Zhengzhou Hengliang Tech Co., Ltd. hengliang_electronic@aliyun.com 86-180-39541010
Here is Ganzi, Sichuan, a very beautiful place in Southwest of China!
We have fully finished installation, pavement embedding and system commissioning of quartz weigh-in-motion systems, hand-in-hand with our system integration partner.
Severe site challenges in high-altitude plateau
Located at average altitude over 3,200m, the site faces extreme plateau operating conditions:
Wide temperature swing from -15℃ to 30℃, severe freeze-thaw cycles all year round
Complex mountain geology, frequent groundwater seepage & slippery road surface
Heavy engineering truck & mineral transport flow, frequent overloaded impact
Short valid construction window, harsh oxygen-deficient working environment
Core advantages of quartz WIM reflected in plateau operation
✅ Near-zero creep & tiny zero drift, only annual calibration required, greatly cutting plateau maintenance cost
✅ Stable ±5% total weight accuracy across full speed, no obvious precision loss under high-speed heavy trucks
✅ Thin embedded structure, small pavement damage, short construction period suitable for mountain road limited traffic closure
✅ Strong low-temperature signal stability, anti-freeze waterproof structure adapts to long winter plateau climate
✅ Clear axle pulse signal, reliable identification of multi-axle heavy haul trucks for non-site overload law enforcement
