Above-ground truck scales, also known as surface-mounted truck scales, are a common type of weighing system used across various industries for weighing trucks and their cargo. In this section, we provide a detailed overview of above-ground truck scales, including their design, installation process, advantages, and applications.
1. Weighing Platform:
The weighing platform serves as the surface on which the truck drives to be weighed. It is constructed using durable materials such as steel or concrete to withstand heavy loads and harsh environmental conditions.
Load cells are sensors placed beneath the weighing platform to measure the weight of the truck and its cargo. These load cells convert the applied force into an electrical signal, which is then processed to calculate the total weight.
The support structure includes beams, columns, and other components that hold the weighing platform in place and distribute the weight evenly. It is designed to provide stability and structural integrity to the entire system.
The terminal or weight indicator is the control unit that receives signals from the load cells and displays the weight readings. It may also include additional features such as data storage, connectivity options, and software integration for data management.
1. Site Preparation:
Before installation, the site where the truck scale will be placed needs to be prepared. This may involve leveling the ground, ensuring proper drainage, and laying a stable foundation to support the scale.
The weighing platform is then installed on the prepared site, typically using bolts or welding to secure it in place. The load cells are positioned beneath the platform, and cables are routed to connect them to the terminal.
Once the scale is installed, it needs to be calibrated to ensure accurate weight measurements. This involves applying known weights to the scale and adjusting the calibration settings as needed. The scale is then tested to verify its accuracy and performance.
Any final adjustments are made to optimize the scale's performance, and it is commissioned for regular use. This may involve configuring software settings, conducting additional tests, and training personnel on how to operate the scale properly.
