What many may not know is that China's largest-diameter shield machine ever exported has a twin, a "sister machine" built with the same cutting-edge technology.

很多人或许不知道，中国出口海外最大直径盾构机是“同胞姐妹”。

The "elder sister", PATYEGARANG, is currently en route to Sydney, Australia. Meanwhile, her "younger sister", BARANGAROO, has made a striking debut in Zhengzhou.

“姐姐”叫“帕蒂加朗号”，正在运往澳大利亚悉尼；“妹妹”叫“巴兰加鲁号”，在郑州闪亮登场。

On July 30, as the cutterhead commenced gradual rotation, the super-large-diameter shield machine BARANGAROO, developed by China Railway Engineering Equipment Group Co.,Ltd.(CREG), successfully rolled off the production line at Zhengzhou's National TBM Industrialization Center. This equipment and its sister machine PATYEGARANG launched in April, will jointly undertake the Western Harbour Tunnel project in Sydney, Australia.

7月30日，伴随着刀盘缓缓转动，由中铁工程装备集团有限公司（以下简称“中铁装备”）研制的超大直径盾构机“巴兰加鲁号”在郑州国家TBM产业化中心顺利下线。这台设备与今年4月下线的“帕蒂加朗号”是一对“姊妹”盾构机，将共同服务于澳大利亚悉尼西部港湾项目建设。

Sydney's Western Harbour Tunnel will feature a twin-tube, bidirectional roadway beneath the harbour—only the second such crossing ever built. Designed with an S-shaped alignment, the tunnel reaches a maximum depth of 52 meters below sea level and includes a tight turning radius of just 960 meters. It passes through complex geological conditions, including sandstone, silt, and mixed strata. The surrounding rock presents significant challenges, with uniaxial compressive strength reaching up to 30 MPa, and up to 80 MPa in certain sections.

澳大利亚悉尼西部港湾项目跨海隧道设计为双洞双向公路隧道，建成后将成为悉尼海港下的第二条公路隧道。隧道整体呈“S”型蜿蜒前行，最大埋深海平面下52米，最小转弯半径为960米。穿越地层类型复杂多样，涵盖砂岩、粉砂、粉砂与粉质黏土层，岩层单轴抗压强度可达30兆帕，局部最高甚至可达80兆帕，施工难度极大。

Henan-made tunnel boring machines (TBMs) are breaking new ground—both at home and abroad. In recent years, as China Railway Engineering Equipment Group (CREG) has expanded its global footprint, it has closely aligned product development with international demand, advancing toward high-end, intelligent, and eco-friendly designs. Its global presence continues to grow, with a wide range of TBMs exported to more than 30 countries and regions. CREG has maintained the No.1 position worldwide in both production and sales for eight consecutive years.

从装备中国到装备世界，“河南造”盾构机不断掘进新里程。近年来，中铁装备在“走出去”的过程中，积极融入全球化浪潮，精准匹配全球客户需求，对产品进行高端化、智能化、绿色化的技术升级，国际“朋友圈”不断扩大，各类型隧道掘进机产品已出口全球30多个国家和地区，产销量连续8年世界第一。（中文来源/河南日报 记者/王延辉 编译/赵汉青 实习生 袁博文 审校/陈行洁）
