Buying a used toy crane machine can be a great investment for your business or home arcade, but it's crucial to know what to look for. First, thoroughly inspect the physical condition. Check the cabinet for major dents, cracks, or water damage. Examine the glass or plexiglass for deep scratches that would obscure the view. Next, test the core mechanics. Power it on and run multiple cycles of the crane. Listen for unusual grinding or whining noises from the motor or gears. Watch the claw's movement; it should drop, close, and retract smoothly without jerking. Ensure the claw's grip strength is adjustable and functional. Don't forget the interior! Look for signs of previous repairs, rodent damage, or corroded wiring. Ask the seller about its history: How old is it? Why are they selling it? Has it been in a commercial setting? For pricing, research the average market value for the specific make, model, and age. A machine priced significantly lower than average often indicates hidden problems. Factor in potential repair costs for common issues like joystick replacement, motor service, or cosmetic touch-ups. Finally, ensure all necessary keys, manuals, and adjustment tools are included. A good deal isn't just the lowest price; it's a fair price for a machine that is operational, repairable, and comes from a transparent seller. Taking the time for a careful inspection will save you money and headaches in the long run.
