1 Introduction
The Loadrite Weighing System measures the weight of loads lifted by small
front-end 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.
As the machine raises the load, the Loadrite measures the hydraulic
pressure in the lift cylinders, converts pressure into a weight reading and
displays the result. An electronic trigger device mounted on the lift arms
ensures that the pressure readings are always taken at the same position
on every lift.
The weight of the bucket or forks and associated structures is zeroed out
when the system is calibrated so that only the weight of the payload is
displayed. While operating the loader, the driver can add each weight lifted
to a running total.

Auto-Add Illuminates when the Loadrite is in Auto-Add
mode. In this mode, the Loadrite will
automatically add the lifted weight.

2 Quick Start Guide
This section summarises the common Loadrite procedures. For full details
of weighing methods, see Chapter 3 Weighing Overview on page 9 and
Chapter 4 Weighing Procedures on page 11
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 30 minutes, it displays
the Warm Up screen when powered up.
Standby
The Loadrite has a ‘standby’ mode which is similar to turning the Loadrite
off.
To put the Loadrite into standby press
, the EXIT key, when in the Ready
mode.
To restart the Loadrite, press any key.
Standby
The Warm Up Screen
For best weighing accuracy, the hydraulic fluid in the lift cylinders should be
at normal operating temperature. This is achieved by raising and lowering
the empty bucket or forks a few times.
The Warm up screen is displayed if the machine has been turned off over
an hour.
Raise the empty bucket or forks
past the trigger point three times. Warm up
