A limiter for a Tower Crane is a safety device that is installed to prevent the crane from operating beyond its maximum load capacity or from moving beyond its designated working area. It typically consists of sensors, control systems, and alarms to ensure safe operation.

The load limiter is designed to monitor the load being lifted by the crane and automatically stop the crane's movement if the load exceeds the specified limit. It helps prevent overloading, which can lead to structural failure or accidents.
The radius limiter is used to restrict the crane's movement within a specific working area. It ensures that the crane does not extend beyond its designated radius, preventing it from colliding with nearby structures or obstacles.
Both types of limiters are essential safety features in tower cranes to protect workers, equipment, and the surrounding environment. They help ensure that the tower crane operates within its safe working limits and minimize the risk of accidents or damage.
