Hydraulic forklift scale

Keytroller introduces the Vanguard hydraulic forklift scale designed to provide accuracy to within .2-percent of the rated load. The unit uses a hydraulic bypass manifold module, which is mounted behind the mast on the forklift’s firewall. Hydraulic fluid (under pressure from the load) bypasses through the module where the pressure sensor reads about 150 pressure values in 5 seconds as the load slowly lowers about 20 inches. These pressure readings are averaged by the device and most of the pressure errors are removed or significantly reduced.
