Truck scales play a crucial role in controlling vehicle loads, ensuring traffic safety, and protecting road infrastructure. This article analyzes the advantages and disadvantages of above-ground truck scales, while also providing detailed information about the technical specifications and outstanding benefits of this type of scale.
Pros and Cons of Above-Ground Truck Scales
Advantages:
- Easy Maintenance and Repair: Above-ground truck scales are installed on the ground surface, making maintenance, warranty, and repair easier compared to in-ground scales. Since they are not submerged, the equipment is less affected by humidity, thereby increasing the durability and lifespan of the system.
- High Durability: Due to their elevated and dry installation location, above-ground scales are less susceptible to environmental impacts, reducing rust and damage. This helps extend the lifespan and reduce maintenance costs for the scale.
- Popularity: Due to the advantages in maintenance and durability, above-ground truck scales are widely chosen and used by many businesses.
Disadvantages:
- Space-Consuming: Constructing an above-ground scale requires more space because of the need to build ramps at both ends of the scale. Each end needs an additional length of about 2.5m and a width of 3m for trucks to move up and down safely. This can be challenging for areas with limited space.
