LIFTLOG 1000 – INSTALLATION AND CALIBRATION
7
1.3 System Overview
The Liftlog 1000 is a weighing system designed for use principally on counterbalance fork lift trucks. It measures, displays and
records the net or gross weight lifted, normally based on sensing the lift system hydraulic pressure. Normally, a weighing start
point is established by use of a magnetic Reference position sensor fitted on the lift mast. Without the reference sensor
however, the weighing cycle can be started at any lift height (while still allowing the load sufficient height to drop while
weighing).
Triggering the weighing cycle operates a solenoid on a custom, flow-regulated valve, causing the lift cylinder(s) to drop at a
controlled rate while the hydraulic pressure is measured and averaged over the sampling period. The weight is then displayed
either as a gross weight, or if a tare value has been set, then the net weight can be displayed.
