Bosch Rexroth hydraulics to turn world’s largest wheel

博世力士樂液壓系統為全球最大摩天輪提供動力

April 2, 2007 - The Great Wheel Corporation recently awarded Bosch Rexroth with the contract to supply the automation systems for the world’s largest look-out wheel in Beijing, China.

4月2日消息——摩天輪公司（The Great Wheel Corporation）最近授予博世力士樂公司一份合約，為位于中國北京的全球最大的觀光摩天輪提供自動化系統。

The 678-foot high wheel will start service in the Chinese capital in time for the 2008 Olympic Games. Bosch Rexroth will provide project engineering, shipment and installation of the complete hydraulic drive and control systems, as well as the automation for the passenger boarding stations.

這個678英尺高的摩天輪將趕在北京2008年奧運會召開之前開始營運。博世力士樂將為該完整的液壓驅動和控制系統提供項目工程、運輸和安裝，以及乘客上落站的自動化系統。

The Great Wheel Corporation chose Bosch Rexroth to supply the technical systems because the drive and control company is a leading supplier of motion platforms, and because of its emphasis on reliability and safety.

摩天輪公司之所以選擇博世力士樂供應這些技術系統，是因為博世力士樂這家驅動和控制公司是運動平臺的領先供應商，以及其對可靠性和安全性的重視。

The Rexroth-designed drive system comprises a powerful, nearly maintenance-free hydraulic power unit. In addition, the company’s hydraulic motors will drive 32 special tires that contact the 648-foot diameter wheel, making it rotate at a constant speed of three times an hour. A fail-safe backup system ensures reliable operation, even if a fault develops in the main circuit. The Rexroth drive concept has already been operating successfully on England’s London Eye, which is currently the largest Great Wheel in Europe.

這個力士樂設計的驅動系統包含一個強大的、幾乎無需維護的液壓裝置。此外，該公司的液壓馬達將帶動32條特制輪箍，而這些輪箍連接到這個直徑為648英尺高的摩天輪，使其以每小時旋轉三次的勻速旋轉。一個自動防故障裝置的后備系統確保了可靠的運轉，即時在主要電路產生了故障。力士樂的驅動設計已經成功地運用于英格蘭的倫敦眼（ London Eye）項目，它目前是歐洲最大的摩天輪。

The 48 capsules on the Great Beijing Wheel each provide space for 40 passengers who can enter and exit while the wheel is turning. Each capsule is equipped with a state-of-the-art audio and visual information system that describes Beijing and the surrounding area, including the Gate of Heavenly Peace in the Forbidden City.

北京摩天輪擁有48個艙位，在摩天輪旋轉的時候每個艙位的空間足夠容納40個乘客進出。每個艙位配備頂級的音頻和視覺信息系統，介紹北京和周邊的情況，包括紫禁城的天安門。

Bosch Rexroth is supplying the automation equipment for the moving boarding stations. The stations will be synchronized with the motion of the Great Wheel, and will be located on either side. To avoid unnecessary stops and starts and the potential loss of inertial energy on the wheel, passengers will board via special cars on a separate track. These cars will then travel alongside to match the speed of the wheel at the bottom of its rotation so passengers can transfer in and out of the cars. As a result, nearly 5,800 passengers per hour will be able to enjoy the fantastic view over Beijing.

博世力士樂正在為移動上落站提供自動化設備。這些上落站將與摩天輪的運動同步，而且分布于摩天輪的兩邊。為了避免不必要的停止和啟動以及可能的摩天輪慣性運動造成的能量損失，乘客將通過一個獨立通道上的專門車輛登上摩天輪。這些車輛屆時將在摩天輪旋轉到底端的時候在旁邊與其同速行駛，以便乘客可以進入或者走出這些車輛。因此，每小時可以讓大約5千8百名的乘客領略北京的迷人風光。

Bosch Rexroth has established itself as global leader in supplying automation systems for complex projects beyond the entertainment segment. For example, in the Chinese market the company has already supplied the stage systems for the China National Grand Theater in Beijing, the locks for the Three Gorges project, and the automation systems for the first ferry terminal over the Qiongzhou Straits, where the ferry terminal systems are capable of resisting typhoon-strength winds.

博世力士樂確立了其作為一個為復雜項目供應自動化系統的全球領導者地位，而不單單在是娛樂領域。比如，在中國市場，博世力士樂為北京的中國國家大劇院提供了舞臺系統，為三峽工程提供了水閘，為瓊州海峽的第一條輪渡鐵路碼頭提供了自動化系統，使該輪渡鐵路碼頭系統擁有抵抗臺風級別大風的能力。

As a drive and control technology supplier, Bosch Rexroth also serves as the general contractor for unique turnkey projects throughout the world.

作為一家驅動和控制技術供應商，博世力士樂在全球也扮演著一些大型全承包項目的總承包商的角色。

Bosch Rexroth AG, part of the Bosch Group, achieved sales of approximately $6.2 billion (4.9 billion Euro) in 2006 with over 29,800 employees. Under the brand name of Rexroth the company offers all drive and control technologies, from mechanics, hydraulics and pneumatics to electronics and associated service. Over 500,000 customers worldwide utilize Rexroth’s unique technological know-how to implement their innovative and future-oriented systems and machine concepts. The global player, represented in over 80 countries, is an extensive supplier of components and systems for industrial and factory automation and mobile applications.
