BOJIN Crane Sensors

In the heavy machinery and construction industry, safety, efficiency, and precision are non-negotiable — especially when it comes to crane operations. One of the most critical components ensuring safe lifting performance is the crane length-angle sensor, often integrated with a moment limiter wire length measurement device to monitor real-time load conditions. These advanced systems help prevent overloading, tipping, and structural failures, making them indispensable in modern crane technology.

At the forefront of this technological advancement stands BOJIN, a leading length-angle sensor manufacturer based in China, known for delivering high-performance, custom engineered sensing solutions that meet global industrial standards. As a trusted high-precision wire length measurement supplier, BOJIN has earned a strong reputation for innovation, reliability, and tailored service across diverse markets.

The Role of Length-Angle Sensors in Crane Safety

Crane operations involve complex dynamics influenced by boom angle, length, load weight, and environmental conditions. A crane length-angle sensor provides accurate, real-time data on these variables, enabling operators to make informed decisions and avoid dangerous situations.

When combined with a moment limiter wire length measurement device, the system calculates the crane’s lifting moment — essentially determining whether the current load exceeds safe operational limits. This integration plays a crucial role in preventing accidents, reducing equipment wear, and improving overall job site efficiency.

From mobile cranes and tower cranes to offshore lifting systems, BOJIN’s sensor technologies are designed to withstand harsh working environments while maintaining exceptional accuracy and response time.

Why Choose BOJIN?

As a China-based manufacturer, BOJIN brings together decades of engineering expertise and cutting-edge production capabilities to deliver top-tier sensor solutions. Their products are widely used in construction, port operations, mining, and industrial automation, serving clients around the world.

What sets BOJIN apart is its commitment to custom engineering. Unlike generic sensor providers, BOJIN works closely with clients to design and manufacture length-angle sensors tailored to specific crane models, operational requirements, and environmental conditions.

Whether you need a compact sensor for small mobile cranes or a multi-axis system for large-scale industrial applications, BOJIN offers scalable, modular solutions that integrate seamlessly into existing control systems.

Advanced Technology for Maximum Precision

Each length-angle sensor developed by BOJIN incorporates high-resolution encoders, digital signal processors, and durable materials built to withstand vibration, moisture, and extreme temperatures. These features ensure long-term stability and minimal maintenance, even under the harshest field conditions.

The wire length measurement devices offered by BOJIN use advanced pulley-and-cable mechanisms or magnetic displacement systems to provide highly accurate readings of the boom extension. These measurements are then transmitted digitally to the crane’s control panel, allowing for instant feedback and automated adjustments if necessary.

All BOJIN sensors are tested rigorously before delivery, ensuring compliance with international standards such as CE, ISO 9001, and RoHS. This dedication to quality ensures that every component not only meets but exceeds industry expectations.

Customization for Diverse Applications

BOJIN understands that no two crane systems are exactly alike. That’s why they offer extensive customization options — from sensor dimensions and mounting styles to output protocols (such as CANbus, RS485, or analog signals). Clients can also request additional features like waterproofing, dust resistance, and anti-corrosion coatings for specialized environments.

This level of adaptability makes BOJIN an ideal partner for original equipment manufacturers (OEMs), crane builders, and aftermarket solution providers who require reliable, high-performance sensing systems tailored to their unique needs.

Global Reach with Local Support

Despite being headquartered in China, BOJIN serves a wide international clientele through a robust distribution network and multilingual technical support team. They provide full documentation, including installation guides, calibration instructions, and troubleshooting resources, ensuring seamless integration and ongoing product support.

Additionally, BOJIN offers OEM/ODM services, allowing businesses to develop branded sensor lines with private labeling, packaging, and user interface customization.

In the demanding world of crane and lifting equipment, precise monitoring and intelligent control systems are essential for both safety and productivity. BOJIN delivers unmatched performance with its crane length-angle sensors and moment limiter wire length measurement devices, setting new benchmarks in accuracy, durability, and smart integration.

As a China-based manufacturer, BOJIN combines technical excellence with custom engineering flexibility, making it the go-to partner for businesses seeking premium sensor solutions at competitive prices. Whether you're building cranes from scratch or upgrading existing fleets, BOJIN provides the tools you need to operate safely, efficiently, and intelligently — one lift at a time.
