Equipped with a high-power engine, it can autonomously climb slopes of up to 30%. Its four-wheel steering system ensures a minimum turning radius of just 5 meters, and when paired with an electronic shift system, it perfectly adapts to all kinds of complex operating conditions.

　　We currently offer three models of wet spray trucks for your selection: QLS35A, QLS35B, and QLS35K. Below are the distinct features of these three wet spray trucks:

Comparison of different models

　　The QLS35A concrete wet spraying carriage is the first wet spraying product developed by leveraging advanced technological advantages. This model boasts stable and reliable performance, large spraying capacity, high operational efficiency, flexible control, and rapid relocation capabilities.

　　The QLS35B concrete wet spraying carriage is a new product developed based on market demands and combined with technical expertise. This product features stable and reliable performance, large spraying capacity, flexible and convenient operation, ample maintenance space, powerful engine, and precise control of setting agents. It can effectively address the challenging issues encountered in shotcrete operations.

　　The QLS35K concrete wet spraying carriage is a product developed based on advanced technological advantages. This model comes equipped with its own air compressor, making it suitable for construction sites at high altitudes or where airflow is insufficient. It offers significant advantages over similar products in terms of performance, operability, and ease of maintenance.

Structural features

　　1. Chassis

　　Welded engineering chassis with a stable structure and strong load-bearing capacity. Made with ample, robust, and durable materials, it exhibits minimal frame sway during boom operation and little deformation of the support legs when the vehicle is in use.

　　2. Robotic arm

　　① The telescopic structure undergoes 10,000 cycles of fatigue vibration, ensuring a longer service life. The telescopic arm is operated via a three-link remote control, which is simple and convenient to use. Operators can quickly become proficient, guaranteeing high-quality spraying and making it easier to ensure smoothness and evenness.

　　② The boom length is sufficient, and the chassis is sturdy and stable, allowing the boom to be fully extended. It is suitable for applications such as slope stabilization, hydropower station rehabilitation, mine reclamation, and more. The robust and durable boom can be paired with specialized tools to treat over-sprayed areas, ensuring smoothness and construction efficiency.

　　3. Covering parts

　　The integrated frame structure effectively increases the internal space for maintenance and servicing compared to competing products from similar manufacturers. When performing maintenance on components such as the engine and valve blocks that are located inside the cover assembly, there’s no need to use a loader to remove the large cover. Instead, personnel can directly carry out maintenance operations from within the cover assembly itself, significantly reducing maintenance time.

　　4. Concrete delivery pipe

　　The design is well-organized, allowing for quick assembly and disassembly, and the pipes are resistant to clogging. The inner walls of the pipes are solid and wear-resistant, ensuring a long service life. This reduces the frequency of material pipe replacements, thereby saving costs.

Performance advantages

　　1. Walking System

　　High-power engine delivers robust power and exceptional hill-climbing capability—perfect for construction sites with steep slopes, eliminating the need for loaders to pull equipment and ensuring the safety of maintenance personnel. Four-wheel steering features a small turning radius, effectively addressing the challenge of making tight turns in narrow sections or tunnel junctions. This significantly reduces the time required for site transitions—for instance, since rapid repositioning is possible, two tunnel faces at both the entrance and exit can share a single piece of equipment, thereby cutting down on equipment rental and purchase costs. Optional electronic gear shifting allows the vehicle to handle complex road conditions more easily, further enhancing safe driving performance.

　　2. Pumping System

　　The pumping capacity reaches 35 m³/h, shortening the working time per shift and making the spraying process more efficient.

　　3. Rapid-setting agent system

　　① Use a frequency-conversion motor coupled with a hose pump to deliver the rapid-setting agent, enabling stepless adjustment of the rapid-setting agent dosage from 0.5% to 10%.

　　② All components of the rapid-setting agent system are made from corrosion-resistant materials, ensuring reliability and durability.

　　③ The frequency converter precisely controls the dosage of the rapid-setting agent. The system can directly adjust the proportion of the rapid-setting agent, and when paired with an optional built-in air compressor that ensures sufficient airflow, it can effectively control rebound and save on spraying materials.

　　4. Electro-hydraulic System

　　① The electro-hydraulic systems all feature internationally renowned brands, offering sensitive response and stable operation. A dedicated 150-meter remote control ensures a stable and reliable connection. Paired with a load-sensing hydraulic system, these systems deliver even greater energy efficiency and performance.

　　② The dedicated remote control is equipped with a universal joystick handle and is compatible with multi-way valves for the boom that respond to analog signals. This allows for flexible remote operation, ensuring sensitive and rapid response from the spray nozzles. The nozzle deviation can be kept within 5 cm, enabling quick and precise targeting of under-excavated areas and guaranteeing the smoothness of the sprayed surface. Combined with the nozzle’s sweeping function, this system provides rapid and thorough surface coverage. When set to its maximum pumping rate of 35 m³/h, it not only accelerates the completion of spraying tasks but also ensures exceptional surface smoothness.

　　5. Gas circuit system

　　An air compressor ranging from 75 to 110 kilowatts can be optionally equipped. For construction sites located at high altitudes or in tunnels with insufficient airflow, you can select an air compressor of a different power rating based on the actual site conditions. This approach ensures both optimal construction performance and effective control of equipment purchase or rental costs.
