Lattice Boom Crane Structural Design Validation using NI CompactDAQ Our customer needed to validate several new con?gurations (di?erent boom and jib lengths) of its heavy lift lattice boom crane. To comply with SAE J987 design criteria standards, various sections and members of the crane’s lattice boom and jib had to be instrumented with strain gauges and tested under various loads. For this validation, we needed a system that could acquire data from 144 quarter bridge, 350 ohm strain gauges at the same time. The system also had to be distributed because the strain gauges were spread out along the length of the 300-ft boom and jib. Because the crane testing was outdoors, all instrumentation, hardware, and cabling had to be properly sealed and environmentally protected during the entire mul
