Gantry‑Mounted LiDAR Volume Measurement System: Earth‑rock Volume Measuring Equipment for Muck Trucks

The muck transportation industry has long‑standing pain points associated with inaccurate weigh‑bridge measurements. On rainy days, high moisture content in materials can add several tons to the weight of a single truckload of wet soil. Sand and gravel also vary greatly in density; the weight of rock and sand of the same volume can differ by up to 30%. When settling accounts by weight, mine operators suffer losses while fleets lodge constant complaints, leading to endless reconciliation disputes at month‑end.

Chongqing Jinyun Robotics Co., Ltd. has launched the gantry‑mounted LiDAR volume measurement system. It bypasses weight‑based measurement entirely. By scanning truck compartments with LiDAR to calculate volume for settlement, it delivers fair results accepted by both parties.

Core Problems Solved

Simply put: the system calculates the actual loaded cubic volume inside truck compartments, regardless of material moisture content or density.

Traditional weighbridges are heavily affected by moisture and material density. The weight of one batch of material can vary by several tons between sunny and rainy weather. LiDAR volume measurement adopts a different approach. As vehicles pass through the gantry, millimeter‑level LiDAR performs non‑contact scanning on truck compartments. A 3D point‑cloud model of loaded materials is generated within 3 seconds to compute actual loading volume. Variables such as moisture and density are eliminated, delivering a unified and transparent settlement standard.

More importantly, the system works without network reliance. Data is stored locally and operates normally at remote mines and field construction sites with poor or even zero network coverage. Measured data is saved instantly and uploaded in batches once network connectivity is restored, ensuring no data loss.

Easy Installation

Featuring a gantry‑style framework, the system is fixed on‑site like assembling a portal frame and ready for operation after power‑on. No ground breaking, no buried ground‑sensing coils, and no on‑board equipment installation on individual trucks. Vehicles pass at normal speed without stopping or decelerating. A single lane can easily process over 1,000 vehicles per day. For high‑traffic sites such as muck transfer yards and mine exits, it prevents traffic bottlenecks and queue‑ups — efficiency is critical for such operations.

Real‑world Case: A Muck Disposal Site in Chongqing

One downtown muck disposal site in Chongqing handles around 600 muck truck trips daily. Previously it relied on weighbridge measurement. In rainy weather, fleets complained about losses when settling by weight due to wet soil. Meanwhile, site operators suspected under‑loading when estimating by truck trips, resulting in frequent conflicts.

After deploying the gantry‑mounted LiDAR volume measurement system developed by Jinxin Technology:

1. Unified settlement standard: Switching from ton‑based to volume‑based settlement completely eliminates moisture interference. Monthly disputes dropped from more than ten to zero.
2. Doubled traffic efficiency: Trucks no longer need to stop for weighing. Average passing time is reduced from 20 seconds to 3 seconds, boosting daily throughput by 40%.
3. Readily accessible data: Scanned images and volume records for every vehicle are stored locally. Reports can be exported in one click in the backend, removing manual paperwork for account reconciliation.

As quoted by the site manager: “Drivers no longer need to get off for weighing. I no longer worry about confusing calculations on rainy days. Volume figures pop up immediately after scanning, and everyone accepts the results.”

Applicable Scenarios

• Muck transfer yards: High‑volume traffic, frequent settlement requiring fast and impartial volume data
• Mines & sand‑gravel plants: Diverse materials with large density differences, frequent disputes under weight‑based settlement
• Field & remote mining sites: Poor network conditions requiring offline‑capable independent measuring equipment
• Earth‑rock engineering: Precise calculation of transportation quantities for cost control

Conclusion

Shifting from dispute‑prone weight weighing to volume‑based settlement, the gantry‑mounted LiDAR volume measurement system from Chongqing Jinyun Robotics helps muck transportation enterprises eliminate settlement conflicts. Simple to install and plug‑and‑play with offline capability, it realizes instant measurement upon vehicle arrival, immediate passage after detection, and traceable data records.
