TWG Launches the Guardian Wireless RCI System for the Crane Industry

DOWNERS GROVE, Ill., Oct. 16, 2025 /PRNewswire/ -- TWG, part of Dover (NYSE: DOV), today announced the launch of the Guardian™ Wireless Rated Capacity Indicator (RCI) System, an advanced operator aid for cranes that monitors load and helps alert operators when the machine is approaching its maximum operating capacity. Developed by TWG's Greer Company® brand, Guardian delivers accuracy and innovative, industry-first features that provide real-time feedback to help crane operators work more safely and productively.

"We are excited to introduce the new industry standard in RCI systems," said Jason VanderMeer, General Manager of TWG. "We designed every aspect of Guardian to be best in class, from the wireless technology, user interface, calibration, installation, display, system architecture, and even the batteries. The system is easy to use for operators while offering industry-leading display and accuracy capabilities."

Among Guardian's many features are wireless nodes that feature a patent-pending, maintenance-free, solar rechargeable battery system with standard AA batteries for backup. The wireless load links are pre-calibrated within 0.1% accuracy and use standard AA lithium batteries that last up to 10 months of operation and up to 8 years in standby mode.

Guardian also utilizes an open system architecture that allows reuse of cable reels and ATB switches, enabling fast, easy installation without the need for external relay or fuse wiring.

"Another feature we're very proud of is the Guardian display," VanderMeer added. "It raises the bar with a modern interface that uses clear, easy-to-understand graphics for at-a-glance monitoring and safer crane operation."

The high-contrast, bonded 7-inch LCD display mitigates operator blind spots and supports all-day visibility, even in direct sunlight while wearing polarized glasses. It also supports glove-touch operation and offers a wide 170-degree viewing angle.
