⚖️ Capacity & Load Performance
Heavy‑duty crane scales are designed to weigh large suspended loads with precision, from mid‑range capacities up to multi‑ton industrial applications:
- Capacity Range: Models available from 500 kg up to 20 tons (20,000 kg) depending on requirements.
- Division/Resolution: Typical increments like 1 kg (for 1–5 ton models) and 5 kg (for 10 ton and above) allow accurate measurement relative to capacity.
- Accuracy Standard: Many industrial models conform to OIML Class III precision standards.
- Safe Load Limit: Designed to handle ~125% of rated capacity safely during normal operation.
- Ultimate Overload Tolerance: Can withstand up to ~400% of rated load without permanent damage.
🖥️ Display & Units
- Digital Display: Large LED or backlit LCD screen for easy reading from a distance or in low light.
- Weight Units: Switchable between kg and lb (some models also support N or ton units).
- Stable Reading Time: Most models settle within ≤10 seconds for reliable measurement.
🧠 Weighing Functions
Industrial crane scales typically include multiple smart functions for accurate and efficient measurements:
✔ Tare / Net Weight: Subtract the weight of attachments or containers.
✔ Zero & Auto Zero Tracking: Maintains a stable baseline before weighing.
✔ Hold / Peak Hold: Locks stable weight for recording.
✔ Unit Conversion: kg ↔ lb selectable.
✔ Overload & Low Battery Alerts: Warns operators before exceeding capacity or when battery is low.
✔ Accumulation & Calibration Options: Some models allow cumulative weighing and calibration settings.
🔋 Power & Operation
- Battery Powered: Most heavy‑duty models include a rechargeable battery pack (commonly 6 V/7–10 Ah) for cordless industrial use.
- Battery Life: Typically >80–100 hours continuous use per charge.
- Auto Power‑Off & Power Saving: Features to conserve battery when idle are common.
🛠️ Construction & Durability
Heavy‑duty crane scales are built for rugged industrial environments:
- Housing Material: Tough aluminum alloy or die‑cast housing for impact resistance and long service life.
- Load Cell: High‑strength alloy steel load cell for accurate tension measurement under heavy load.
- Hook & Shackle: Reinforced steel or galvanized safety shackle and hook with safety latch.
- Operating Temp Range: Typically from −20 °C to +50 °C for broad industrial usability.
- Remote Control (Optional): Some models include infrared or wireless remote control for safe operation from a distance.
