DESCRIPTION:
Payload Meter III (PLMIII) measures, displays and records the weight of material being carried by an offhighway truck. The system generally consists of a payload meter, a gauge display, deck-mounted lights, and sensors. The primary sensors are four suspension pressures and an inclinometer. Other inputs include a body up signal, brake lock signal, and speed. Data Summary 5208 haul cycles can be stored in memory. The following information is recorded for each haul cycle:
- • Payload
- • Operator ID number (0000-9999)
- • Distance traveled loaded and empty
- • The amount of time spent empty run/stop, loading, loaded run/stop, and dumping
- • Maximum speed loaded and empty with time of day
- • Average speed loaded and empty
- • Empty carry-back load
- • Haul-cycle, loading, dumping start time of day.
