Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Overload Monitoring & Alert System: Equipped with a digital display and "Warn" function, the WTZ-A100N provides real-time weight measurement in tons and triggers alarms when loads exceed safe thresholds, ensuring crane safety.
  • Multi-Brand Compatibility: Designed to work with major crane brands (Sany, Terex, Liebherr, Hitachi, etc.), this load cell indicator serves as a universal overload protection solution for construction machinery.

Key features

  • 1. Corrosion-Resistant Industrial Design

    • With a rugged, corrosion-resistant metal body and dust/water-resistant connectors, you can ensure reliable operation in harsh industrial environments. The protective front panel and rubber-sealed ports outperform basic plastic enclosures*, providing long-term durability.

  • 2. Intuitive Button-Based Interface

    • With a clear digital display and dedicated "Normal," "Warn," and "Control" function buttons, you can adjust settings and monitor weight thresholds quickly. The LED indicators simplify operation compared to models with complex menu systems*.

  • 3. Precision Load Monitoring

    • With real-time tonnage display and adjustable measurement sensitivity, you can achieve ±0.5% accuracy for crane overload protection. This outperforms standard analog gauges* to prevent equipment damage and safety risks.

  • 4. Multi-Brand Compatibility & Customization

    • With pre-configured compatibility for Sany, Terex, and other leading crane brands, you can install this limiter without costly modifications. The customizable warning thresholds also adapt to diverse operational needs*, unlike one-size-fits-all systems*.

  • 5. Safety-Certified Compliance

    • With CE certification and integrated overload warning alarms, you can meet strict industrial safety standards. This ensures legal compliance and reduces workplace accidents compared to uncertified alternatives*.

Supplier's note

  1. Three Technical Breakthroughs:

    • CE Certification: Ensures compliance with EU safety standards for global deployment.
    • Customizable Thresholds: With adjustable warning limits, users can tailor safety protocols to specific crane capacities.
    • IP69K Durability (Pro Model): Triple the ingress protection of standard models, enabling use in extreme environments like mining or marine operations.

  2. Optimal Version Selection:

    • Base Model: Ideal for standard cranes in controlled environments (e.g., warehouses) requiring basic overload protection.
    • Advanced Model: Best for mid-sized construction sites needing multi-level alerts and wireless connectivity for remote monitoring.
    • Pro Model: Designed for heavy-duty applications (e.g., offshore cranes) where extreme durability and ultra-precise measurements are critical. With its IP69K rating, it withstands harsh chemicals and high-pressure washdowns.

*Pro Model’s ±0.1% precision exceeds industry benchmarks by 30%, ensuring minimal errors in high-stakes operations.
