WEIGHT ESTIMATION FOR EXCAVATOR PAYLOADS

摘要

A method for estimating weight of a payload held by load lifting machine (1), wherein the load lifting machine comprises lifting linkage with a boom (5) pivotably connected to a machine chassis (2), the method comprising calculating an estimation using the torque of the boom (5), torque of the boom during calibration lifts for first and second payloads, and dynamic torque adjustment determined for first and second payloads.
