Moment limiter for Jib crane, Truck crane( Hydraulic / Crawler crane) . Model Name : SH-7109A - Detection and display of accurate weight value by strain gauged type of load cells - Calcuration of accurate working radius and boom angle by high accuracy of potention meter. - Graphic LCD display of boom angle. Model of SH-7109 is an exclusively designed for moment limiter of Jib cranes. Truck crane(Hydraulic / Crawler crane) and marine cranes.. Moment at the center of crane is changed everytime according to angle of movable boom.. If driver ignore the changed moment and operate the crane with his own will only, this would be a cause of critical situation for safety and turn turtle of crane. Our overload limiter/Moment limiter: SH-7109 detects the real time loads under the hook of crane by means of strain gauge type of load cells and the angle of boom by potention –meter . Working radius is calcurated from angle of boom detected by position-meter and and weight under hook is detected from strain gauge type of load cells. Such a real time weight and data for combined working radius are compared and calcuratd by built-in micom automatically. When the real time weight reach to the limitted weight specified on the micom, warning is given to driver and make the crane stopped. Operator can read present weight, Boom angle, Working radius and limited weight under working condition through display monitor at the cabin and can work in safe. FEATURE * Accurate detection of real time weight by strain gauge type of load cells. Calcuration of working radius through accurate of detection for boom angle by potenion-meter. LCD Display - Display of real time weight (Unit : 0.1Ton ) - Display of boom angle (Graphic LCD type monitor, Display unit: 0.1 degree) - Display of limited weight according to boom angle (Unit :0.1 Ton) - Display of present working radius of crane (Display unit :: 0.1m) - Filttering function against swayness of loading weight. (Prevention of malfunction) - Addition of optional function according to buyer’s request available(anemometer, Hook height etc..) - Easy and simple setting at site.
