Why is vehicle weighing so important? The correct determination of the weight of raw materials and final products has a direct impact on economic efficiency of every company. Nowadays, weighing systems are often part of the comprehensive system monitoring the material flow. Law enforcement weighing The government not only aims at improving the road traffic safety, but also at protecting state property. The widespread introduction of overload monitoring has become a common topic for European transit countries. Improvement of logistical processes An overload container not only worsens the traffic safety and reduces the life of road surface; it also complicates the economic situation of the centre operator. The queue forming on the driveway to the site creates a bottleneck reducing the passability of the centre, and its operators or investors are forced to think about an efficient solution. Instead of the common weighing bridges, it is useful to consider the use of the more efficient Weigh-in-Motion (WIM) system. That s why they are increasingly becoming an integral part of the comprehensive system monitoring the material flow in the company. So why not to be prepared? Utilize the possibility of checking the weight before transporting goods by means of a certified device! When choosing a weighing system, the most important parameter is not its price, but the long-term reliability of the product under hard operating conditions. With years of experience in the area of scales and weighing, we will certainly find a suitable solution for your operation! General description of the weighing on roads concept Based on our experience with operating the weighing stations in the Czech Republic and other countries, we recommend to the client who is considering direct charges of overload vehicles, to build up a two-stage weighing station with a high-speed weighing system (HS WIM) at the first stage for a quick preselection of overload vehicles from the traffic flow, and a much more accurate low-speed weighing system (LS WIM) at the second stage, which is officially approved for inspection (official) weighing. The high measurement accuracy of second stage weighing reduces the number of appeals in administrative proceedings and significantly increases the operational efficiency of the whole station low-speed weighing system works with 5 times smaller error that enables to set a penalty to much more offenders. Key: 1) High-speed weighing system load sensors Inductive loops 2) Camera system on a portal gate Colour overview camera IR camera for licence plate reading IR illuminator for night vision 3) Roadside cabinet with electronics Evaluation system for weighing data and video data Communication with 2nd stage - low-speed weighing 4) System of variable message signs and permanent traffic signs for slowing down and directing the overload vehicle to law enforcement weighing at the 2nd stage of the station (vehicles can also be directed by a police officer) 5) Low-speed weighing system VM-1.2 for precise law enforcement weighing in motion. Weighbridge is embedded in a weighing zone 6) Signal lights (2 units) 7) Information display 8) Operator s workplace Officer attending to transgressors vehicles Fine collection and initiation of administrative proceedings 9) Parking area for transgressors vehicles Two stage weighing station with a high speed (HS WIM) and low speed (LS WIM) weighing system Accurate systems for low speed Weigh-in-Motion We offer these two system types: VM-1.2 Stationary Dynamic System for Automatic Weighing vehicles in Motion Portable System PW-10 for occasional checking vehicle loading
VM-1.2 Stationary Dynamic System for Automatic Weighing vehicles in Motion The TENZOVAHY WIM System VM-1.2 is a revolutionary change in the way of weighing cargo at logistical terminals, in forwarding and construction companies as well as for law enforcement on roads and highways. Vehicles are weighed while crossing the bridge. Weighing is then automatically evaluated and processed by a computer information system. Product description Scales provides real-time information to the dispatcher centre about immediate weight of the vehicle, all data about its operations, including statistics, trends and possible extreme variations in weighing. An easy-to-use software not only allows for keeping a well-arranged record of vehicles, materials and carriers, but also for issuing invoices and balances and exporting data to the company s related information systems. This facilitates further planning and process optimization. Additional devices make the automatic operation even easier such as boom barriers, traffic lights, video cameras, automatic operation terminals, automatic number plate recognition etc. Important and useful software tools Scales for Law Enforcement Software For law enforcement on vehicle weighing stations, border crossings and toll sites we provide automatic vehicle load analysis according to national load limits. Advanced features like vehicle classification, law compliance checking, Fine calculation, or Load Equivalency Factors settings (LEF) are implemented in this user-friendly software without any additional costs for the user. Data management is included.

Main advantages Besides total vehicle weights, the system determines also axle loads, group loads and much more Higher passability for vehicles Possibility of unattended operation Smooth integration into company information system All-year operation High quality and long life Certification for both Commercial Weighing as well as Official Law-Enforcement Weighing Scales for Weighing vehicles in Motion VM-1.2 excels reliability and a number of unique features The Weighing Bridges are thoroughly protected against corrosion by hot-dip galvanizing zinc-coating. Load cells are over dimensioned to resist even heavy overloaded vehicle axles and with dynamic shocks that arise during weighing. We use only stainless steel sensors by renowned European manufacturers. Base frames of scales are equipped with a heating cable, which is switched and controlled automatically - heating is thus in operation only for the necessary time saving electricity. These scale work smoothly even in severe frost. Weighing range is from 400 up to 20 000 kg per axle, while the number of vehicle axles is not limited for weighing. Gross vehicle weight is not limited (it may theoretically be e.g. 10 x 20 t = 200 tons). Vehicle length is not limited. Speed of the vehicles during weighing can be up to 16 km/h. Software for trade weighing is developed for control of material supply in construction yards, sandpits, quarries, concrete production yards, waste dumps etc. and offers automatic reporting of weighed material, invoice generation, outputs for company accounting or material supply system. Vehicle weighing can be also fully automated with chip card terminals on unmanned sites and under supervision of up to four cameras. Technical specification Note: Contact us for other optional accessories Weighing on unmanned sites Vehicles are identified by chip card, material is selected by the driver on keyboard and the vehicle is then weighed in a fully automatic mode.
