If your small crane has been in use for some time and you notice it losing strength—meaning it can't lift loads after pausing mid-operation—it can be quite frustrating, especially if you're unsure why. Let me break this down for you. First off, always start by checking the voltage. Low voltage is a common culprit, as it can lead to insufficient motor power. To address this, either adjust the voltage or invest in a reliable voltage tester to monitor it regularly.
Next, consider the condition of the motor. Motors on small cranes tend to degrade or wear out after two or three years of use. If yours seems weak, it might be time to send it back to the manufacturer for repairs or replacement. Overloading is another frequent issue that weakens the motor. Be mindful of the load capacity, and if necessary, opt for a higher-powered motor to prevent such problems. Additionally, you might need to replace the capacitor in the control switch or upgrade to a more robust switch to assist with lifting tasks.
Don’t overlook the importance of the wire rope either. A thicker diameter or longer length can significantly impact performance by increasing the roller’s size, which reduces the motor's efficiency and decreases lifting capacity. If you're experiencing these issues, feel free to reach out for further assistance. Remember, proper maintenance and careful selection of components can go a long way in keeping your crane running smoothly.
