A gait-model shovel is seen during the ongoing China-Eurasia Expo in Urumqi, northwest China's Xinjiang Uygur Autonomous Region, Sept. 2, 2011. The all-terrain shovel, designed and made by China's leading heavy machinery maker XCMG, is equipped with "walking wheels" which enable it to work under unfavorable circumstances like swamp and steep slope.
