PST presents the Large Capacity 2T-150T Wireless Shackle Load Cell Digital Weight Sensor Alloy Steel IP67 Waterproof 0.03% Accuracy Crane — a robust, precision-engineered solution designed for heavy-duty lifting, industrial weighing, and high-accuracy crane monitoring. This product merges proven mechanical design with advanced digital sensing and wireless communications to deliver a reliable, safe, and easy-to-integrate load monitoring system. Built for demanding environments, the wireless load cell shackle integrates a high-strength alloy steel shackle with an advanced digital load sensor, creating a crane scale solution that meets the strictest accuracy and durability requirements.

Product Overview and Key Features

The PST wireless load cell shackle is available in capacities from 2 tons to 150 tons, covering a wide range of lifting and weighing needs. Each unit is a complete crane scale assembly, combining a shackle-style load-bearing connection with a digital strain-based load sensor and onboard electronics. The core design emphasizes accuracy, safety, and environmental resistance. With IP67 waterproof load sensor protection, the device withstands dust ingress and short-term immersion, making it suitable for outdoor and maritime operations.

Mechanical and Materials Advantages

The shackle body is forged from high-grade alloy steel, heat-treated for maximum tensile strength and fatigue resistance. The alloy steel construction provides superior toughness for repeated lifting cycles and harsh operational impacts associated with crane work. The shackle geometry is optimized to minimize stress concentrations and to ensure uniform load distribution across the load sensor element. Robust pin design and secure locking features guarantee reliable mechanical coupling and safe retention under dynamic loads. The durable coating and sealing methods enhance corrosion resistance, extending service life in industrial, marine, and outdoor settings.

Sensor Technology and Accuracy

At the heart of the product lies a precision digital load sensor that converts mechanical strain into a calibrated digital signal. The sensor utilizes a high-stability strain gauge bridge combined with low-noise amplification and digital conversion. Advanced temperature compensation algorithms and calibration procedures are applied to achieve 0.03% full-scale accuracy. This high precision makes the shackle load cell ideal for applications where regulatory or contractual accuracy is required.

Wireless Communication and Integration

PST’s wireless load cell capability enables real-time data transmission to remote displays, handheld controllers, data loggers, or plant control systems. The integrated wireless module supports long-range reliable communication, simplifying installation and reducing the need for hazardous cables in lifting zones. Wireless connectivity enables multi-point monitoring by sending crane scale data to multiple receivers simultaneously, improving operational visibility across job sites. For integration purposes, the device supports standard output protocols and can interface with commonly used software and data acquisition systems.

Environmental Protection and Durability

The IP67 waterproof load sensor rating confirms full protection against dust and temporary immersion in water, essential for outdoor deployments and adverse weather conditions. Sealing strategies and rugged construction protect internal electronics and sensors from moisture and contaminants. The unit resists corrosion and mechanical wear, making it well suited for port operations, offshore rigging, construction sites, and heavy manufacturing environments.

Safety, Compliance, and Overload Protection

Safety is paramount in lifting applications, and PST’s shackle load cell includes mechanical and electronic features to prevent overload incidents. The structural design adheres to industry safety factors for rigging hardware, while the digital electronics provide overload alerts, peak load capture, and configurable alarm thresholds. The crane scale supports zeroing, tare, and user-defined limits, enabling operators to enforce safe working loads and comply with inspection and certification requirements. The robust design and accurate measurements support inspection workflows, regulatory compliance, and enterprise risk mitigation.

Applications and Industry Use Cases

This product is engineered for a broad range of heavy-duty applications that require accurate load monitoring and reliable field performance. Typical use cases include:

- Crane scale measurement for construction and heavy lifting operations.

- Industrial weighing and load verification for manufacturing and assembly.

- Marine and offshore rigging where IP67 waterproof load sensor reliability is essential.

Installation, Calibration, and Maintenance

PST provides clear installation procedures and calibration services to ensure each wireless load cell shackle performs to specification. Mounting and pinning instructions reduce user error and ensure proper load paths. Calibration can be performed at the factory or on-site using traceable standards, with firmware supporting multi-point calibration to achieve the specified 0.03% accuracy. Routine maintenance focuses on inspection of the alloy steel shackle, pins, and sealing points, as well as periodic functional checks of wireless connectivity and battery or power systems. The design facilitates straightforward replacement of wearable components without specialized tooling.

Innovation and Technical Differentiation

PST’s wireless shackle load cell combines several technical innovations that set it apart in the crane scale market. The integration of a high-accuracy digital load sensor with advanced temperature compensation and digital filtering minimizes drift and improves repeatability. The long-range wireless design reduces installation complexity and enhances safety by eliminating hazard-prone cables. The IP67 waterproof load sensor architecture is optimized for marine and outdoor use, extending the product’s application scope. Material selection and heat-treated alloy steel provide a superior strength-to-weight ratio and longer fatigue life compared to conventional designs.
