Dump truck tip-over safety device |
摘要 |
<p>A tip-over safety device, for a dump truck comprising a bed (3) and hoist cylinders (5), comprises a loaded weight estimation unit (32) that estimates the load weight upon the bed; a chassis moment of rotation computation unit (33) that computes the moment of rotation of the chassis (Mb) that arises from the movement of the load when the load is ejected; a reference moment computation unit (34) that assigns moment of rotation that is less than or equal to the tip-over threshold moment (MI), which is the smallest moment of rotation required to lift the front wheels (1) off the ground, to the reference moment (Ms); a determination unit (35) that determines whether the moment of rotation of the chassis (Mb) exceeds the reference moment (Ms); and a display device (37) that notifies the driver that there is a strong probability of a tip-over, if it is determined that the moment of rotation of the chassis (Mb) has exceeded the reference moment (Ms). It is thus possible to avoid dump trucks tipping over as a result of dumping their loads all at once.</p> |
