Caterpillar unveils more tech upgrades

Machinery giant Caterpillar Inc has been striving to better satisfy customer needs in China by launching a smart watch along with a dozen new excavators, executives said.

At the ongoing Bauma China International Trade Fair, which is being held in Shanghai until Friday, the US firm has introduced a number of next-generation excavators to showcase technology advances, including reductions in fuel consumption of as much as 15 percent in some applications. The expo is China's largest trade show in the construction machinery industry.

Thomas Pellette, Caterpillar group president for construction industries, said the move aims to better address customer needs, and help users work "more effectively, efficiently, safely and sustainably."
