We completed the order for double girder overhead crane installation in Pakistan. The order includes 1 set of 15-ton overhead crane and 1 set of 20-ton overhead crane. We spent half a month communicating with the customer about the details of the order. Production and installation are relatively easy parts. In terms of transportation, we ship from Qingdao port in China to Qasim Karcahi port in Pakistan by sea.
As span is 15.75m, in order to fit in container, the main girders will be disconnected and reconnected using high-strength bolts provided by our factory.
