Summary:
In modern tunnel construction projects, initial support is a critical component for ensuring construction safety and structural stability. As a key piece of equipment in this stage, the wet-spraying robotic arm—with its advantages of high efficiency, environmental friendliness, and precision—has become a commonly used tool in various tunnel engineering projects. The ZXP4517 wet-spraying robotic arm from Zhengxun Heavy Industry, backed by its independently developed patented boom structure, large-diameter high-strength conveying pipelines, and highly efficient power chassis system, not only significantly boosts tunnel construction efficiency but also better meets the stringent requirements of high-quality support under complex geological conditions, making it an excellent choice for tunnel construction.
The ZXP4517 wet spray robotic arm from Zhengxun Heavy Industry is specially designed for tunnel construction applications. Its core advantages—wide coverage and high precision—stem from the innovative design of its highly flexible boom system. The patented boom structure, independently developed by Zhengxun Heavy Industry, supports 360° horizontal rotation and large-angle pitch-and-sway movements, effectively alleviating the issue of uneven force distribution commonly found in traditional equipment. This not only enhances the stability of the boom’s operation but also helps extend the service life of the equipment. Thanks to this design, concrete spraying can cover all critical areas of the tunnel—including the arch, sidewalls, and curves—effectively reducing instances of missed or under-sprayed spots.
The delivery pipeline of the ZXP4517 wet spraying robotic arm utilizes high-strength steel pipes with a diameter of no less than 125 mm. Compared to conventional pipelines, the larger inner diameter significantly reduces concrete pumping resistance, enabling smoother material flow, more uniform spraying, and a lower likelihood of blockages and other malfunctions. This, in turn, reduces downtime losses caused by equipment failures, ensuring continuous and stable concrete spraying and rapid formation of a dense, high-strength support layer. Moreover, the wet spraying process effectively minimizes construction dust, improves the working environment, and better aligns with the development requirements of green construction.
The ZXP4517 wet spray manipulator is equipped with hydrostatic four-wheel drive and a hydraulically assisted steering system, paired with off-road tires and a composite braking system. Even under challenging conditions—such as steep slopes and rough road surfaces inside tunnels—it can achieve flexible steering and smooth operation. Its stable power output and exceptional terrain adaptability enable the equipment to maintain optimal performance over extended periods of intensive use, providing strong assurance for construction progress.
From its core specifications to its real-world performance, every design element of the Zhengxun Heavy Industry ZXP4517 wet spray robotic arm is closely aligned with the core requirements of tunnel construction. This not only highlights the company’s profound professional expertise in the field of construction machinery but also, thanks to its stable and reliable performance, helps propel tunnel construction steadily toward mechanization, intelligentization, and green practices.
