You get what you pay for. If you want a durable, reliable machine that has replacement parts availability guaranteed any where in the world buy a Cat. If you want a machine that is guaranteed to run while it's being delivered off the lowboy and parts replacement part are virtually nonexistent buy a Chinese machine. Cat's been in this business for 85 years. They know the difference between a deep penetration weld and glue. Heat treated gears are an entire science in itself. Does Sany have a clue? What's Zoomlion know about diesel engine exhaust valve metallurgy? Nothing. Now those machines may be better than a couple dozen Chinese with picks and shovels. Have you seen the picture of them loading a wheel loader bucket with shovels? Priceless.
