Portal powerChinas rapid economic growth in the past decade has resulted in a big increase in freight traffic through the countrys seaports . Old ports are being expanded and new ports built to handle the large growth in container and bulk cargo traffic all along the Chinese coastline.Chinas port expansion programme has provided a strong boost to the domestic port equipment industry, which has enjoyed a strong increase in demand for port cranes of various types, including container cranes and portal cranes along with bulk cargo handling equipment.State-run China Harbour Engineering (group) Corporation Ltd, established under the ruling State Council, is Chinas largest supplier of port cranes and bulk cargo handling equipment. The organization controls both Shanghai Zhenhua Port Machinery Co Ltd (ZPMC),the worlds largest manufacturer of quayside container cranes, and Shanghai Port Machinery Plant (SPMP), which specializes in the manufacturer of portal cranes and other cranes used in ports along with dry bulk cargo handling equipment.SPMPs main market is China, although the company is looking to expand its overseas sales. Although less well known than its associate ZPMC, SPMP also operates large manufacturing facilities, and is due to move part of its production shortly to Changxing Island near Shanghai where ZPMC already operates a large container crane fabrication plant.Portal and other harbour cranes are SPMPs major production item. During the past two years, the corporation has won contracts for 145 portal cranes from port authorities throughout China, both from new ports under construction and ports undergoing expansion.In recent years, SPMP has also supplied portal cranes to the United States, Iraq,and Myanmar.The port Rangoon of Myanmar in has purchased a 47m,40t portal crane while BIW of the United States has purchased three cranes-15t,150t, and 300t portal cranes. Elsewhere, SPMP has supplied 12 portal cranes to several ports in Iraq since the end of the Saddam regime. In China, SPMPs recent major orders for portal cranes include eight 40t, 45m radius cranes for Tianjin Overseas Mineral Terminal, while Yan Tai Port Bureau in Guangdong in southern China has purchased six 40t, 45m radius cranes. Other large orders include seven 10t, 25m radius cranes for Zhenjiang Port Group and an order of 1025t, 33m radius cranes from Fangcheng Port Bureau, while the Yingkou Port Group has ordered 1325t,35m radius cranes along with two 40t, 44m radius port cranes.MANY CRANES BUILT TO ORDERSPMP also supplies other cranes used in ports and harbours, many of which are built to order for clients. Quayside container cranes have been supplied to a number of foreign clients including Bangkok Port in Thailand, Kaohsiung Port in Taiwan, and Port of Vancouver in Canada. In China, SPMP has supplied quayside container cranes to Shanghai Port, Tianjin Port, Yin Kou Port, Yan Tai Port and others. The company also supplies rubber-tyred container gantry cranes to domestic and overseas clients.Customers for other cranes used in ports include Guangzhou Port in Guangdong, which purchased a 25t floating crane while Zhonggang Port has bought two double trolley 125/63t gantry cranes, along with a700t overhead crane, In 2003 Zhonggang Port awarded a contract to SPMP for a 2,600t floating crane, whichi is the largest crane the company has made in recent years.Other customers include Zhongyuan Nanytong Shipyard of Jiangsu Province has purchased two 300t goliath cranes for use in its shipyard, while Shanghai Waigaoqiao Shipyard uses two of SPMPs 600t goliath cranes for its shipbuilding operations. SPMP has two factories. The Shanghai plant employs 2,000 workers while a factory in Jiangsu Province employs 1,500 workers. The combined total of 3,500 workers includes 800 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 companys existing plot of land is part of a riverside area earmarked by the Shanghai Expo in 2010. SPMPs 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 co-operate more in bidding for projects in future. Both companies are expected to retain their individual manufacturing capability, however, with precise details of future co-operation still some way from being finalised.Meanwhile, SPMP associate company ZPMC is strengthening its position as the worlds largest manufacturer of ship-to-shore container cranes, supplying slightly more than half the annual international container crane market. In addition to operating four crane production complexes for its crane manufacturing and other businesses.ZPMCs full range of products includes quayside container cranes, rubber-tyred gantry cranes, bulk material ship loaders and unloaders, bucket-wheel stackers and reclaimers, portal cranes, floating cranes, and engineering vessels. The company has also diversified into manufacturing other large steel structures including large steel bridges.ZPMC EXPANDING PRODUCTIONZPMCs 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 rubber-tyred gantry cranes to customers worldwide and had orders in hand to deliver 308 rubber-tyred gantry cranes to customers in 2006.ZPMC is expanding production facilities in expectation that the volume of orders will grow in future. The company owns four crane production complexes in Shanghai and the surrounding area at Jiangyin, Changzhou, Zhangjiang and Changxing Island.The Changxing production site, which was completed in 2001, covers one million sq m, and has a 3.5km coastline. The facility is capable of manufacturing 160 quayside ship-to-shore container cranes each year along with 300 rubber-tyred 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 become its largest production centre.港口起重机中国经济在过去的高速增长已经大幅增加了本国港口货流量，以至于不断扩大老港口以及不断修建新的港口以应对快速增长的集装箱业务以及大宗货物的流通。中国的港口扩展进程对本国港口装备行业的发展产生了强烈的刺激，这一进程强烈需要大量的各种各样的港口起重机的迅猛增加，包括集装箱起重机、桥门式起重机以及其他能够处理散料货物的装卸设备。由国资委掌控的中国港口工程集团有限公司是中国最大的港口起重机和散料装卸设备的供应商。该集团包括世界最大的港口集装箱起重机生厂商振华港口机械有限公司（ZPMC）和精于生产用于港口的桥门式起重机以及干散货物的装卸设备的上海港口机械厂（SPMP）。上海港口机械厂主要市场是中国本地，虽然它在寻求扩大海外销售。尽管它没有同行振华港口机械有限公司出名，上海港口机械厂拥有很多的大型生产设施，它计划不久将一部分生产线转移到上海附近的长兴岛。振华港口机械有限公司已经在那里建立了一个大型集装箱起重机组装厂。上海港口机械厂主要的生产项目是桥门式起重机和其它用途的港口起重机。在过去的两年里，该公司已经获得了来自全国港务局的的145份桥门式起重机的合同，这其中包括正在建设的新港口和正在扩张的港口。最近几年，上海港口机械厂已经向美国，伊拉克以及缅甸提供桥门式起重机。缅甸的仰光港口购买了一座跨度为47米，起重量为40吨的桥门式起重机，然而美国的BIW购买了三台起重量分别为15t,150t, 和 300t起重机。另外，自从萨达姆下台后上海港口机械厂已向伊拉克的一些港口提供了12台起重机。在中国，上海港口机械厂最近的主要订单是桥门式起重机，这其中包括天津海外矿产航运码头的8台起重量为40t，回转半径为45m的起重机，然而，位于中国南部的广东盐田港务局已经购买了6台这样的起重机。其它一些大的订单包括镇江港务集团的7台起重量为10t，回转半径为25m的起重机和防城港务局的10台起重量为25t，回转半径为33m的起重机，而营口港务局已经13台起重量为25t，回转半径为35m和2台起重量为40t，回转半径为44m的桥门机。许多起重机按照订单在建上海港口机械厂也提供港口和海湾其它用途的起重机，这些大多数按照客户的要求建造。它已经向许多国外客户提供岸边集装箱起重机，这其中包括泰国的曼谷港，台湾的高雄港和加拿大的温哥华港。在中国国内，该公司已向上海港，天津港，烟台港以及其他的一些港口提供岸边集装箱起重机。该公司也向国内外客户提供轮胎式龙门起重机。订购其它港口起重机的公司包括广东的广州，它购买了一台25t的浮吊，而中港港口已购买了两台125/63t双小车龙门起重机和一台700t的桥式起重机。2003年，中港港口与上海港口机械厂签订一台2600t的浮吊合同，这是该公司近些年做的最大吨位的起重机。其它的一些用户包括江苏省的中原南通造船厂，它已经购买了两台300t用于船坞的戈利亚特起重机，而上海外高桥船厂已将上海港口机械厂的两台600t戈利亚特起重机用于船舶建造中。上海港口
