Built Tough for Western Star – Precision Weighing for Kiwi Roads

Western Star trucks are renowned across New Zealand for their rugged build, powerful performance, and custom spec options—favoured in industries like logging, mining, construction, and long-haul transport. With heavy payloads and varied terrain, ensuring axle group compliance is essential under NZTA regulations.

Loadsense provides a smart, NZ-compliant onboard Western Star Truck weighing system that’s specifically designed to suit Western Star models operating in New Zealand, delivering accurate axle group weights across all suspension types—air bag or mechanical spring—and for all trailer combinations.


Why Axle Group Weighing Matters in New Zealand

New Zealand’s Vehicle Dimensions and Mass (VDAM) Rule and roadside enforcement via Weigh-in-Motion (WIM) make it essential for Western Star operators to know not just gross weight, but individual axle group weights.

Consequences of non-compliance include:

  • Instant fines from WIM sensors

  • Permit breaches for 50MAX and HPMV routes

  • Inaccurate RUC charges and increased operating costs

  • Downtime due to roadside inspection or reloading

Loadsense eliminates guesswork by giving operators live axle group weights in real-time, helping you load efficiently while staying legal.


Compatible with All Western Star Suspension Types

Western Star trucks in NZ vary from long-haul highway specs to rugged off-road applications. Loadsense supports both air suspension and mechanical spring suspension, with dedicated sensor systems for each.


✅ Air Bag Suspension – Pressure Sensor System

Common on:

  • Western Star 49X and 47X highway models

  • Heavy haul and B-train freight units

  • Livestock and logging trailers with air suspension

Loadsense pressure sensors tie into the air suspension system to measure air pressure changes and convert them into live axle weight data.

Key Benefits:

  • Highly accurate on sealed and level terrain

  • Compatible with cab display or Bluetooth app

  • Quick calibration without weighbridge visits

  • Perfect for payload optimisation on long-haul freight


✅ Mechanical Spring Suspension – Axle Deflection Sensors

Used on:

  • Western Star vocational or off-road configurations

  • Logging, quarry, and rural construction trucks

  • Older fleets running spring-based suspensions

Loadsense axle deflection sensors are designed to measure spring movement under load—ideal for rough NZ conditions like forestry tracks and gravel roads.

Key Benefits:

  • Rugged and water-resistant design

  • Performs well off-road and on uneven ground

  • No major modifications needed

  • Long-lasting, low-maintenance performance


Full Truck and Trailer Weighing Integration

Whether your Western Star is towing a:

  • 4-axle dog trailer

  • B-train or semi

  • Tipper, flat deck, or log trailer

Loadsense can integrate axle group sensors across both the truck and trailer, giving you a complete picture of your total load and axle weights.

This system supports mixed suspension setups (e.g. air on the truck, spring on the trailer) and keeps your whole rig within legal limits.


NZTA Compliance Without the Guesswork

Loadsense is purpose-built for New Zealand’s roads and rules, helping Western Star truck operators stay on top of:

  • VDAM axle group limits

  • 50MAX and HPMV permit conditions

  • Weigh-in-Motion detection zones

  • Accurate RUC calculations

  • Safe, consistent payload optimisation

Whether you’re hauling logs in the King Country, carting aggregates in Canterbury, or crossing the Cook Strait with freight, Loadsense gives you the control and confidence to meet legal load limits.
