TWG Introduces the Guardian Wireless Rated Capacity Indicator System

On October 16, 2025, TWG, part of Dover, announced the arrival of the Guardian™ Wireless Rated Capacity Indicator (RCI) System, a pioneering operator aid meticulously crafted for cranes. This advanced technological solution aims to monitor load and provides crucial alerts to operators when nearing maximum operational capacity. Designed through the expertise of TWG's Greer Company® brand, Guardian not only boasts unparalleled accuracy but also includes innovative industry-first features that deliver real-time insights, thereby enhancing the safety and productivity of crane operators.

Jason VanderMeer, General Manager of TWG, expressed enthusiasm over launching what they consider the new benchmark in RCI systems. According to VanderMeer, each component of Guardian has been designed to lead the industry, encompassing top-tier wireless technology, intuitive user interfaces, efficient calibration, streamlined installation processes, vibrant display capabilities, and even superior battery systems.

One of the standout elements of the Guardian system is its wireless nodes, which feature a groundbreaking, maintenance-free, solar rechargeable battery system, supplemented by standard AA batteries for backup. These wireless load links come pre-calibrated to a remarkable accuracy of 0.1%, utilizing standard AA lithium batteries that can sustain up to 10 months of ongoing operations, and an impressive eight years in standby mode. This ingenuity not only ensures reliability but also minimizes operational interruptions due to battery failure.

The Guardian system is engineered with an open system architecture, allowing for the reuse of existing cable reels and ATB switches. This design ensures a fast and straightforward installation process, eliminating the need for cumbersome external relay or fuse wiring. “One of our proudest achievements is the Guardian display,” VanderMeer elaborated. “It elevates standards with a contemporary interface featuring clear graphics that allow for quick monitoring and safer crane operation.”

The high-contrast, bonded 7-inch LCD display is designed to reduce operator blind spots and maximizes visibility throughout the day—even in direct sunlight and while wearing polarized glasses. It uniquely supports glove-touch operation and provides a wide 170-degree viewing angle, facilitating convenient operation from varied positions.

TWG's commitment to quality and innovation in the crane industry is underlined by its extensive expertise in manufacturing robust equipment, including winches, hoists, hydraulic pump drives, and electronic monitoring systems. They have a diverse portfolio that spans seven model lines, and with over one million units installed, they establish a strong safety standard across the sector.

This launch not only reinforces TWG's position as an industry leader but also emphasizes their dedication to advancing crane safety technology. For industry professionals seeking reliable equipment that maximizes safety and operational efficiency, the new Guardian Wireless RCI System emerges as a groundbreaking solution amid growing demands for enhanced safety in crane operations.
