Operating a toy crane machine continuously without breaks can lead to overheating, which may damage internal components and pose safety risks. While manufacturers' specifications vary, a general rule is to avoid running the machine for more than 4 to 6 hours continuously in a controlled environment. For high-traffic locations, it's advisable to implement a cooling period of 30-60 minutes after every 3-4 hours of operation. Key factors affecting heat buildup include ambient temperature, machine quality, and claw mechanism intensity. Modern machines often have built-in thermal protection, but proactive management is crucial. Regularly check ventilation fans, ensure clear air vents, and monitor for unusual noises or smells. Implementing scheduled downtime not only prevents overheating but also extends the machine's lifespan and ensures consistent performance for players. Always consult your specific model's manual for manufacturer-recommended guidelines.
