Summary:
Common pain points in tunnel construction include high costs for transporting external air compressors, lengthy duct‑laying schedules, and the lack of on‑site air‑supply infrastructure at remote job sites—resulting in unnecessary delays. The ZXP4517K wet‑spraying rig from Zhengxun Heavy Industry directly addresses these industry challenges: its innovative design integrates a high‑performance, dedicated air‑compressor system, delivering an impressive 45 m³/h spray rate, paired with a patented boom. With no need for an external air source, the machine is ready to operate as soon as it arrives on site, setting it apart from standard models on the market. It is ideally suited for all types of support‑work applications, including underground tunnels, slope stabilization, and hydraulic engineering projects.
Exclusive differentiation: integrated, customized design for air compressors.
Construction is not constrained by the site.
Some wet-spraying rigs on the market require a separate air compressor, necessitating the transport of two pieces of equipment when relocating and on-site connection of air hoses, which is highly inconvenient for operations in narrow tunnels, remote mountainous areas, or open‑air slopes. The ZXP4517K supports power, air pressure, Inverter air compressor Customizable on demand, with fully integrated, all-in-one design and a built-in stable high-pressure air‑supply system, it is the ultimate solution for wet spraying that enables truly standalone operation as a single unit.
The core function of an air compressor
01
Stable high-pressure air supply, reducing rebound.
It continuously delivers uniform wind pressure, enabling concrete to adhere rapidly to the surrounding rock. Rebound rate Keep it below 10%, significantly reducing raw material costs, while ensuring the sprayed layer meets the required density and support standards.
02
No external equipment required—start construction as soon as you arrive on site.
Eliminates the need for air compressor rental, transportation, and ductwork installation; single-operator remote control reduces upfront preparation time by 30%.
03
Continuous air supply in complex environments
The variable-frequency air compressor delivers quiet, energy‑efficient performance and can stably provide airflow even at high altitudes and on remote construction sites without an external power supply, free from the constraints of auxiliary equipment.
Compatible with all construction scenarios
Long-distance jetting results in significant duct losses.
With an integrated air compressor providing localized air supply, long‑distance air‑line pressure losses are eliminated, ensuring stable and sufficient jetting pressure, reducing shotcrete rebound, and significantly enhancing the quality and continuity of long‑distance support operations.
No fixed high-pressure air source
No air compressor required, no ductwork needed; stable air pressure, compact footprint, quick relocation, reduced consumables and labor, and continuous, efficient construction.
Hydropower and Water Conservancy Engineering
Water diversion tunnels, underground powerhouses, and the inner linings of embankments can all be continuously sprayed for reinforcement, even in remote reservoir areas where no auxiliary equipment is available.
Inconvenient on-site power supply; no industrial electricity.
No external cabling is required; the unit operates on its own power supply, eliminating the need for additional power infrastructure and freeing it from grid constraints, allowing shotcrete support to be deployed at any time.
Emergency Rescue Project
For emergency projects such as landslides and subgrade repairs, a single machine can be rapidly deployed to swiftly complete concrete support and reinforcement.
A robust, all‑round advantage puts it ahead of its peers across multiple dimensions.
45 m³/h high-capacity pumping, delivering maximum efficiency.
Most mainstream models in the industry deliver 30–40 m³/h, whereas the ZXP4517K boasts a theoretical pumping rate of 45 m³ per hour. Its large‑diameter, wear‑resistant conveying lines, combined with an anti‑clogging pumping design, ensure reliable operation over extended periods without pipe blockages, significantly shortening the construction schedule for large‑area support work. Equipped with two high‑capacity rapid‑setting agent tanks and a central CPU‑controlled intelligent mixing system, it achieves uniform and stable setting of sprayed concrete layers.
Patented multi-degree-of-freedom boom, with full coverage and no dead angles.
Self-developed, stackable telescopic rotating boom; 360° omnidirectional adjustment; maximum working height of 18 meters; enables precise spraying at the arch crown, corners, and base face, with no missed spots or blind zones. High-strength. Slewing bearing , even when fully loaded, it remains stable during extension, significantly reducing equipment vibration and wear, and extending service life by 70%.
Four-wheel-drive off-road chassis, effortlessly handles challenging terrain.
Hydrostatic four-wheel drive plus hydraulic power steering ensures effortless travel on deep gravel, tunnel ramps, and muddy construction sites; with a tight turning radius, it offers agile U-turns in narrow passageways. Paired with reinforced heavy-duty tires, it delivers robust load-carrying capacity and stable, safe performance during heavy‑load transport.
100-meter wireless remote control, safe and intelligent operation
Dual wired/wireless remote control with a maximum operating range of 100 meters, allowing operators to stay clear of the hazardous face and avoid injuries from falling rocks and dust. The entire machine is equipped with a self‑diagnostic system, providing real-time visualization of pressure, air pressure, and pumping parameters, and can be easily mastered after brief training.
Choose the ZXP4517K—your one-stop solution for construction challenges.
Compared with a split‑type air compressor paired with a conventional wet‑spraying rig, the Zhengxun ZXP4517K integrated custom solution offers distinct advantages: it reduces equipment procurement and rental costs by eliminating the need for an additional unit, while also cutting expenses associated with air hoses and generator sets. Versatile across diverse settings—such as open‑pit sites, underground mines, and tunnels—a single machine can handle multiple support‑construction tasks, effectively doubling equipment utilization.
From urban subways to remote mountain‑top water‑conservation projects, and from mine tunnels to slope‑stabilization works, Zhengxun Heavy Industry’s ZXP4517K has earned its reputation as the preferred equipment for efficient engineering support, thanks to its customizable built‑in air compressor, high production capacity, and exceptional flexibility. With this robust machinery, it helps infrastructure projects achieve higher quality and greater efficiency.
