Function:

Proximity switches in cranes are an important safety and control device, and their main roles include the following:
1. Position detection and limit control
The proximity switch detects the end limit positions of the crane and ensures that the crane operates within the preset safety limits. When the crane approaches or reaches the limit position, the proximity switch will send out a signal to stop or change the direction of the crane's movement, so as to avoid safety accidents caused by over-travelling.
2. Safety Protection Function
The proximity switch can monitor the critical position of the crane in real time, such as the limit position of the hook and boom, to ensure that the crane operates within the safety range. For example, the inductive safety proximity switch PSENini can be used to detect the current position of the crane and work with the safety controller to ensure the safe movement of the crane.
3. Speed monitoring and precise positioning
Proximity switches can be used to detect the speed and position of a crane's rotating or moving parts for precise control. For example, in turntable position detection, proximity switches can ensure that the crane is in a specific position for processing or operation.
4. Improved operational efficiency and reliability
The non-contact design of the proximity switch reduces mechanical wear and tear, increasing equipment life and reliability. At the same time, its quick response capability can significantly improve the crane's operational efficiency.
5. Adaptable to harsh environments
Proximity switches are usually waterproof, shockproof, corrosion-resistant, etc., and can operate stably in harsh operating environments. For example, some proximity switches can be protected up to IP68/IP69, which is suitable for applications with high hygiene and environmental requirements.
6. Reduced maintenance costs
The contactless design of proximity switches reduces wear and tear on mechanical parts, reducing maintenance frequency and costs. At the same time, their long life and stability reduce equipment downtime.
In summary, proximity switches not only play an important role in safety protection in cranes, but also improve operational efficiency and equipment reliability, making them an indispensable safety and control device for modern cranes.
