A Yellow Hydra Main Frame typically refers to the primary supporting structure of a pick-and-carry crane, often called a Hydra crane. This frame is usually made of mild steel and painted yellow for visibility. It's a heavy-duty, all-welded structure that provides a base for the crane's lifting and carrying functions. 

The Hydra Crane Main Frame is a crucial structural element that provides the backbone for crane operations. Engineered for durability and strength, this frame supports various crane components, including the boom, counterweights, and hydraulic systems.
