The only on-board scale your rigid truck and PBS combination will ever need

From rigid trucks to multi-combination PBS vehicles — the LM300 CAN Coder delivers accurate, compliant, real-time axle group weighing across every configuration you run. The Loadmass LM300 is a TCA – Approved Smart On-Board Mass (OBM) system designed to keep your fleet compliance with NHVR regulatory requirements and PBS access conditions. With support for air suspension, spring suspension, load cells and mixed sensor applications, it’s the one system that grows with our fleet – rigid trucks, B-doubles, road trains and everything in between.

The LM300 CAN Coder System

The Loadmass LM300 CAN Coder on-board scale system is engineered for operators who run diverse fleets — from single-axle rigid trucks to complex multi-combination PBS vehicles. As a TCA-approved Category B smart OBM system, the LM300 satisfies Australia’s on-board mass compliance requirements, giving you the access conditions you need and the payload confidence your operation demands.

Built for Australian Fleet Operators

Unlike generic weighing systems, the LM300 is purpose-built for the realities of Australian heavy vehicle operations: trailer swapping, combination changes, mixed suspension types, and the precision demanded by PBS accreditation. Its CAN Coder architecture converts analogue sensor signals to digital with four-wire technology that’s immune to moisture and electromagnetic interference — so your readings stay accurate in the toughest conditions.

On-board Weighing. Done Right

Whether you’re running a rigid truck on spring suspension or a seven-axle B-double on air bags, the LM300 gives every axle group its own weight readout in kilograms displayed with programmed vehicle and trailer IDs, in the correct axle order, on a large easy-to-read in-cab display.

PBS & Regulatory Compliance

Performance-Based Standards (PBS) vehicles operate under strict mass and dimension conditions that require verified, real-time on-board weighing. The LM300 CAN Coder is a TCA-approved Category B OBM system — meeting the requirements set by the National Heavy Vehicle Regulator (NHVR) for PBS-approved combinations and Class 2 heavy vehicles seeking concessional mass limits and additional road access.

With the LM300 installed and calibrated, your drivers know exactly what each axle group is carrying before they leave the depot — eliminating the guesswork that leads to overloading breaches, Chain of Responsibility liability, and permit conditions violations.
