Load Systems International Inc.’s load moment indicator (LMI) for hydraulic cranes features a pair of pressure transducers that read the rod and bore side pressures of the lift cylinders. Data from the transducers is transmitted wirelessly to the GS820 display.
The typical error rate seen by the system is 1% of maximum load capacity. The GS820 features a large sunlight readable graphical display, onboard data logger and the ability to upload load charts via the onboard USB port or download the data logger via USB thumb drive. The display shows the following data a glance: all crane geometry, working load limit, actual load, selected chart/counterweights, wind speed, alarms and system faults.
