.
