The frame of a toy crane machine, commonly found in arcades and entertainment centers, is primarily constructed from durable metals to ensure stability and withstand constant use. The most common material is steel, particularly mild steel or powder-coated steel, which provides the necessary strength and rigidity to support the heavy internal mechanisms, prize compartment, and monitor. For lighter or more portable models, aluminum alloy frames are sometimes used, offering a good balance between strength and weight. The frame acts as the machine's skeleton, housing the claw mechanism, control system, and glass or plastic enclosure. This robust metal construction is essential for safety, preventing tipping, and ensuring the machine remains operational through years of play.
