Unattended Truck Scale System

Automate Your Truck Weighing Process

An unattended truck scale system combines a weighbridge with suitable identification, traffic-control, and weighing-management components to support vehicle weighing with reduced routine operator involvement.

For industrial facilities that weigh trucks throughout the day, an appropriately configured system can help standardize weighing procedures, manage transaction records, and improve the flow of vehicles through the weighing area.

Fangda provides truck scale and weighbridge solutions for projects with different capacity and installation requirements. The automation configuration should be selected according to your vehicle fleet, site layout, operating process, and data-management needs.

Whether you operate a manufacturing plant, logistics center, quarry, mine, grain depot, or bulk-material facility, start by defining how vehicles enter the site, how they are identified, how weighing transactions are recorded, and when staff intervention is required.

What Is an Unattended Truck Scale?

An unattended truck scale is a vehicle weighing arrangement designed to reduce the need for an operator to manually manage every weighing transaction at the weighbridge.

Depending on the selected system, the configuration may combine a truck scale, weighing indicator, software, vehicle-identification equipment, traffic-control devices, and communication interfaces.

The exact level of automation varies by project. Some facilities need only electronic transaction recording and basic weighing management. Others may require vehicle identification, entry and exit controls, integration with enterprise software, or a more comprehensive automated workflow.

Before selecting a system, define the required functions and confirm the compatibility of each component.

Key Components of an Unattended Weighbridge System

1. Truck Scale and Weighing Indicator

The weighbridge measures the vehicle load, while the weighing indicator receives and displays the weighing signal. The selected scale capacity, platform dimensions, load-cell configuration, and indicator must suit the intended vehicles and operating conditions.

Fangda's stated truck scale range covers 30 to 200 tons. Confirm the availability and specifications of the selected model before finalizing the automation design.

2. Vehicle Identification

A project may use one or more methods to identify vehicles before or during weighing. Depending on the requirements and available equipment, these may include RFID tags, card readers, license-plate recognition cameras, or operator-assisted identification.

Identification technology should be selected according to vehicle traffic, lighting conditions, tag management, privacy requirements, and integration needs.

3. Traffic Control Equipment

Automated traffic management may incorporate barriers, traffic lights, sensors, or other control devices. These components can help coordinate vehicle movement and reduce the risk of multiple vehicles entering the weighing platform at the same time.

The actual equipment, control logic, and safety interlocks must be confirmed for the selected project.

4. Weighing Management Software

Weighing software may record transaction details, vehicle identifiers, weight readings, timestamps, and other configured information. Reporting, user permissions, data export, and connections to other business systems depend on the software and integration scope.

Confirm the required functions, supported interfaces, data-retention policy, and reporting format before ordering.

5. Monitoring and Communication

Some installations require network communication, remote monitoring, cameras, or connections to a plant control system. These functions depend on site infrastructure, software compatibility, and the agreed project scope.

A system design should identify what needs to communicate, where records are stored, and what happens when a device or network connection is unavailable.

How Does an Unattended Truck Weighing Process Work?

The process should be designed around the site's actual operating rules. A typical configured workflow may include the following steps.

Step 1: Vehicle Arrival

A vehicle approaches the weighbridge entrance. Site signs, sensors, or traffic-control equipment may guide the driver to the correct position.

Step 2: Vehicle Identification

The system identifies the vehicle using the configured method, such as an RFID tag, card, license-plate recognition, or another approved workflow. Manual confirmation may still be required for exceptions.

Step 3: Vehicle Positioning

Traffic controls guide the vehicle onto the weighing platform. The weighing procedure should ensure the vehicle is positioned correctly and that the weighing conditions meet the system's operating requirements.

Step 4: Weight Capture

The weighing indicator provides the weight reading to the configured system. Transaction logic should account for stable weight conditions and any required validation before a record is accepted.

Step 5: Transaction Recording

The software records the configured vehicle, weight, time, and transaction information. Additional data fields and approval steps depend on the site's weighing procedure.

Step 6: Vehicle Exit

When the required checks are complete, the system may permit the vehicle to leave through the configured traffic-control process. Exceptions, failed identification, unstable readings, and equipment faults should have a defined escalation procedure.

This workflow is an implementation example, not a guarantee that every function is included in every Fangda truck scale package. Confirm the final workflow and component list before implementation.

Benefits of Truck Scale Automation

More Consistent Weighing Procedures

A defined system workflow can help apply consistent steps for vehicle identification, weighing, and transaction recording.

Better Transaction Traceability

Configured electronic records can make it easier to retrieve vehicle and weighing information for reconciliation, reporting, and operational review.

Reduced Routine Manual Intervention

Depending on the level of automation, staff may spend less time manually entering vehicle information or managing routine transactions. Staff oversight is still important for exceptions, maintenance, and operational safety.

Improved Traffic Coordination

Suitable traffic-control equipment and operating rules can help organize vehicle movement around the weighbridge. The actual benefit depends on site layout and traffic volume.

Potential for System Integration

Where compatible interfaces are available, weighing records may be connected to inventory, dispatch, ERP, or other business systems. Interface availability and development work should be confirmed before project approval.

Truck Scale Capacity and Installation Options

Automation should be designed alongside the physical weighbridge rather than treated as an isolated software purchase.

Fangda's stated capacity range covers 30 to 200 tons. The appropriate capacity depends on the maximum gross vehicle weight, axle-load distribution, weighing frequency, platform dimensions, and applicable requirements.

Consider the following options when planning your system:

• 60 Ton Truck Scale: Review the requirements for the intended commercial or industrial vehicle fleet.

• 80 Ton Truck Scale: Compare capacity and platform requirements for the planned weighing operation.

• 100 Ton Truck Scale: Assess the required capacity, vehicle dimensions, and weighing frequency.

• 120 Ton and 150 Ton Truck Scales: Evaluate project-specific needs for selected heavy-duty applications.

• 200 Ton Truck Scale: Confirm the intended vehicle loads and engineering requirements for high-capacity weighing.

Platform structure, including available U-beam designs, should be confirmed for the selected model. Installation may be pit-mounted or pitless depending on product availability, civil works, drainage, vehicle access, and site conditions.

Applications
