Axle assembly weighing

Dynamic Weighing - Axle Group Weighing

Axle assembly weighing

Axle-group dynamic weighing system—An optimal solution featuring the golden ratio design, balancing high precision with ease of construction.

The Axle Group Weighing System is an innovative dynamic weighing system that features a unique 4-meter golden-ratio weighing platform design. It enables the simultaneous, comprehensive weighing of single axles, dual-axle assemblies, or triple-axle assemblies on vehicles. Compared to conventional single-axle scales, this system significantly reduces the impact of vehicle vibrations on weighing accuracy, achieving a dynamic accuracy level of Grade 1 as per national standards.
The system integrates YINTAILI Technology’s patented “tensile sensor” technology, which can effectively detect and correct cheating behaviors such as “dragging the scale,” “jumping the scale,” and “rushing the scale.” Its unique concave-convex anti-slip design is suitable for various harsh climates across both northern and southern regions. The ZCS-60A-DZ achieves measurement accuracy comparable to that of full-vehicle scales at a construction cost close to that of single-axis scales, making it a highly cost-effective choice for weigh-in-motion toll collection and overloading detection on highways.

Overview

Grade 1 accuracy, rejecting error disputes

With the extended 5.1-meter weighing platform, the system can fully accommodate a triple-axle assembly. Coupled with an advanced Kalman filtering algorithm, it effectively eliminates interference from bumps and vibrations during vehicle movement, enabling accurate weighing at speeds ranging from 1 to 20 km/h. National Standard Grade 1 Weighing accuracy (error ≤ ±0.5%), significantly reducing disputes over weight between drivers and passengers.

Patent-based anti-cheating measures plug revenue loopholes.

To counter the common cheating tactic used by drivers—“dragging the scale” (braking and accelerating to pass)—we have introduced a patented... Horizontal Tension Sensor It can monitor in real time the horizontal force exerted by vehicles on the weighing platform, and automatically compensate for weight loss through a dynamic model, leaving no room for fraudulent activities and ensuring that toll fees are accurately collected.

Civil engineering costs cut in half, making renovations easier.

Compared to full-vehicle weighbridges that often measure 18 meters in length, the ZCS-60A-DZ requires only a smaller pit. The amount of foundation work is reduced by more than 60%, and the construction period is significantly shorter—making it particularly well-suited for toll lanes with limited space or for upgrading and renovating older sites, allowing traffic to be quickly restored.

Core features

Accuracy class: Dynamic Level 1 / Static Level III
Weighing method: Shaft-group type (single-axis/combined shaft weighing)
Weighing platform dimensions: 5100mm (length) × 3300mm (width)
Rated load: 60t (maximum axle group weight)
Overload capacity: 200% safety overload
Travel speed: 1–20 km/h
Anti-cheating: Patent-based Tension Compensation Technology
Protection rating: Sensor IP68 / Control cabinet IP65

The “mainstay” of weight-based tolling and overlimit detection

The ZCS-60A-DZ is widely used at highway toll booth entry lanes for issuing toll cards, exit lanes for weight-based toll collection, and fixed weigh-in-motion stations on national and provincial roads. By precisely coordinating the separator, axle detector, and weighing platform, it automatically performs vehicle separation, axle type identification, and weight calculation, ensuring that the toll calculation for each vehicle is accurate, fair, and traceable.

Craftsmanship-designed, stable as Mount Tai.

5.1-meter golden countertop, ensuring a stable center of gravity.

Why 5.1 meters? Because this is the optimal dimension for simultaneously accommodating a standard triple-axle assembly of heavy-duty trucks.

The ZCS-60A-DZ abandons the short-platform design that requires vehicles to frequently drive onto and off the weighing platform. When the triple-axle assembly is fully seated on the weighing platform, the vehicle’s center of gravity remains stable, eliminating inter-axle interference forces. Coupled with a highly rigid, all-steel U-beam structure, even under overload conditions of up to 100 tons, the weighing platform remains stable and undeformed, ensuring long-term measurement accuracy.

Lateral Force Monitoring Unveils the “Drag-Weighing” Trick

“Dragging the scale” is a cheating method used by truck drivers who apply intermittent braking or acceleration on the weighing platform to generate a horizontal force that counteracts the vertical gravitational force. Traditional equipment is powerless to detect this trick.

This system innovatively introduces Tension sensor It’s as if the weighing platform has been equipped with “lateral nerves.” As soon as an abnormal horizontal tensile force is detected, the system’s algorithm immediately kicks in, calculates the lost weight, and compensates accordingly, ensuring that the output reflects the vehicle’s true physical weight.

Innovative non-slip mesh, suitable for both north and south.

Ordinary steel plate countertops are extremely slippery in rainy or snowy weather, posing a safety hazard. We have adopted a unique... Convex-Concave Rivet Anti-Slip Mesh Design.

The non-slip pillars, with a diameter of 26 mm and a height of 10 mm, are evenly distributed. Not only do they provide exceptional traction on rainy days, but they also help break up ice layers during freezing conditions in northern winters, effectively preventing vehicles from skidding. At the same time, this structure boasts excellent corrosion resistance and wear resistance, ensuring a service life of over 10 years.

Fully sealed welding, unafraid of harsh operating conditions.

The core load cell adopts a bridge structure and... All-laser welded seal The process features internal nitrogen purging for protection, achieving an IP68 protection rating.

This means that even when submerged in water for extended periods, it can continue to function normally and is completely immune to acid rain and salt-spray corrosion. Paired with an industrial-grade control cabinet equipped with triple-level lightning protection and a watchdog reset function, the system can maintain stable 24-hour, 7-day operation even in harsh outdoor environments characterized by high temperatures, high humidity, and complex electromagnetic interference.

Precise Dynamic Weighing and Overweight Vehicle Detection & Guidance for Return

With the deepening implementation of the “National Unified Network” operation and the policy of “mandatory inspection for trucks and prohibition of overloaded vehicles,” highway toll plazas at entry points are facing unprecedented traffic pressures. Traditional static weighing systems are inefficient and prone to severe congestion; meanwhile, outdated dynamic weighing systems often prove inadequate when confronted with new cheating tactics such as skipping weigh stations, speeding through weighbridges, or driving in S-shaped patterns. Moreover, these systems struggle to accurately capture vehicle dimensions—length, width, and height—leading to oversight and misjudgments of overloaded vehicles. This not only results in lost toll revenue but also poses serious safety risks to highways.
