Where is the master switch located?

The master switch is an essential component in crane operation as it controls the power supply to various systems of the crane. In many crane models, the common placement of the master switch on the left side of the engine cowling is strategic, allowing for easy access and visibility for operators and maintenance personnel. This location enables a quick disconnect of power, which can be crucial for safety during maintenance or emergencies.

Additionally, situating the master switch on the left side engine cowling helps in preventing accidental activation of systems while ensuring that operators can conveniently reach it from ground level or from the operator's seat. This setup aligns with the best practices in equipment design, promoting operational safety and maintenance efficiency. For these reasons, this location is often standardized in crane designs, making it the correct choice in this scenario.
