Summary:
In tunneling and underground construction, the quality and efficiency of initial support directly impact project safety and schedule. Zhengxun Heavy Industry’s ZXP4017/4517/5517 series wet‑mix concrete spraying rigs, leveraging multiple proprietary core technologies, deliver the most reliable and cost‑effective solution for concrete spraying operations in complex working conditions.
I. Boom System: Flexible and Precise, with Comprehensive Coverage and No Dead Zones
The ZXP series is equipped with a highly flexible boom system that supports 360° horizontal rotation and large‑angle pitch oscillation, ensuring complete, dead‑zone‑free coverage during spraying operations. Zhengxun Heavy Industry’s proprietary, self‑developed boom‑balancing structure, refined through advanced structural analysis, effectively eliminates the risk of uneven loading, resulting in uniform stress distribution and smooth operation. This fundamentally addresses the sway issues caused by off‑center loads in conventional equipment, extends the service life of structural components, and reduces maintenance costs. 
II. Slewing Bearings and Transmission System: Reliable and Durable, Easy to Maintain
Key components of the equipment feature a large‑diameter internal‑gear slewing bearing, offering high meshing strength, excellent stability, and extended service life. The top‑mounted layout of the slewing reducer provides ample working space for routine maintenance and repairs. Large‑diameter delivery pipelines—made of high‑strength steel with a diameter of ≥125 mm—effectively reduce pumping resistance, enhance concrete flowability, and ensure superior spraying quality.
III. Power and Air Compressor Systems: Flexible Compatibility, Energy Efficiency and High Performance
The ZXP series from Zhengxun Heavy Industry offers three compressor power options—75 kW, 90 kW, and 110 kW—providing flexible adaptation to diverse operating conditions. Its dual‑fuel electric–diesel power system prioritizes electric operation for routine construction, delivering energy efficiency and environmental protection, while diesel serves as an emergency backup with automatic switching to ensure uninterrupted operations. Customized energy‑efficient motors are available in three power ratings—65 kW, 75 kW, and 90 kW—ensuring robust performance while effectively reducing operating costs.
IV. Accelerator Supply and Spraying Efficiency: Large-Capacity Assurance, High-Intensity Continuous Operation
The dual 1,000‑liter high‑capacity accelerator tank design significantly enhances the storage and delivery capacity of the accelerating agent. This configuration is particularly well suited for large‑scale, high‑intensity construction projects, effectively minimizing disruptions caused by frequent re‑loading of the accelerator and ensuring continuous operations. The accelerator flow rate is automatically adjusted based on the pumped concrete volume, reducing material waste. Zhengxun Heavy Industry’s ZXP series delivers a theoretical spraying rate of 40–45 cubic meters per hour, with a concrete rebound rate kept below 10%, markedly improving productivity and lowering material consumption compared to conventional methods.
Zhengxun Heavy Industry’s ZXP series wet‑spraying rigs leverage a suite of core technologies—including a patented boom, large‑diameter slewing bearings, optional high‑power air compressors, dual 1,000‑liter rapid‑setting agent tanks, and dual diesel‑electric power—providing efficient, reliable, and cost‑effective shotcrete support solutions for tunneling, mining, slope stabilization, and other projects. From equipment selection to the entire construction process, Zhengxun Heavy Industry is committed to ensuring that every cubic meter of concrete adheres precisely to the rock face, making each spray application a dependable enabler of project progress.
