A few days ago, the construction of the world's tallest prefabricated residential building, Avenue South Residence in Singapore, is in full swing. In this project, several customized tower cranes of Zoomlion participated in the construction efficiently, which provided key equipment guarantee for the innovative prefabricated (PPVC) construction technology of the project, demonstrating the company's strong technological innovation capabilities.

Singapore is the industry leader in building houses with prefabricated components. It is understood that the van-type prefabricated assembly system (PPVC) (hereinafter referred to as PPVC) is to process the entire room in a prefabricated factory, complete the structure and decoration (including the ground, wall, ceiling, etc.), and form an independent module. Construction technology for hoisting on site. This is a new technology for epoch-making changes in the construction industry. The construction is more refined and "makes a house like a car." The Nanfeng Yayuan project is a landmark building using innovative prefabricated (PPVC) construction technology. The project is designed with 56 floors and is more than 200 meters high. After completion, it will become the world's highest PPVC residential building.

With the innovation of construction methods, the performance requirements of the construction equipment in the Singapore market have also changed. Yao Jianjun, a service engineer in the Asian zone of Zoomlion Construction Hoisting Machinery Company, said: “Singapore has introduced the PPVC construction method since 2017. The weight of all prefabs exceeds 30 tons, and the weight of some prefabs even reaches more than 40. Tons, leading to huge changes in the demand for tower cranes in the entire market, and new requirements for the lifting performance and safety of tower cranes, and a large number of flat-top tower cranes with a lifting torque of 1,000 ton meters and above are gradually used."

In-depth cooperation to meet demand

In order to meet the lifting requirements of PPVC, Zoomlion has in-depth cooperation with Singapore's long-term partner Changyun Group to jointly analyze market prospects and collect relevant technical parameters, and jointly develop more targeted tower cranes to meet local market needs.

Immediately, the 4.0 series T1200-64W tower crane developed by Zoomlion for overseas markets was launched, and it passed the German Rheinland certification and Singapore export certification at the end of 2018 and early 2019. The T1200-64W tower crane has a maximum lifting capacity of 64 tons and a maximum lifting torque of 13,924 kN·m. It has excellent lifting performance; the lifting and luffing speed is fast, the operation is efficient and stable, and the positioning is accurate; the product adopts 3 The meter integral standard section not only meets Singapore's inland transportation requirements, but also greatly improves on-site installation efficiency. In addition, this type of tower crane is also equipped with safety protection intelligent technology to ensure safe operation.

Thanks to its excellent hoisting performance, the T1200-64W tower crane was quickly welcomed by the market. "Strong lifting performance" and "precise hoisting" etc. received rave reviews. Since this model entered the Singapore market for the first time in early 2019, dozens of tower cranes have participated in the hoisting operations of multiple super high-rise PPVC buildings including Nanfeng Yayuan.

The relevant person in charge of the Asian Zone of Zoomlion Construction Hoisting Machinery Company said: “With the increasing maturity of Singapore’s PPVC technology, most of the future HDB projects and other related projects of the Housing and Development Bureau will vigorously promote PPVC. The T1200-64W large flat-top tower crane has significant advantages in terms of performance and quality and will usher in a broad market prospect." See Daowang Machinery Column Editor/Ge Siyu
