Abstract
A hydraulic lifting device, such as a forklift, is provided and is capable of dynamically measuring the weight of a load being lifted. A plurality of pressure measurements are taken during the lift for a period of time, which are stored in memory. A computer program is operated on by a microprocessor to process the pressure measurements to filter unwanted signals associated with vibration and other mechanical disturbances. The pressure samples processed by the computer program correspond to a portion of the lift during which acceleration of the forks has ceased, allowing a closer correspondence between the weight lifted and the pressure of the hydraulic fluid sensed.
