Selleton helps customers plan relocation procedures, including re-anchoring, re-leveling, and recalibration schedules to maintain accuracy and compliance throughout the life of the scale.
Axle Scales and Off-Road Vehicle Scales
Axle scales provide a different approach to truck weighing, measuring individual or grouped axles rather than total vehicle weight. This method is preferred when load distribution verification or DOT pre-screening is the primary goal.
Portable axle scales typically consist of matched pad pairs with capacities of 60,000 lb or more per axle. These compact systems include ramps and either a portable indicator or tablet-style display for field weighing operations.
Important distinction: Many portable axle scales are intended for weight checks and load distribution verification rather than commercial transactions. Unless specifically certified as legal for trade, these systems should not be used for billing purposes.
Off-Road Vehicle Scales
Off-road truck and haul scales handle the demands of large articulated trucks, mining vehicles, and heavy construction equipment. Key features include:
-
Higher weight capacities for massive payloads
-
Wider platforms to accommodate oversized tires
-
Heavy-duty steel structures built for the toughest environments

FAQ
How do I know if my truck scale needs to be legal for trade?
If customers are billed or paid based on truck weight—for example, selling aggregates, grain, scrap metal, or waste by the ton—the scale must be NTEP-certified and legal for trade. This applies to any commercial transaction where weight determines price.
Purely internal checks, such as verifying payloads before hitting a public weigh station, can use non-legal-for-trade scales, though accurate equipment remains important for operational efficiency.
Confirm requirements with your state’s weights and measures agency and maintain documentation for every certified scale on site. Selleton can help identify whether an application requires legal for trade approval and recommend compliant models accordingly.
What foundation do I need for a truck weigh scale?
Full-length truck scales typically require reinforced concrete foundations engineered to handle total vehicle loads and local soil conditions. Foundation design affects both accuracy and longevity.
Pit foundations place the scale deck flush with the surrounding ground, streamlining traffic flow but creating drainage and access challenges. Above-ground installations use approach ramps and simplify maintenance access but require more horizontal space.
Work with civil engineers or follow manufacturer foundation drawings when planning a new scale installation. Selleton provides foundation guidelines and can review plans to help ensure long-term structural integrity and weighing accuracy.
How long does a truck scale last under heavy use?
A well-built commercial truck scale, properly installed and maintained, can often deliver 15 to 20 years or more of service, even in demanding environments. Quality construction and regular maintenance are the keys to longevity.
Factors that affect lifespan include traffic volume, axle loading patterns, climate exposure, corrosion conditions, and maintenance practices. Regular inspections for deck wear, weld fatigue, water intrusion, and cable or load cell damage catch issues early before they become expensive problems.
Selleton’s heavy-duty platforms are designed for long-term industrial use. Components like indicators and load cells can be upgraded over time to extend system life without replacing the entire scale.
Can I move my truck scale to a new location?
Many modular and portable truck scales are designed to be disassembled, transported, and reinstalled at a different site. This flexibility is a key advantage for operations that shift locations over time.
Relocation requires planning: lifting equipment, foundation work at the new site, rewiring, and full recalibration to restore accuracy and compliance. Keep original installation drawings and documentation to simplify reassembly and ensure the deck is re-leveled correctly.
Selleton can advise on relocation feasibility for specific models and help arrange service support for setup and calibration at the new location.
How accurate are truck weigh scales, and what affects accuracy?
Modern truck scales designed for legal for trade use typically achieve accuracy within a few divisions of their scale interval—for example, 20 lb or 50 lb increments—when properly installed and maintained. This precision meets NTEP standards for commercial transactions.
Key factors that influence accuracy include foundation stability, proper leveling, environmental conditions, electrical noise, and regular calibration with certified test weights. Temperature fluctuations and moisture can also affect readings over time.
Repeated heavy overloading, poor drainage, or structural damage can gradually degrade accuracy if not addressed. Selleton designs systems with robust load cells, sealed junction boxes, and high-quality indicators to maintain stable performance across years of demanding operation.
