What is a CAN BUS System, and What Do Crane Operators Need to Know About It

An engineer at work

Effective communication is essential to maintain and improve crane safety.

In earlier times, crane operators could only rely on hand signals when operating a crane, but today, technology has made it possible for us to streamline crane safety with smarter control units. CAN BUS systems are an advanced, cutting-edge technology that retrieves and send quicker safety signals. Short for Controller Area Network, a CAN BUS system is a central nervous system connected to vehicles through nodes. It’s configured with smart signals that can sense, share, and transfer data between different components.

Modern-day crane equipment, when equipped with CAN BUS System, can ensure extensive efficiency, proven crane control, and optimized safety. Let’s dig deeper and uncover the ABCs of CAN BUS Systems.

A Short History of CAN BUS Systems

The CAN BUS technology isn’t very new. It was developed in the 1980s by a famous German engineering firm called Robert Bosch GmbH. This system has been adopted in multiple industries, including aerospace and manufacturing.

The CAN BUS system offers fast, reliable, and error-free data transmission and is supported by multiple nodes for accuracy maximization. Nodes, the BUS, and differential signals are the three main components of a CAN BUS System. These components work together to help crane operators stay alert and aware of their equipment’s performance.

You can receive the following four different types of signals via CAN BUS technology;

  • Data frame: Carries data between nodes

  • Remote frame: Requests data from another node

  • Error frame: Indicates an error in communication

  • Overload frame: Suspends communication to allow the transmission of a higher-priority message.

The Ultimate Benefits of a CAN BUS System for Your Crane

A CAN BUS System’s ability to transmit signals without wiring or any other hardware component makes it one of the most highly-sought after safety technologies. It’s simple, easy to use, low-cost, and effective. You can install crane load limit and rated capacity indicators with CAN BUS technology to reduce errors, downtime, and repair/emergency costs.

CAN BUS Systems also improve crane operator, rigger, and signaler accessibility by enabling internal diagnostics and troubleshooting frameworks. They fast-track data enablement and provide operators with critical information about real-time crane operational safety.

Moreover, CAN BUS Systems offer superior resistance against external signal-reducing factors. They can work well under electrical disturbances without compromising a crane’s flexibility and safety. You can also use a CAN BUS-loaded LMI-RCI system to receive priority signals and interruption-free data.

Preventing Crane Overloading with CAN BUS Technology

Crane overloading is a critical challenge for crane operation teams, but it can easily be avoided with the right type of crane warning indicators. The RaycoWylie i4500 LMI-RCI system features the CAN BUS technology for easier and more streamlined input and output signals. It has intelligent computing for self-diagnostic detection capability with high-precision audio and visual alarms.
