Zhengzhou Yutong Heavy Industries showed not one new crawler but three: the 55t capacity YTQU55, 80t capacity YTQU80 and 160t capacity YTQU160. The cranes have main boom lengths of 52m, 58m and 81m. Longest boom+jib system lengths (in m) are 43+15, 49+18 and 69+31. Counterweight required is 17.5t, 25t and 56t. All three run on Cummins engines; the 55t model has a 128kW engine at 2,100rpm; the other two have a 209kW engine at 2,000rpm. All three cranes have imported speed reducers, motors, pumps, valves and hydraulics. The Henan province-based company launched the cranes this year, and claims to be working on export models.
