Weigh In Motion(WIM)

Rice Lake Make - Weigh In Motion(WIM) – Truck Scales

A WIM system is: ‘a device that measures the dynamic axle weight of a moving vehicle to estimate the corresponding static axle mass

WIM system is to weigh vehicles whilst they were travelling along the highway, for determining the overload vehicles for enforcement purposes and those falling outside limits to be screened for later static weighing.

WIM systems comprise a number of basic components, with the mass sensor being the most important and fundamental. These Load cell sensor produces a signal whose value depends on the instantaneous dynamic axle load of a moving vehicle.

The need for a WIM :

Trucks with axle load higher than legal limits cause a disproportionately higher percentage of damage to the infrastructure and adverse impact on traffic safety.

When speed is critical and vehicle weighing is an integral part of the operation. The speed limit can be 5 to 10 KMPH

The development of such systems was desirable as Road Authorities sought to obtain more accurate information regarding the type, and weight, of vehicles using their road networks.

Speciality of RICELAKE Weigh-In-Motion Truck Scales

  • Pioneers in Wagon Inmotion Weighing for more than 3 decades and Rice Lake being the market leader provides system with best Technology, Accuracy, Reliability with Proven Track Record(PTR).
  • Robust structure to take care of maximum axle load allowed for ON THE ROAD trucks with 15KMPH speed and with all impact loads due to dynamics of a moving vehicles.
  • The main structure is a Steel structure with concrete deck
  • Concrete Deck also increases the Road Grip and easy to repair / refill, if the need arises within the purview of the user.
  • The sensors are of Superior technology with Double Ended Shear Beam type with imported forged rocker links, ensures faster return to equilibrium / zero, before the next axle comes on the platform.
  • The No. of axles are computed along with their weight to compute total weight of the truck.
  • The Vehicle start and end are identified with Light curtain sensor and with number of axles derived from the number of weight profiles.
