2 Introduction
The Loadrite Force 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.
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.

3 Quick Start Guide
This section summarises the common Loadrite procedures. For full details
of weighing methods, see Weighing Overview on page 10 and Weighing
Procedures on page 12.
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.
To put the Loadrite into standby press and
hold , the EXIT key, when in the
Ready mode.
To restart the Loadrite, press any key.

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 for
over an hour.
Raise the empty bucket or forks past the
trigger point three times. Warm up

The Loadrite beeps at each lift and
displays the count down from 3. After the
third lift, the Ready screen is displayed
and the screen may look like this.
If it is time to check zero, the Loadrite will
display the Check Zero message to
remind you.
More information about Ready screen and
Check Zero screen will be covered later
in this manual.

The Ready screen shows the product name and the short total for that
product. The short total is simply the sum of loads since you last cleared
the total.

Zeroing
It is required to zero the Loadrite from time to time. This is to avoid
inaccurate readings due to build up of material in the bucket.

4 Weighing Overview
Weighing Modes
While individual bucket weight can be measured, the Loadrite also has an
ability to accumulate how much weight you have loaded on to a truck. The
main weighing modes are shown in the following table. The modes that are
available in a particular Loadrite depend on the installation.
Mode Description
Total As you add bucket loads, the weights are added to the totals.
The short total is displayed.
Target A target weight is entered into the Loadrite. As you add bucket
loads, the remaining value to reach the target is displayed.
The normal mode of operation is Total mode, which uses the Ready
screen. To return to Total mode from Target mode, press and hold
.
Short and Long Totals
The Loadrite keeps a total of the bucket weights that you add, of which two
independent totals are stored.
Short Total Typically used to display the total weight lifted
onto a truck.
As you add successive loads, the Loadrite
displays the updated Short Total (sum of the
loads so far) on the Ready screen.
Long Total Typically used to accumulate the weights lifted
over a longer period, for example a shift or a
day.
Long Total may be viewed via the menu.
(See page 18.)
Accurate Weighing
For accurate weighing, make sure that:
• The bucket or forks are fully rolled back for each lift.

LOADRITE FORCE OPERATING MANUAL
11
• The loader is stationary (for best accuracy).
• The lift arms start well below the trigger point (see note on page 7). This
ensures that all acceleration and load bounce has been eliminated well
before the weighing sequence begins.
• The Loadrite is correctly zeroed. (Zeroing is described on page 14).
General Method of Weighing
1. BUCKET BACK. After picking up material into the bucket, roll the
bucket back.
2. LIFT. Raise the load smoothly past the trigger point using normal
engine revs. (The trigger point is where the metal plate passes the
body of the trigger). For best results, operate the lift lever before
accelerating the engine so that the machine does not rock as it lifts.
The Loadrite beeps, turns the TRIG light on and displays the load.
(See also page 6).
3. ADD. The Loadrite waits for a few seconds for you to take one of the
following actions:
• Press to add the weight to the long and short totals, or
• Press to subtract the load from the totals, or
• Press to zero the measuring system.
If you don’t press a key, the Loadrite beeps and prompts you to take
action. The Loadrite then counts down and if you still don't press a
key, it discards the weight and goes back to the Ready state.

The Loadrite has an option to use a remote add button. If fitted, the remote
add button is normally mounted on the lift lever. The remote add button can
be used instead of / as well as the add button on the keyboard.

In Target mode, the display is different. For details, see Target Mode on
page 21.
Auto Add
Auto Add is an optional feature that is selected during installation. If Auto
Add is enabled, the Loadrite can automatically operate the ADD function
every time a load is lifted past the trigger point.
The Auto Add indicator light illuminates
when the Loadrite is in Auto-Add mode. Ready
02:40PM

To turn on/off auto add function
1. Press twice to access user menu.
2. Use to scroll to Auto Add.
3. Press to select.
4. Use to adjust the setting.
5. Press to accept the setting.
If Auto Add is on:
• The procedure for zeroing is different. See page 16.
Subtracting a Load
This function can be useful when only part of a final bucket load of loose
material is required. You can add the full bucket load and then re-weigh
and subtract the amount remaining in the bucket.
Another example is when a log has been added and then removed from a
truck.

In Target mode, the display is different. For details, see Target Mode on
page 21.
Zeroing
When you raise an empty bucket past the trigger point, the display should
read zero. However, due to build up of material in the bucket, a small zero
error may occur.
Zero error affects the accuracy of lifted weights.
