CARGO WEIGHING GEAR Russian patent published in 1998 - IPC

FIELD: lifting and transportation engineering. SUBSTANCE: cargo weighing ear is designed to weigh cargoes on crane, platform and other scales. Gear incorporates force-measuring transmitters of weight load installed in cargo transporting mechanism, amplification and conversion unit electrically coupled to transmitters, light panel displaying weight loads. Gear is also fitted with temperature-sensitive elements installed in force-measuring transmitters and screening enclosure where amplification and conversion unit made in the form of programmable controller with adding device is mounted with clearance. Enclosure also houses fan and controller has heater and temperature-sensitive resistor electrically coupled to heater and fan. Controller is electrically coupled independently to each temperature-sensitive element and to each force-measuring transmitter. EFFECT: enhanced reliability and accuracy of gear, expanded field of its application. 1 dwg
