On-board weighing on forklifttrucks
Feature A. Hydraulic weighing system B-1. Weighing carriage, permanent B-2. Weighing carriage, ‘Quick-Tach’ C. Weighing forks
Measuring principle static: forklift and forks must stand still forks and forklift stand still forks and forklift stand still forks and forklift stand still
Accuracy 1 - 2 % 0,2% 0,2% 0,2%
Can be stamped? no no yes, OIML class III (0,1%) up to FEM III - 5 tons yes, OIML class III (0,1%) up to FEM II - 2,5 tons
Min/max weight per weighing 500 / 40.000 kg 50 / 15.000 kg 50 / 15.000 kg 50 / 3000 kg
Installation easy on each forklift truck, on each type of lift carriage less easy,
in your workshop
easy on each forklift with standard fork carriage up to ISO/FEM IV easy on each forklift with standard fork carriage up to ISO/FEM II and III up to 3000 kg
Front attachment any any except integrated side shifters any only with side shifters and some fork positioners
Harsh working conditions insensitive good good medium
A. Check weighing by measuring the hydraulic pressure to the lift cylinders at a certain fork height:
Static measurement at standstill: forks are lifted to a certain height where the pressure is measured and weight displayed after about 2 seconds;
The height is detected by an inductive switch;
From 500 to 40.000 kg;
Standard accuracy : average 1% on 10 weights, 2% on an individual weight.
B. Add a weighing carriage with 4 weigh bars between the lift carriage and the forks or front attachment:
From 100 to 10.000 kg,
Standard accuracy: 0,2%,
Can be trade approved in class OIML III with fork carriage FEM/ISO 2 and 3,
Permanent signal: weight is displayed at any fork height; forks can be (un)loaded and display shows actual weight which can be useful to mix several components,
Very strong and reliable, even in harsh conditions as foundries and wet applications.

2 ways to install:
Weegbord, permanente montage B-1. permanent: we drill 4 holes in your fork carriage to fix the weigh bars into.

Benefit: small own thickness and weight, hence more residual lifting capacity of your forklift truck.
Weegbord, QuickTach B-2. ’Quick-Tach’: the 4 weigh bars are located between 2 strong carriages. The rear one is easily hung at your lift carriage or integrated sideshift, the front one takes the standard forks or any front attachment like a rotator, clamp, bucket, ...

Benefit: easy installation on any standard fork carriage, also slim line carriage.
C. Weighing forks instead of standard forks Weighing forks 
for reach-trucks, warehousing trucks and carefully driven counterbalanced trucks,
Digital indicator:
+ installed in the cabin, readable at any fork height,
+ integrated in the left fork with a rechargeable battery: easy installation and transfer to any other truck.
Rated capacity up to 3.000 kg,
With fork carriages FEM/ISO 2 and 3,
Fork section is only slightly wider and higher as on a standard fork,
Standard accuracy: 0,2%

Digital microprocessors withWeighing forks LTF with integrated display
25 mm high digits backlit,
Strong enclosures IP65,
Many models to suit your needs:
- simple indication the actual weight,
- summing up consecutive weighings,
- tare by weighing or by arrow keys or numerical keyboard,
- ad an ID number to be printed or transferred,
- alarm when a target weight is reached while filling or while emptying,
- mix several components while filling or while emptying,
- output to printer on paper coil or slips or tags,
- 2 display with small or large figures, to be read from the forks side,
- transfer weighing data to PC by contactless chip cards or handheld terminals
- Atex-protection,…

Electrical supply to the weighing system by the forklift, straight up to 24 Volts or through a voltage converter.
Types B and C: transfer the signal between weighing carriage or forks to the microprocessor via:
- coil cable along the mast: easy installation and replacement.
- straight cable inside a rubber hose with steel wire reinforcement, parallel to the lifting chains.
- wireless radio transfer between the weighing carriage and the indicator.
On-board weighing on stackers
Weighing forks on stackers
Straddle fork stackers with standard forks can be equipped with systems A, B1, B2 and C.

Stackers with forks over the legs can be easily equipped with type A.
When a higher accuracy is requested, we can transform your fork carriage to fit weigh bars inside. Fork height is increased by 5 mm, fork width mostly by 20 mm.
