How to Operate a Concrete Weighbridge

How to Operate a Concrete Weighbridge

Operating a concrete road weighbridge, whether surface-mounted or pit-mounted, requires specific procedures involving initial preparation, weighing operations, maintenance, and repairs. Following these steps ensures accuracy and efficiency in weighing operations.

Initial Preparation

• User Training:

  • Equipment Operation: Users should receive training on operating the weighbridge, display systems, and controllers.
  • Safety Training: Necessary safety training regarding weighbridge operation and vehicle handling should be provided.

• Initial Calibration:

  • Standard Weights: Use standard weights for weighbridge calibration.
  • Precise Adjustments: Precisely adjust the electronic systems to ensure measurement accuracy.

Weighing Operation Process

• Vehicle Entry:

  • Designated Entry Route: Vehicles should enter through the designated route and slowly drive onto the weighbridge platform.
  • Vehicle Positioning: The vehicle must be fully positioned on the platform, with all wheels on the weighbridge.

• Weighing Operation:

  • Complete Vehicle Stop: The vehicle must come to a complete stop for accurate weight measurement.
  • Initial Weight Recording (Tare): The empty vehicle weight (tare) is recorded. This is done the first time a vehicle uses the weighbridge.
  • Loaded Weight Recording: After loading, the vehicle is weighed again, and the gross weight (vehicle plus load) is recorded.

• Net Weight Calculation:

  • Load Calculation: The load weight is calculated by subtracting the tare weight from the gross weight.
  • Data Recording: The net weight information is recorded in the system, and a receipt is issued.

Operating a Surface-Mounted Concrete Road Weighbridge

• Platform Preparation:

  • Platform Leveling: Ensure the platform is level before each weighing for greater accuracy.
  • Platform Cleaning: Ensure the platform is clean and free of obstructions for greater accuracy.

• Weighing Operation:

  • Vehicle Entry: The vehicle slowly enters the platform via ramps and is fully positioned on it.
  • Complete Stop: The vehicle must come to a complete stop on the platform.
  • Weight Recording: After a complete stop, the weight is recorded by the electronic system.

Operating a Pit-Mounted Concrete Road Weighbridge

• Platform Preparation:

  • Platform Cleaning: Ensure the platform is clean and free of obstructions for greater accuracy.
  • Platform Leveling: Ensure the platform is level before each weighing for greater accuracy.

• Weighing Operation:

  • Vehicle Entry: The vehicle slowly enters the platform, which is level with the ground, eliminating the need for additional ramps.
  • Complete Stop: The vehicle must come to a complete stop on the platform.
  • Weight Recording: After a complete stop, the weight is recorded by the electronic system.

Display and Data Recording Systems

• Digital Displays:

  • Display Installation: Displays are installed in accessible and visible locations for drivers.
  • Weight Display: Displays the vehicle’s precise weight in real-time.

• Data Recording and Management Systems:

  • Data Recording: Net weight information and other related vehicle details are recorded in the system.
  • Receipt Issuance: A net weight receipt is given to the driver.

Maintenance and Repairs

• Periodic Maintenance:

  • Periodic Inspections: Regularly inspect the weighbridge equipment to ensure proper functioning.
  • Platform Cleaning: Regularly clean the platform to prevent the accumulation of debris.

• Repairs:

  • Replacement of Defective Parts: Promptly replace defective parts to maintain the weighbridge’s accuracy and performance.
  • Recalibration: Recalibrate the weighbridge as needed to ensure measurement accuracy.

By following these procedures, you can ensure the accuracy and efficiency of the weighbridge and perform weighing operations correctly and accurately.
