Standing on the exterior wall of the castle, Zhang Tie watched a constructor operating a railed trailer to push a huge set of steam-driven boilers from a faraway material center to the foot of the gate of castle. The rail crane slowly lifted the set of steam-driven boilers in the air.
Safety hats on heads, some constructors of Long Wind Business Group fastened some wire cables onto the hanger plate to keep the balance of the huge machine while communicating loudly with the operators of the railed crane on the high platform.
"Slowly, slowly, a bit left, right, a bit left, okay, keep lifting, keep lifting, right..."
