SHANTUI Bulldozer SD22 Bulldozer

Just as leading brand names have become substitutes for product names around the world, savvy Chinese often simply say ‘Shantui’ when they talk about bulldozers.

It makes sense: Shantui is the King of the Hill in China when it comes to the muscular machines that powered much of China’s phenomenal quarter century-long construction boom. For decades, Shantui has led China’s bulldozer market in most every category of market and volume share.

Today, Shantui is well on its way to becoming synonymous with ‘bulldozers’ well beyond the borders of China, delivering the mechanical muscle to construct great walls, not to mention dams, power plants, housing, factories, hospitals, buildings, offices, ports—you name it!—just about everywhere on the planet people put mechanical muscle to work to build structures or tear them down.
