A box drop tester is a machine with technical specifications like drop height (e.g., 750mm to 1800mm), sample weight capacity (e.g., up to 50kg), and platform dimensions (e.g., 465 x 445 mm), designed to test the durability of packaging by simulating free-fall impacts. Key features include mechanisms for straight and angular drops, manual or motorized operation, and safety features like a locking pin. Drop testers also come with digital height indicators and can offer optional features such as pneumatic systems or customized platforms.
