Preventing a toy crane machine from tipping over when a child leans on it is crucial for safety. First, ensure the machine is placed on a perfectly flat, level, and non-slip surface. Many models come with an anti-tip base or adjustable feet—use them to maximize stability. If not included, you can secure the base to a heavy, sturdy platform or low-profile furniture using brackets. Distributing weight evenly inside the machine, such as by placing heavier plush toys or prizes at the bottom, lowers the center of gravity. Always supervise play and teach children not to climb, hang, or apply excessive force to the machine. Regularly check and tighten all screws and joints. For added security, consider positioning the unit in a corner or against a wall (while ensuring ventilation) to limit access from unstable sides. These simple steps significantly reduce tipping risks, creating a safer play environment.
