The single-car, two-car, three-car, four-car dumpers with independent intellectual property rights and the automatic unloading and marshalling equipment matching with the said dumpers, the 1000t-15000t/h stacker, reclaimer, stacker＆reclaimer and blending stacker＆reclaimer and the 1000 m3-9000m3/h large spreader have reached or approached the advanced level of the world. Successfully supplied stackers, reclaimers, car dumper system and ship loader for Roy Hill Project in Australia.
Cranes:DHHI is the largest enterprise for development and manufacture of crane in China. The products covers various special lifting machineries, such as overhead traveling crane, gantry crane, full-series cranes for metallurgical plant, etc. Among these products, the overhead traveling crane and gantry crane of brand “DCW” are awarded the titles of “China Famous Product”; the 20,000t overhead traveling crane developed and manufactured independently by DHHI set a Guinness world record.
Port Machinery: DHHI has independent intellectual property right for large port machinery and is the largest enterprise for development and manufacture of ship unloader in China. It is capable of producing various port handling machineries, such as 650t~3600t/h grab ship unloader and continuous ship unloader, 500t~18000t/h ship loader, 30t~65t quayside container crane and container gantry crane and 25t~1900t portal crane, etc.
Crankshaft: all types of ship crankshafts covering MAN series above type 50 and Wartsila series above type 52, with a capacity of producing more than 150 crankshafts per year. The China’s first over-sized joint-type crankshaft 11S90ME-C developed and manufactured independently by DHHI achieved significant breakthrough for localization of over-sized crankshaft, and this makes DHHI the first company in China and the fourth company in the world that has the capacity for self development and manufacture of such type of crankshaft.
