QZHP-3016B and QKSP-20A auto mobile shotcrete truck, have a concrete discharge capacity of up to 30 cubic meters per hour and a conveying capacity of up to 22 cubic meters per hour, respectively. Based on standard spraying thickness, a single unit can complete nearly 300 square meters of work surface per hour, increasing work efficiency by more than 30% compared to traditional equipment and several times that of manual spraying.

On the front lines of railway tunnel, highway slope, and water conservancy culvert construction, concrete spraying and shotcrete is always of paramount importance—ensuring project quality, meeting deadlines, ensuring safety, and balancing environmental protection and cost.

The QKSP-20A medium-sized robotic shotcrete machine wet concrete spraying trolley is more suitable for small to medium-sized work conditions, balancing efficiency and flexibility. Its theoretical spraying capacity can reach 22m³/h, meeting the spraying needs of small to medium cross-section projects. A single unit can complete nearly 300㎡ of work surface construction per hour, several times more efficient than traditional manual spraying.

Saintyol DAWIN wet concrete spraying trolleys are equipped with high-efficiency spraying systems, with different models each having their own focus: the QZHP-3016B has a concrete discharge capacity of up to 30 cubic meters per hour, while the QKSP-20A has a conveying capacity of 22 cubic meters per hour. Based on standard spraying thickness, a single unit can complete nearly 300 square meters of work surface per hour

Saintyol DAWIN Machinery wet concrete shotcrete robot cover large, medium, and small cross-section working conditions, featuring dual power, large displacement, wide coverage, and low rebound, adapting to different engineering needs. the QZHP-3016B large wet spraying trolley is the preferred model for large cross-sections, with a theoretical spraying volume of up to 30m³/h, It has a vertical spraying height of 16m and a horizontal spraying width of 27m, and its wide coverage reduces blind spots

In the construction engineering field, concrete pumping has always been a core element determining construction schedule and quality. High-rise building pouring faces challenges such as insufficient or unstable concrete delivery, unsuitable equipment leading to inefficiencies in special working conditions, and large-scale projects with low tolerance for error and stringent requirements

In the construction of high-rise buildings, any interruption in concrete pouring not only affects the overall structural integrity but may also disrupt the rhythm of subsequent processes such as rebar installation, formwork, and curing. Ensuring uninterrupted concrete placement becomes a crucial issue in project management. Konel Heavy Industry's hydraulic placing boom addresses this need by providing a continuous, autonomous, and low-dependency solution.

Pre-installation Inspection, First, before installing the concrete placing boom, carefully inspect each component and pipe clamp of the assembled boom.

Saintyol DAWIN wet concrete shotcrete truck is widely favored in the market due to its high efficiency. However, under the pressure of high-intensity construction operations, wet spraying trolleys are prone to wear and tear over time. Therefore, routine maintenance is crucial, especially the maintenance of core components and critical parts, which directly affects the equipment's operating efficiency and service life.

In concrete shotcrete support construction for tunnels and slopes, the flexibility and coverage of equipment directly determine operational efficiency and construction quality. Saintyol DAWIN machinery wet concrete shotcrete trolley, with its innovative boom system and precise track control, provides a high-performance solution for modern shotcrete construction.

In a high-altitude tunnel at 4,200 meters above sea level, amidst sub-zero temperatures and winds, Saintyol DAWIN shotcrete machine is operating smoothly. What used to require three people can now be done by one, with the quality pass rate soaring from 85% to 98%. This isn't science fiction; it's the daily reality of Saintyol DAWIN intelligent equipment.

Concrete placing boom Hydraulic system "physical examination" 1. Oil circuit hidden dangers: Check whether there are leaks, loose joints or surface damage in the hydraulic pipeline before starting, especially pay attention to bends and welding points. If the oil is turbid or contains bubbles,

The mechanical properties of concrete pumps, such as sand and gravel particle size, cement grade and mix ratio, are generally explained in the factory manual. Qingke Heavy Industry reminds you to follow the factory manual to meet the mechanical properties of concrete pumps during operation. The safety requirements for using concrete pumps are as follows:

High temperatures in summer can reduce the concrete placing boom viscosity of hydraulic oil, leading to unstable system pressure and even leakage. Before construction, check the oil level and quality of the hydraulic oil to ensure that the oil level is within the normal scale range. If the hydraulic oil is found to be darker, turbid or has impurities, replace it with anti-wear hydraulic oil that meets the summer use standards in time.
