By 1874, a steam locomotive had been built for use in construction work on the Shanghai and Woosung Railway, and it was the first locomotive to run in China. Subsequent developments were in turntables, traversers, locomotive hoists, hydraulic buffer stops and the various types of cranes, including steam and, later diesel breakdown cranes, some with lifting capacities of more than 100 tons. The company made the first ever mobile hydraulic crane and became a leader in crane technology.
