Manitowoc’s new upFLEX Rated Capacity Limiter (RCL), first presented at CONEXPO-CON/AGG 2026, has officially been launched to market. It’s an improved version of the iFLEX RCL units featured on Grove rough-terrain and truck cranes built between 2002 and 2023.
upFLEX replaces iFLEX RCL with a sleek new look and standardized controls
With upFLEX, owners of older Grove mobile cranes can update to the latest lift management technology, and Manitowoc estimates roughly 13,000 machines could be eligible for upgrade.
upFLEX features a sleek, modern design with a 7-inch console and intuitive controls that enable the operator to cycle through working screens and operating modes. The system works across a full range of Grove rough terrain and truck cranes previously covered by older iFLEX models.
A simple, plug-and-play option for crane operators
This standardization brings consistency and efficiency to operators’ work. Installation is simplified, too, with the RCL connecting directly to the crane’s CAN-BUS via the on-board Ethernet. The system is truly plug-and-play, reducing installation hassle and benefiting operators by providing the same look and feel in an upgraded system.
“We’re excited to bring the upFLEX RCL to market. We got lots of interest from visitors when we introduced the unit at CONEXPO 2026, and we know customers want to extend the life of their proven and capable Grove cranes — upgrading with upFLEX is a great way to do that. The plug-and-play design allows owners to harness the latest load management technology in a fast and straightforward way,” said Matt Wong, vice president of customer support at Manitowoc.
The new upFLEX RCL replaces the iFLEX5 (LI5G), iFLEX5 (CGMK), and iFLEX2 (LSQG).
