Product DescriptionProduct Introduction of Hook ScaleThe hook scale is a high-precision weighing device specially designed for suspended weighing scenarios. By integrating the weighing sensor with the hook structure, it can be directly hooked onto cranes, overhead cranes, forklifts and other lifting equipment to achieve "dynamic weighing in the air" of various goods. It breaks the fixed weighing limitations of traditional platform scales and floor scales, and is widely used in industrial production, logistics and warehousing, ports and docks, construction and other fields. It is a key device for improving weighing efficiency and ensuring operational safety.Core application scenariosThe flexibility of hook scales makes them suitable for weighing needs in multiple industries. The core application scenarios include:Industrial production processes: They are used for loading and unloading weighing of raw materials (such as steel, aluminum, and chemical raw materials) in workshops, as well as for weight verification of semi-finished and finished products, to prevent production losses caused by weight deviations. Please provide the text you would like translated.In the field of logistics and warehousing: During the process of goods entering and leaving the warehouse and container loading and unloading, palletized goods and large items can be weighed directly without the need to be moved to a fixed scale, significantly enhancing the efficiency of loading and unloading. Please provide the text you would like translated.Port terminal operations: For bulk cargo (such as coal, ore, and grain) handled by ships, the weight of each single hook of cargo is measured in real time to assist in calculating the total loading and unloading volume, while monitoring whether the load meets the ship's load-bearing requirements. Please provide the text you would like translated.In the construction site, the weights of the reinforcing bars, cement, prefabricated components and other building materials lifted by tower cranes are measured to prevent the risk of tower crane overturning due to overloading and ensure construction safety. Please provide the text you would like translated.Special environment operation: Some hook scales with explosion-proof (ATEX/IECEx certified) and high protection (IP67/IP68) features can be used in chemical explosion-proof workshops, outdoor rain and snow environments, and high-temperature smelting scenarios, meeting the demands of complex working conditions.Core advantages: Efficiency, accuracy, and safety1. Dynamic weighing, doubling efficiencyNo need to rely on a fixed scale body. Weighing can be completed during the lifting of goods, eliminating the repetitive process of "transport - weigh - transport" again. Especially for large and heavy goods, the operation efficiency can be increased by more than 50%. Some devices support continuous weighing mode, suitable for the rapid measurement of bulk goods.2. High-precision measurement, reliable dataEquipped with high-sensitivity alloy steel / stainless steel weighing sensors, the accuracy grade can reach OIML III (error ≤ 0.1%), with the smallest division value of 0.1kg, meeting industrial-level measurement standards. At the same time, it has automatic zero tracking and temperature compensation functions to avoid accuracy deviations caused by environmental temperature changes and slight shaking.3. Multiple safety protections, reducing risks? Overload protection: When the load exceeds 105% of the rated range, it triggers an audible and visual alarm; when it exceeds 120%, the weighing function is automatically cut off to prevent sensor damage.? Structural safety: The hook is made of forged steel in one piece, with high tensile strength. Some products have passed the static load test of 2 times the rated load. The shell is mostly made of carbon steel or 304 stainless steel, which is impact-resistant and corrosion-resistant.? Operational safety: Equipped with backlit LCD / high-brightness LED display, the reading can be clearly seen from a distance of 5-10 meters, avoiding the need for operators to approach the lifting area and reducing safety hazards.4. Intelligent functions, suitable for digital managementMainstream hook scales support connection methods such as Bluetooth 5.0, Wi-Fi, and RS485, allowing real-time transmission of weighing data to computers, PLC systems, or cloud platforms for data storage, report generation, and remote monitoring. Some devices support "tare" and "peak hold" functions (capturing the maximum weight during the lifting process), as well as unit switching (kg/lb/t), adapting to different regional measurement habits.Product ParameterAttribute CategoryAttribute NameDescription/DetailsExample ValuesCore Capacity & AccuracyMaximum CapacityThe maximum weight the crane scale can safely measure without damage.500 kg, 1 ton, 5 tons, 20 tons, 100 tonsMinimum CapacityThe minimum weight the crane scale can accurately detect.1 kg, 5 kg, 10 kg, 20 kgAccuracy ClassCompliance with international accuracy standards (e.g., OIML, NTEP).OIML III, NTEP Class III, ISO 9001 CertifiedDivision Value (d)The smallest incremental weight unit the scale can display.0.1 kg, 0.5 kg, 1 kg, 5 kgDesign & ConstructionMaterial (Load Cell & Housing)Materials used for critical components (load cell: sensitive; housing: durable).Load Cell: Alloy Steel/Stainless Steel; Housing: Carbon Steel/Stainless Steel 304Protection Rating (IP Rating)Resistance to dust, water, and harsh environmental conditions.IP65 (dust-tight, water jets), IP67 (dust-tight, temporary submersion), IP68Dimensions (L x W x H)Overall physical size of the crane scale (excluding hooks).300mm x 200mm x 150mm, 500mm x 350mm x 280mmNet WeightWeight of the crane scale itself (affects lifting efficiency).15 kg, 30 kg, 80 kg, 200 kgHook Type (Top & Bottom)Design of upper (for lifting device) and lower (for load) hooks (strength & compatibility).Top: Eye Hook/Swivel Hook; Bottom: Clevis Hook/Grab Hook; Material: Forged SteelDisplay & OperationDisplay TypeTechnology used for weight readout (visibility in different lighting).LCD (backlit), LED (high-brightness), OLEDDisplay ResolutionClarity of the weight display (number of pixels or digits).7-segment LED (0.5" digits), 128x64 LCD screenOperating ButtonsFunctions supported by physical or touch buttons.Power, Tare, Zero, Unit Switch (kg/lb), Hold, Peak Value, MenuOperating Temperature RangeTemperature range the scale can operate normally without accuracy loss.-20°C to +60°C (-4°F to +140°F), -30°C to +80°C (-22°F to +176°F)Power & ConnectivityPower SourceType of power supply for the scale.Rechargeable Lithium-Ion Battery (7.4V/5000mAh), AC Adapter (100-240V AC)Battery Life (Continuous Use)Duration the scale can run on a full battery charge.8-12 hours, 15-20 hours, 24+ hoursCharging TimeTime required to fully charge a depleted battery.3-4 hours, 5-6 hoursConnectivity OptionsWireless or wired connections for data transfer or remote control.Bluetooth 5.0, Wi-Fi (IEEE 802.11 b/g/n), RS485 Serial Port, USBFunctionality & SafetyTare FunctionAbility to subtract the weight of containers/pallets to measure net load weight.Yes (manual/auto tare), Tare Range: 0 - Full CapacityPeak Hold FunctionAbility to capture and display the maximum weight reached during lifting.Yes, Auto Reset (10s/30s) or Manual ResetOverload ProtectionMechanism to prevent damage when load exceeds capacity.Audible/Visual Alarm (at 105% of capacity), Auto Shutdown (at 120% of capacity)Unit of MeasurementWeight units the scale can display.kg (Kilogram), lb (Pound), t (Ton), g (Gram)Certification & ComplianceSafety CertificationsCertifications ensuring compliance with global safety standards.CE (EU), FCC (US), CSA (Canada), ATEX (Explosive Environments), IECExQuality CertificationsCertifications for manufacturing quality and performance.ISO 9001 (Quality Management), ISO 14001 (Environmental Management)FAQWhat are the common types of hook scales?WTWS hook scales are generally divided into direct-reading hook scales, wireless hook scales, portable hook scales, and high-temperature resistant hook scales.
