Description
Introduction
Articulated Wet Concrete Sprayer is a kind of wet concrete spraying machinery and equipment specially designed for the construction of tunnels, mines and large underground projects.
Advantages
High-Efficiency Spraying
The equipment utilizes a high-pressure wet spraying system, achieving a maximum spraying rate of 20–25 m³/h, approximately 30% higher efficiency than traditional dry spraying.
Articulated Structure
The multi-degree-of-freedom articulated arm design provides a wide reach and flexible rotation, enabling coverage of narrow lanes and high-arch tunnels.
Dust Reduction and Environmental Protection
The dust concentration during wet spraying is controlled to ≤ 2 mg/m³ (in compliance with international occupational health standards), significantly lower than the 10–20 mg/m³ of dry spraying.
Durable Design
The equipment utilizes a wear-resistant alloy nozzle and high-pressure piping, and the hydraulic drive system features overload protection, minimizing failure rates and ensuring stable operation.

FAQ
Q: What is the minimum order quantity?
A: We accept orders of one unit and offer preferential pricing and fast delivery for larger orders.
Q: What is the product warranty and after-sales service?
A: The entire machine has a 12-month warranty, and extended warranty coverage is available for key components (nozzles and hydraulic systems). We provide remote technical support and on-site training to help customers quickly get up and running.
Q: What is the lead time?
A: The lead time for standard models is approximately 20–30 days. For customized models, the lead time varies depending on the specific configuration, but is generally 30–45 days.
Q: What is the difference between wet and dry shotcrete?
A: Wet shotcrete has a high moisture content, low dust, and low rebound, making it more environmentally friendly and efficient. Dry shotcrete, on the other hand, produces high dust and high rebound, making it unsuitable for modern large-scale tunnel and underground construction.
Q: Can the machine operate in narrow tunnels?
A: Yes. The articulated boom design is optimized for confined working spaces, with a minimum turning radius of only 3 meters, making it suitable for mine and small-section tunnel construction.
Q: Do consumables need to be replaced frequently?
A: The equipment utilizes wear-resistant alloy nozzles and high-pressure hoses, boasting a lifespan 1.5–2 times that of standard materials. Requiring minimal daily maintenance, this significantly reduces ongoing maintenance costs for wholesale customers.
