  • Page 7: Introduction

    The Loadrite Weighing System measures the weight of loads lifted by front- end loaders, log loaders, forklift trucks and similar machines that use hydraulic rams to lift the load. The Loadrite is installed in the cab of the loading machine and is connected to sensors on the lifting arms.

  • Page 8: Indicator Lights

    LOADRITE PRO OPERATING MANUAL The Loadrite has internal memory which stores settings and production data even when switched off.

    Switching On The Loadrite powers up automatically when you switch on the ignition of the loading machine. If the Loadrite has been switched off for more than 1 hour, it displays the Warm Up screen when powered up. Standby The Loadrite has a ‘standby’ mode which is similar to turning the Loadrite off.

  • Page 12: The Ready Screen

    The short total is simply the sum of loads since you last cleared the total. When the Ready screen is displayed, the Loadrite is in Total mode and is ready to weigh. Note that Sand in the below example represents the current product of choice.

  • Page 13: Static Weigh Function

    The trigger point is where the metal plate passes the body of the trigger. Static Weigh function The Loadrite has an option known as ‘Static Weigh’. When this is used, the weight display is always ‘live’ and no trigger is used.
