Extract exactly the two yellow hydraulic railway lifting cranes from the reference photo (the ones with articulated arms, hydraulic pistons, vertical telescopic booms and lifting hooks at the bottom, mounted on U-shaped base supports). Keep only the two cranes on the left side of the original photo. They must appear large, life-size and imposing, filling most of the frame. Background is a dark grey industrial concrete floor with slight texture, like a real workshop. The cranes are bright yellow, heavy-duty. Shot from eye level or slightly low. Professional industrial product photography. No miniature effect. No text, no people.
