OM6004 Optional Equipment - Section 6 Haulpak Payload Meter Page 6-1 PAYLOAD METER GENERAL INFORMATION The Payload Meter digitally displays the weight of the payload in a Haulpak truck in either short tons or metric tons. External deck mounted lights also indicate the payload weight as divided into three stages. A forecast function flashes an external deck mounted light predicting the payload weight after the next bucket of material is dropped into the body. Up to two hundred haul cycles of payload data can be stored in the payload meter’s memory. The stored data is backed up by an internal battery and can be printed out on demand.
The Payload Meter calculates the payload weight by sensing Hydrair suspension pressures and the pitch angle of the truck. A pressure sensor is mounted on each suspension and an inclinometer is mounted in the cab. Logic inputs include a wheel brake lock signal, body up signal, short/metric ton display select and two model select inputs.
