All kinds of road and industrial scales covered by Shiraz Pak Tozin
Shiraz Pak Tozin has complete control over the design, repair and support of all kinds of road weighing technologies. According to the structure of the structure and the method of installation, the repair methodology of each scale is different and requires appropriate expertise:
60 ton trolley scales: These scales, which usually measure 16 x 3 meters, are the most widely used type in terminals and factories. The pressure on the chassis, platform plates and weight sensors is very high in this type, and their repair and alignment requires advanced hydraulic equipment and knowledge of structural engineering.
50 and 20 ton truck scales: these devices, which are designed in dimensions of 8 x 3 meters or similar sizes, are made of metal, metal concrete and all concrete. Adjusting the distance of the structure from the concrete walls and checking the surface compression is one of the key stages of repair services in these models.
All-metal and metal-concrete scales: Metal scales have more elastic resistance, but over time and due to repeated dynamic stresses, they may bend or break the welds. Shiraz Pak Tozin provides chassis strengthening services, specialized industrial welding and replacement of load plates in the best way.
Industrial digital floor scales and hanging scales: In addition to heavy road systems, Shiraz Pak Weighing all types of digital floor scales from 500 kg to 5 tons capacity, which are used in warehouses, banking and packaging centers, undergo board repairs, sensor replacement and software modification.
The most important common faults in digital and road scales
Road scales are complex systems composed of mechanical, structural parts and microelectronic circuits. Knowing the factors of failure helps factory managers to contact Shiraz Pak Tozin in case of the first symptoms:
Fluctuation and jumping of weight display figures: This problem, which is one of the most common signs of malfunction, usually occurs due to moisture infiltration into the distribution box, damage to the cover of the load cell cables, severe fluctuations in the mains electricity, or frequency and electromagnetic interference.
Weight difference in the corners of the scale: When a vehicle is placed on different points of the scale and shows different figures, so-called corner imbalance has happened. This problem is caused by damage to one or more load cells, misalignment of the support legs, or non-adjustment of the variable resistors in the junction box.
Chassis sticking to the foundation: In level models, the accumulation of mud, sand or strong seasonal expansion and contraction can cause the platform to stick to the foundation wall. This event transfers part of the pressure of the weight to the ground and causes the weight to appear lower than the actual amount.
Calibration error and linear deviation: Over time and loading pressures, sensors experience material fatigue and lose linear response to pressure, which requires recalibration with reference weights.
Specialized stages of road scale repair by Shiraz Pak Tozin
The engineering team of Shiraz Pak Tozin implements the process of troubleshooting and repairs based on standard engineering guidelines and following the following basic steps:
Preliminary examination and visual inspection: In the first step, the mechanical health of the platform, the distance between the shock absorbers, the cleanliness of the drainage channels under the scale, the absence of buried load cells in the soil and the alignment of the structure are checked physically.
Ohmic and insulation test of load cells: Shiraz Pak Tozin technicians measure the input resistance, output resistance and insulation resistance of the load cells relative to the body using millivolt meters and industrial precision ohm meters to ensure the health of the core and strain gauges.
Junction box inspection: The distribution box is checked and in case of board oxidation or moisture penetration, the damaged parts are replaced and the circuit is isolated with special waterproof materials.
Inspection of the display, load cell and wiring: central processors and communication ports are tested, and interface cables that are cut, torn or chewed by rodents are replaced with industrial shielded cables.
Final calibration and issuance of health certificate: after fixing the defects, the scale is adjusted and leveled with standard calibrated weights and the functional accuracy test is recorded with repeated movement maneuvers.
Periodic calibration services of digital and road scales
Calibration of the beating heart is the maintenance of weighing systems. Even if the scale does not face obvious defects, over time it will suffer zero shift and proportional coefficient change. Shiraz Pak Tozin, having standard test loads in various tonnages, provides road scale calibration services throughout Fars province.
The calibration process in Shiraz Pak Weighing includes initial zero adjustment, measurement accuracy test in step weights, load eccentricity test, reproducibility test with multiple passes of loaded vehicles and storage of new parameters in display memory IC. Carrying out this process periodically prevents tax disputes, penal crimes and hidden losses of factories.
Repair, supply and replacement of analog and digital load cells
Load cells are the most sensitive and decisive part of any road scale. These parts are compression, column or shear type and convert mechanical forces into millivolt electrical signals. Shiraz Pak Tozin, as a supplier and expert in the repair of digital and road scales in Shiraz and the cities of Fars province, has original parts and load cells with international OIML approval available in its central warehouse.
