Zoomlion Helps Build Seven Wonders of the Modern World

“We are very excited and we are honored to be the supplier of equipment for this century project. We came to the project six years ago and have experienced the test of a long construction period. We have achieved some results. Our equipment is still in Hong Kong. The Zhuhai-Macao Bridge is finally ready for opening," said the relevant person in charge of Zoomlion.

Over seven years of construction, the Hong Kong-Zhuhai-Macao Bridge is not only the longest cross-sea bridge project in the world, but also the longest-spanned, most-invested and most difficult-to-construction cross-sea bridge project in the history of Chinese construction. It connects Hong Kong, Zhuhai and Macau. Three places, a total length of 55 kilometers. The equipment manufacturing company Zoomlion began with the construction of the Hong Kong-Zhuhai-Macao Bridge, and has built more than 20 high-end equipment depth-built bridges for the pumping, shipyards, pump trucks, tower cranes, and all-terrain cranes.

Among them, the harder construction section of the Hong Kong-Zhuhai-Macao Bridge is an artificial island near the Hong Kong airport. The height of the bridges in the construction period of the artificial islands has changed, and it is in the turning area, and the construction difficulty has greatly increased.

“Initial construction of artificial islands, more than 10 units of Zoomlion’s concrete equipment entered the field to help open up the construction. The pumping and matching of the ship's distribution machine mainly assisted the concrete pouring of Hong Kong section piers. Since then, several pump trucks have joined the Hong Kong section to connect the land roads. The construction of concrete piers for bridge piers."

In the later period, the construction of an artificial island deck in Hong Kong can not be separated from the deep participation of Zoomlion crane products. It is understood that the artificial island construction section bridge itself is not a horizontal but inclined at a certain angle, and the stability and fretting performance of lifting requirements are extremely stringent. In addition, it also has a strict requirement. Because it is adjacent to the Hong Kong International Airport, air traffic control at airports has severe restrictions on electromagnetic interference.

After many comparisons, the customer finally chose Zoomlion T320-16 tower crane and QAY500 all-terrain crane.

According to the person in charge of the customer, the maximum lifting capacity of the T320-16 tower crane is 16 tons, and the maximum working range is 80 meters, which provides a guarantee for the safe and rapid positioning of the materials required on the project site.

The Zoomlion QAY500 all-terrain crane has a maximum lifting capacity of 500 tons and is responsible for hoisting deck concrete components with a weight of 80-140 tons. “The QAY500 crane uses the main arm condition, the arm length range is 27 meters/33 meters, the lifting range is within 20 meters, and the lifting height is 6-20 meters. The average installation of a component is about 1-2 hours. It should be said that the speed is very fast. "The person in charge of the customer said.

The data shows that QAY500 has entered the market since the end of November 2016. It has been working safely for more than 1,000 hours and installing over 20,000 tons of concrete blocks for bridges. It can be said that it is a true “Hercules”. According to reports, it is expected that the QAY500 will lift nearly 90,000 tons of heavy loads when the project is completed.

In the artificial island project, several Zoomlion cranes and all-terrain cranes are responsible for “playing together”, including QAY500, QAY300, ZAT1500, ZTC650, etc. They are fixed here, including 150 tons of all-terrain cranes of type ZAT1500. , is a product developed specifically for the Hong Kong market, and ZTC650, is a 65-ton truck crane, this model fully meets the conditions for licensing in Hong Kong, and access to QPME quality machinery label.

Since entering the Hong Kong market more than 10 years ago, Zoomlion has adopted localized design and constantly customized innovative products according to customer needs. By 2017, Zoomlion has implemented cranes in the Hong Kong market. And the market share of concrete products is number one for many years. Customer-first, innovation-driven, and advancing with the times - this may be Zoomlion's "password" to maintain its leading position in the mainland and Hong Kong and Macao markets.

The relevant person in charge of the Hong Kong-Zhuhai-Macao Bridge stated: “The bridge is expected to be fully operational by the end of this year. By then, the land transit time from Hong Kong to Zhuhai will be changed from 3 hours to half an hour. The economic integration of the three places will continue to deepen, forming a super-urban cluster that attracts worldwide attention. "(This article comes from Zoomlion.)
