Intercomp Portable Weigh-In-Motion (WIM) Scale Systems
Intercomp's portable Weigh-In-Motion (WIM) weighing systems represent the latest technology for the fast, accurate, non-intrusive determination of vehicle axle and gross weights. These systems are ideal for roadside enforcement, monitoring compliance with weight limits, and for applications where fast data acquisition and flexibility are paramount.
Portable WIM solutions enable authorities to weigh vehicles while in motion, with minimal traffic interruption, significantly increasing inspection efficiency.
Main Product Lines and Applications
Intercomp offers a wide range of portable WIM solutions that can be adapted to different performance requirements and deployment environments.
1. LS788-WIM™ Portable Weigh-In-Motion Scale
This model offers a combination of portability and high accuracy, designed specifically for rapid field deployment.
Main Features:
- Portability: Easy to install and remove, ideal for mobile inspection points.
- WIM Capability: Capable of measuring axle load while in motion, considering the vehicle's speed.
- Application Areas: Highway traffic enforcement inspections, enforcing temporary weight restrictions.
2. LS630-WIM™ Portable Low-Speed Weigh-In-Motion Scale
The LS630-WIM™ system is designed to provide extremely accurate measurements even at low speeds (slow movement), often used in locations where vehicles must slow down for safe passage.
Main Features:
- Low-Speed Accuracy: Optimized for slow driving speeds, where results close to static weighing can be achieved.
- Robust Construction: Resists wear and tear caused by heavy traffic and varying environmental conditions.
- Integration: Seamlessly integrates with existing data acquisition and signaling systems.
Technical Specifications and System Components
Intercomp WIM systems ensure reliable performance according to the highest industry standards. Although exact specifications are model-dependent (LS788-WIM, LS630-WIM), the general system components and performance characteristics are as follows:

Main Components of the System
Portable WIM systems generally consist of the following components, which together ensure comprehensive measurement:
- Sensor Pads/Sensor Strips: These extremely durable, low-profile elements are placed in the vehicle's path. Measurement occurs based on the deformation or pressure change occurring due to the vehicle's weight.
- Signal and Speed Sensors: The system requires accurate measurement of the vehicle's speed for WIM calculations. This is often performed by built-in or external radar/laser sensors.
- Display and Data Processing Unit: This central unit receives signals from the sensors, processes them, calculates the axle and gross weight, and displays the results. Modern units are capable of storing, printing, and transmitting data.
- Cabling and Connectors: Industrial grade, weather-resistant cables ensure reliable signal transmission between the sensors and the display.
Advantages and Application Areas
The use of Intercomp's portable WIM solutions brings several strategic advantages for regulatory bodies and the logistics sector.
Roadside Enforcement and Verification
The essential tools of portable WIM systems from the perspective of road safety and infrastructure protection:
- Overload Prevention: Overloaded vehicles damage roads and bridges significantly faster. WIM measurement enables authorities to target weight limit enforcement.
- Increased Safety: Overloaded vehicles have a longer braking distance and reduced stability, increasing the risk of accidents.
- Fast Data Acquisition: Vehicles do not need to stop for measurement (at low speeds), which minimizes traffic congestion at inspection points.
- Data logging: The systems are exceptionally suitable for traffic counting, axle distribution analysis, and mapping freight traffic patterns.
Other Professional Applications
Although the main focus is on road enforcement, these flexible systems can be applied in other areas as well:
- Temporary Work Sites: On construction sites or in quarries where the weight of loaded and unloaded materials needs to be checked quickly.
- Logistics Terminals and Ports: Quick verification of container weights to comply with SOLAS (Safety of Life at Sea) regulations.
- Commercial Fleets: Fleet operators can use them to check the optimal loading of vehicles, avoiding fines and optimizing transport.
