For those in the construction industry, you know exactly how critical boom length data is to lifting safety. This reel box is purpose-built as an “electronic measuring tape” for cranes, aerial work platforms, and other heavy equipment. Mounted at the base of the boom, it uses a wear-resistant steel cable and precision sensor to transmit real-time boom extension data directly to the load moment limiter, eliminating overload risks from the source. The housing is formed from heavy-duty
