Wheel Loader Scale System

How the kit installs on the loader

The standard configuration tees two pressure sensors into the lift cylinder hydraulic lines and adds a position sensor on the boom linkage. The cab-mounted indicator connects with a single wiring loom routed along the existing hose path, so the loader frame is not cut, welded or drilled.

A typical installation takes two to four hours for a trained technician, followed by zero and span calibration with a known reference load. Power comes from the machine 12V or 24V supply, and the indicator housing is rated IP65 for dusty quarry and port environments.

• Two hydraulic pressure sensors on the lift circuit
• Boom position sensor for a defined weighing window
• Cab indicator with bucket, total and target displays
• Optional printer and RS232 data output

What the accuracy figures mean in the field

The indicator itself resolves to 0.02 percent. The figures that matter operationally are the system results: 0.5 to 1.0 percent for a single bucket and about 1.0 percent for totalized loading weight, measured under a controlled lift cycle with a warmed-up machine.

Field results depend on the lift speed window, ground slope, attachment condition and operator routine. The wheel loader scale accuracy guide on this site explains how buyers verify these bands on site and how to run a one-shift field verification before relying on the numbers.

Loader brands the kit can be configured for

The hydraulic sensing route is brand-independent. Configurations are reviewed for wheel loaders and front-end loaders from Caterpillar, Komatsu, Volvo, Doosan, Hitachi, SDLG, XCMG, LiuGong and other major manufacturers, across the 1-10T capacity options listed above.

Send the loader make, model, year and attachment with your inquiry. The hydraulic circuit layout and pressure range are checked against the sensor kit before quotation, so the delivered configuration matches the machine.

Standards context and regulated use

Load cells and indicators in this class are designed with reference to OIML R60 metrological requirements, and the accuracy guide on this site links the current edition of OIML R60 and NIST Handbook 44 for background.

A general product page cannot certify legal-for-trade use. Where a jurisdiction requires approved instruments for transactional weighing, the complete installed system needs the applicable approval and local verification before its readings are used for trade.
