Irrefutable Solution for Trucking Terminals

Trucks with axle load higher than legal limits cause a disproportionately higher percentage of damage to the infrastructure and adverse impact on traffic safety. Essae Truck Weigh in motion System (TWIM) is a robust, reliable, maintenance-free weighing mechanism designed for use on highway entries with non-stop heavy traffic. Weighing accuracy and performance are approved for trade use and for law enforcement purposes.

When speed is critical and vehicle weighing is an integral part of the operation, Essae TWIM system provides significant cost savings over full-platform and axle scales. The vehicle loads (wheel, axle, GVW, load ratios) are automatically analysed, compared to legal limits and results are displayed on operator’s PC monitor, the driver gets the corresponding printout and the data are also recorded for further reporting or can be sent via LAN or Internet to the server.. This minimizes operator’s mistakes, offers inbuilt data protection and allows vehicle throughput up to 180 vehicles per hour.

TWIM for Toll Plaza, Toll Roads and Bridges

The vehicle weight, not the number of axles, determines wear and tear of roads. Toll authorities now use weight-based tolling, which relies on weigh in motion technology to determine the proper toll classification while keeping the traffic movin.

Essae Automatic TWIM weighing system

Its rigid construction significantly improves scale reliability in heavy-duty operation and helps to achieve precise positioning into the road during installation thus reducing the installation costs. The weighbridge is connected to traffic lights and signal horn to control vehicle movement. Video camera for vehicle detection and vehicle image capturing can be delivered as optional equipment.

Key Benefits
TWIM for Seaports

Essae TWIM system provides the ability to weigh thousands of containers prior to loading onto ships without the delays caused by trucks stopping at static scales.

TWIM for Border Crossings

The vehicle weight, not the number of axles, determines wear and tear of roads. Toll authorities now use weight-based tolling, which relies on weigh in motion technology to determine the proper toll classification while keeping the traffic moving.


The Proprietary software ensures fully automatic weighing. Advanced functions like the Vehicle Weighing configuration and classification, law compliance checking, fines computing, or LEF calculations are implemented without any additional costs for the user.
