RMT Introduces In-Motion Grapple Scale System

RMT Equipment has introduced the RMT-XW in-motion grapple scale system that combines wireless data communication and control with a new load-sensing technology.

Marc Lefebvre, RMT Equipment’s North American sales manager, says that the RMT-XW system improves the accuracy of load measurements to within 0 ± 3 percent of true weight, while reducing installation and setup time to as little as two hours.

“The fact is, this scale requires no configuration time at all,” Lefebvre says. “Installation is as simple as replacing the grapple’s attachment link with our weigh link, extend current hydraulic lines, then mounting the remote display in the cab. That’s it!”

The wireless design also ensures higher reliability in severe-duty applications by eliminating extra electrical connections from the weighing link to the in-cab monitor.

The new scale is self-contained within a weigh link that replaces the yoke or link of the grapple attachment. A weigh chamber in the link integrates the high resolution load cell and motion controller, including a wireless antenna and battery pack.

RMT is currently conducting trials to confirm that the same weigh link used in the grapple scale can be used for in-motion weighing with lifting magnets.

According to Lefebvre, by ensuring accurate, maximum weights as trucks are loaded, drivers will have no need to re-weigh at the gate and return to the loading area to adjust their loads. Data accumulated and transferred from the RMT XW units gives operations managers an easy tool to compare productivity levels for varied types, sizes and makes of equipment, or to identify potential training needs of their operators.

The RMT-XW system is supplied complete with its own Windows-compatible data logger, USB data connection, optional reporting software and printer. The system gauges each load automatically without requiring operator intervention and accumulates data continuously to allow flexible reporting and analysis. Its data can be exported directly into standard spreadsheet formats, so load information can be shared readily with other corporate systems and business applications.

Maintenance of the scale is simple, requiring only monthly greasing of the weigh link. The data logger’s battery can be changed quickly with no recalibration required.

The system is offered in a range of models to suit different equipment and applications. Models equipped with 10-ton, 15-ton and 20-ton load cells are offered for conventional loaders, scrap handlers and excavators. Smaller units with 5-ton and 7-ton load cells are recommended for small material handlers, excavators, loaders and forklifts.
