Understanding Crane Load Moment Limiters

Crane load moment limiters are critical safety devices used in cranes to prevent overload and ensure safe operation. These limiters work by monitoring the crane’s load and moment (the product of the load and its distance from the crane’s pivot point) and alerting the operator or automatically stopping the crane if the load exceeds a predetermined limit.

The Importance of Load Moment Limiters in Crane Safety

The importance of load moment limiters cannot be overstated. Overloading is a common cause of crane accidents, which can result in significant damage, injury, or even loss of life. By accurately measuring the load and its moment, these devices help prevent such accidents, ensuring a safer working environment for operators and those around the crane.
