Zoomlion's basic construction machinery has achieved new success in the European market. Its newly upgraded U-series rotary drilling rig, with industry-leading intelligent technology and excellent performance, has successfully completed mass delivery of the entire series of products. Among them, flagship models such as ZR255U, ZR300U, and ZR420U have won multiple large orders with outstanding performance, triggering strong reactions in the field of infrastructure construction in Europe.
These high-end devices, hailed as "engineering tools," are reshaping the European market's perception of Chinese manufacturing. "Zoomlion's intelligent rotary drilling rig has completely changed our construction method, "local customers reported." Unprecedented ease of operation, dynamic power performance, and precise construction accuracy have enabled us to achieve a qualitative leap in engineering efficiency."
Multiple U-series rotary drilling rigs debut in the European market
The U-series rotary drilling rig is a product specially designed by Zoomlion for the European market in foundation construction.
All products in the series have passed CE certification and comply with Euro V emission standards. This series is standard-equipped with a winch pressurization system and adopts a multi-purpose design, which can flexibly switch between Kelly drilling rig and CFA mode, fully meeting the construction needs of various complex working conditions.
Shanghai and Munich Bauma double exhibitions released
At the Bauma exhibition in Shanghai in 2024 and the Bauma exhibition in Munich, Germany in 2025, Zoomlion launched its flagship U-series drilling rig, the ZR400U rotary drilling rig. This model has the ability to switch between six advanced construction methods and can be flexibly applied to different construction scenarios such as Kelly drilling, low clearance drilling (LHR), full casing drilling (Casing), long spiral continuous drilling (CFA), pipe rolling machine (Oscillator), and vibratory hammer drilling. It can be regarded as a versatile product in the field of multifunctional rotary drilling rigs.
6 major construction methods of ZR400U rotary drilling rig
The U-series rotary drilling rigs are equipped with intelligent construction as the standard configuration, innovatively integrating five intelligent functions: one key hole scanning, one key soil throwing, one key pipe rolling machine oil supply, one key rock entry, and centralized lubrication. By simplifying the operation process, the construction efficiency is improved by more than 30%. In terms of construction performance, this series of equipment has four core functions: power head floating, integrated connecting plate, full stroke winch pressurization, and full stroke winch floating, which can easily cope with various complex geological conditions. Among them, the full stroke winch pressurization system provides strong pressurization force to ensure drilling accuracy; The full range hoisting and floating function significantly reduces construction vibration and greatly improves operational stability.
In landmark housing projects such as large residential areas, the ZR420U model efficiently completes deep foundation pile construction with its excellent performance of 430kN · m super torque and 3-meter super pile diameter, becoming a reliable guarantee for the foundation engineering of super high-rise buildings. The customer highly praised the U series: "From equipment delivery to after-sales support, the professional competence demonstrated by the Zoomlion team has made us worry free throughout the entire process." The customer manager particularly appreciated the efficient response ability of the localized service team.
Zoomlion adheres to the dual wheel drive of technological innovation and localized services, and accelerates the expansion of the "the Belt and Road" market. The successful application of the U-series models not only demonstrates China's global strength in high-end equipment manufacturing, but also provides strong support for the development of world infrastructure. Looking ahead to the future, Zoomlion will continue to promote high-quality development of global engineering construction with intelligent and green innovative products!
