Engineering, procurement and construction (EPC) firms encounter a variety of challenges when taking on a truck scale project, such as managing complex projects with numerous stakeholders, ensuring regulatory compliance and mitigating risks related to cost and schedule overruns. Additionally, they must adapt to the constantly evolving landscape of technology, innovation and sustainability to stay competitive in the marketplace. With infrastructure funding ramping up projects nationwide, it is more critical than ever for EPCs to understand all of the components associated with truck scale projects.

Truck scale projects

A truck scale consists of multiple components that work together to measure a vehicle’s weight. These components can include:

  • Ramps — used to bring the truck to the same level as the scale.
  • Gates — programmed to open and close at specific points during the weighing process to guide drivers.
  • Approaches — allow trucks to enter the scale from a level surface to ensure accuracy.
  • Scalehouse — houses the scale indicator and operator if applicable.
  • Indicators — serve as the control panel for the scale.
  • Computers — house the scale software, automating data capture, speeding up transactions and reducing opportunities for error.
  • Printers — used for printing transaction tickets.
  • Weighbridge — serves as the driving surface for trucks.
  • Junction box — serves as a connection point for the load cells.
  • Load cells — measure the weight on the scale.
  • Load-cell cables — transmits the load cell signal to the indicator.
  • Unattended kiosk — enables drivers to process their own weighing transactions without the need for a scalehouse operator.
  • Traffic control solutions — streamline flow and provide driver instruction.
  • Remote weight displays — displays the truck’s weight to the driver.

The scope of a truck scale project can be intimidating when users realize it involves more than just the weighbridge itself. METTLER TOLEDO is a full-solution provider, meaning that it can provide everything a customer would need for a truck scale project.

Explore the different types of truck scales and the benefits of each listed below.

Truck scale selection criteria

Truck scales are often referred to as the cash register of the customer’s operation. This means that if a truck scale is down for a month, a week or even a day, it can be very costly. Productivity, reliability, accuracy and environmental protection are all key criteria that should be considered when selecting a truck scale. As truck scales are meant to have a long asset life, longevity is also very important. METTLER TOLEDO puts each weighbridge model through lifecycle testing, which simulates 2 million cycles, or 20 years of heavy use.

Understanding load cell technology

Load cells are the sensors that actually measure the weight of the truck pulling onto the scale. There are many types of load cells, all of which vary greatly in accuracy, reliability, environmental protection and more.

Explore the different types of load cells and the benefits of each below.

Key features of POWERCELL PDX load cells

  • Digital technology: Unlike traditional analog load cells, POWERCELL PDX utilizes digital technology, providing premium accuracy and reliability. Digital signal processing reduces the impact of electrical noise, ensuring consistent and precise measurements.
  • Robust design: POWERCELL PDX is designed to withstand harsh industrial environments. It features hermetic sealing, protecting internal components from moisture, dust and other contaminants. This robust design ensures long-term durability and minimal maintenance.
  • Lightning protection: One of the standout features of a POWERCELL PDX load cell is its built-in lightning protection. This ensures that the load cell remains operational even in environments prone to electrical surges up to 80,000 amperes (2.5 times the average lightning strike), reducing the risk of downtime and costly repairs.
  • Enhanced diagnostics: POWERCELL PDX load cells come with advanced diagnostic capabilities. They can detect potential issues, such as overloads or electrical problems, and alert operators before they escalate into significant problems. This proactive approach helps maintain optimal system performance and reduces the likelihood of unexpected failures.
  • Simplified installation: POWERCELL PDX is designed for easy installation. Its plug-and-play design allows for quick setup, minimizing downtime and ensuring a fast return to operation.
