Two decades of heavy vehicle mass compliance expertise.
IMA Compliance Pty Ltd specialises in on-site heavy vehicle weighing and compliance assessments — with a particular focus on GVM, axle group loading, NHVR mass compliance, and Chain of Responsibility obligations.
We bring the same portable weighing systems used by NHVR inspectors directly to your depot or worksite, providing immediate, accurate assessment of both gross vehicle mass and individual axle group weights.
Beyond weighing, we help operators understand the operational risks behind their loading practices and build practical compliance strategies that keep fleets profitable and on the right side of the law.
Inspect. Manage. Act.
A clear three-step methodology built over twenty years of fleet assessments.
Inspect
We arrive on-site with NHVR-grade portable weighing systems. Every vehicle is weighed at gross and axle-group level — no off-site trips, no operational disruption.
Manage
We analyse the data: mass centres, axle effects, loading risks, and gaps against NHVR mass compliance and CoR obligations. You get clarity on where your fleet stands.
Act
We deliver practical strategies — from load space redesign and driver awareness, through to CoR documentation and ongoing compliance planning. You move forward with confidence.
