The weight limit for prizes in a toy crane machine isn't a single, universal number. It varies significantly based on the machine's model, calibration, and the operator's settings. Typically, the claw's gripping strength is calibrated to handle prizes within a specific weight range, often between 100 grams (3.5 ounces) to 300 grams (10.5 ounces) for standard machines. Operators set this limit to balance profitability with customer satisfaction. A prize that is too heavy may not be lifted at all, while one that is too light might slip from the claw easily. Understanding this can improve your strategy: look for prizes that are compact and have a firm, grippable surface, as these are often within the machine's optimal weight range for a successful grab. The key is to observe the machine's performance over several tries to gauge its effective lifting capacity.
