【正文】 00 technical and management staff involved in designing, developing, and building portal and other cranes along with dry bulk cargo loading and unloading equipment.Currently, SPMP is preparing to vacate its Shanghai factory site as the pany’s existing plot of land is part of a riverside area earmarked by the Shanghai Expo in 2010. SPMP’s Shanghai factory will close at the end of 2006, and move to a new site on nearby Changxing Island.“The new factory will be much bigger than the present plant,” Li said. “Phase 1 will be ready for us when we move at the end of 2006.”In addition to moving the Shanghai factory to a new site, SPMP expects future business operation with ZPMC.Officials at China Harbour Engineering (Group) Corporation are understood to have told SPMP of plants for SPMP and ZPMC to cooperate more in bidding for projects in future. Both panies are expected to retain their individual manufacturing capability, however, with precise details of future cooperation still some way from being finalised.Meanwhile, SPMP associate pany ZPMC is strengthening its position as the world’s largest manufacturer of shiptoshore container cranes, supplying slightly more than half the annual international container crane market. In addition to operating four crane production plexes for its crane manufacturing and other businesses.ZPMC’s full range of products includes quayside container cranes, rubbertyred gantry cranes, bulk material ship loaders and unloaders, bucketwheel stackers and reclaimers, portal cranes, floating cranes, and engineering vessels. The pany has also diversified into manufacturing other large steel structures including large steel bridges.ZPMC EXPANDING PRODUCTIONZPMC’s cranes and other products are in use at over 150 shipping terminals in 37 countries and regions worldwide. By the end of December 2005, ZPMC had supplied 705 quayside container cranes, and had orders in hand to deliver another 128 quayside container cranes in 2006. In addition, at the end of 2005 ZPMC had delivered 1,148 rubbertyred gantry cranes to customers worldwide and had orders in hand to deliver 308 rubbertyred gantry cranes to customers in 2006.ZPMC is expanding production facilities in expectation that the volume of orders will grow in future. The pany owns four crane production plexes in Shanghai and the surrounding area at Jiangyin, Changzhou, Zhangjiang and Changxing Island.The Changxing production site, which was pleted in 2001, covers one million sq m, and has a coastline. The facility is capable of manufacturing 160 quayside shiptoshore container cranes each year along with 300 rubbertyred gantry cranes and 200,000 metric tons of large steel bridge structures.Plans call for a futher 3 million sq m of land to be reclaimed at Changxing, which ZPMC will develop to bee its largest production centre.Korea looks inward In a fragmented global port crane industry, Korean manufacturers are being forced to look for more business in their domestic markets South Korea’s container crane and port crane equipment manufacturing industry has bee more focused on the domestic market in recent years as manufacturers have faced tough price petition from ZPMC of China in major foreign markets. The problem is the same as that faced by other port crane manufacturers around the world, none of which account for more than about an 8% share of the world container crane market. As well as ZPMC, petition from European and Japanese equipment suppliers is also strong, both for quayside container cranes and for rubbertyred gantry crane contracts. While South Korean firmsincluding Hyundai Heavy Industries, Samsung Heavy Industries, Doosan Heavy Industries, and Hanjin Heavy Industries – continue to bid for international contracts, winning large orders has bee increasingly rare.
