Portable Axle Weighing Scale Solution: GPWA08 for Vehicle Weight Enforcement
Key Takeaway
• GPWA08 supports up to 320t axle load with static accuracy of 0.1-0.3% FS
• Aviation aluminum alloy pads with built-in shear beam load cells for waterproof, durable field operation
• Dual measurement modes: dynamic (5 km/h pass-through) and static (full-wheel placement)
• Integrated thermal printer + wireless/wired communication for instant on-site weight tickets
Portable axle weighing scales have become indispensable tools across transportation, logistics, construction, and regulatory enforcement. The GPWA08 Portable Axle Weighing Scale from GALOCE delivers high-precision vehicle weight measurement in a mobile, field-deployable format, eliminating the need for permanent weighbridge infrastructure.
Why Portable Axle Weighing Matters
Overloaded vehicles cause road damage, bridge structural degradation, increased braking distances, and costly regulatory fines. Portable axle weighing scales address these risks by enabling on-site weight verification at any location, without requiring vehicles to detour to fixed weigh stations.

GPWA08 System Architecture
The GPWA08 system consists of two core components: weighing plates (pads) and a handheld indicator. Each pad incorporates multiple high-accuracy shear beam load cell sensors embedded in a high-strength aviation aluminum alloy housing. The indicator processes signals, displays readings, and prints weight tickets on-site.

Installation & Setup Guide
Setting up the GPWA08 portable axle weighing system is straightforward and can be completed in minutes:
Step 1: Select a flat, solid surface (concrete or compacted asphalt) free of debris and loose material.
Step 2: Position the weighing pads side by side, matching the vehicle track width. Ensure pads are level.
Step 3: Connect the signal cables (wired mode) or power on the wireless modules (wireless mode).
Step 4: Power on the handheld indicator and verify signal reception from all connected pads.
Step 5: Select measurement mode (dynamic or static) on the indicator. For dynamic mode, set the vehicle speed limit to 5 km/h.
Step 6: Direct the vehicle over (dynamic) or onto (static) the pads. The indicator displays wheel load, axle load, and total weight. Press print to generate a weight ticket.
For wireless mode, maintain a clear line of sight between pads and indicator within 20-30 meters. For wired mode, route the high-strength cable with protective spring to prevent damage from vehicle overrun.

FAQ
Q: What is the maximum vehicle weight the GPWA08 can measure?
The GPWA08 supports axle loads up to 320t. Total vehicle weight depends on the number of axles. For example, a 5-axle semi-trailer with each axle under 320t can be fully weighed.
Q: What is the difference between dynamic and static accuracy?
Static measurement achieves 0.1-0.3% FS accuracy since the vehicle is fully stopped on the pads. Dynamic measurement typically achieves 0.5-1% FS because the vehicle is moving at 5 km/h, introducing slight measurement variance from suspension dynamics.
Q: How many weighing pads do I need?
For dynamic measurement, only 2 pads are needed (one per side of the vehicle). For static measurement, you need one pad per wheel position. The GPWA08 supports configurations from 1-to-4 (2-axle vehicles) up to 1-to-16 (multi-axle heavy haulers).
Q: Can the GPWA08 operate in rainy or dusty conditions?
Yes. The shear beam load cells inside each pad feature waterproof sealing, and the aviation aluminum housing provides excellent corrosion resistance. The system is designed for outdoor field operation in harsh environments including rain, dust, and extreme temperatures.
Q: What information does the printed weight ticket include?
The built-in thermal printer outputs: date/time, each wheel load, each axle load, total vehicle weight, approved load capacity, and overload weight (if applicable). This provides complete documentation for regulatory compliance and fleet management.
