KC3017/3019W Adaptable and Wet Spraying Trolley for Water Conservancy Culvert Construction by 17/19m Long Distance Shotcrete
The application of our KC3017/3019W in construction is mainly reflected in tunnel engineering, especially playing an important role in infrastructure construction such as railways and highways. As a large concrete wet spraying trolley, the wet spraying robotic arm integrates the three functions of walking, pumping, and spraying. It adopts wireless remote control operation, replacing manual spraying operation. It has high construction efficiency, fast spraying speed, low rebound rate, and high concrete density, thereby improving the construction environment, reducing construction costs, and improving construction progress.
Applications
Railway tunnel: In railway tunnel construction, wet spraying trolley can effectively accelerate the construction speed and improve the quality of concrete construction.
Highway tunnel: In the construction of highway tunnels, wet spray trucks can significantly improve construction efficiency, ensuring the safety and quality of tunnel construction.
Water conservancy culvert: In the construction of water conservancy culverts, the wet spraying trolley can adapt to complex construction environments and ensure construction quality.
Mining tunnels: In the construction of mining tunnels, wet spraying trolleys can effectively control the rebound rate of spraying and improve construction efficiency.
Embankment slope: In the construction of embankment slopes, wet spraying carts can provide stable concrete spraying effects.
Building foundation pit: In the construction of building foundation pits, wet spraying carts can ensure the stability and safety of concrete structures.
Urban pipeline network engineering: In urban pipeline network engineering, wet spray trucks can adapt to complex underground construction environments.
Underground engineering: In underground engineering, wet spraying trucks can provide efficient concrete spraying solutions
Features
1. Efficient spraying performance: KC3017/19 wet spraying trolley can spray 30 cubic meters of concrete per hour, with a large operating range, a positioning distance of up to 15/17 meters, a height of up to 17/19 meters, and only 3.4 minutes per cubic meter of concrete.
2. Flexible rotation and swing: The nozzle has functions of 360 degree rotation and around 240 degree swing, with a wide coverage, low spray blind zone, low rebound rate, and high spray quality.
3. Advanced technology: Adopting advanced electro-hydraulic proportional technology and controller technology to ensure the accuracy and stability of operation.
4. Automatic adjustment function: The speed of the accelerator pump can be automatically adjusted according to the amount of concrete sprayed, which improves the flexibility and efficiency of construction
5. Stable chassis: Using self-made rigid chassis, front axle floating, four-wheel steering, four-wheel crab walking, ensuring stability and flexibility during the construction process
6. Flexible Arm Extension: Folding+Telescopic Arm Frame Design, with independent extension and retraction of the large and small arms, suitable for various construction environments
7. Multifunctionality: It integrates multiple functions such as pumping, spraying, walking, and remote control. Operators can accurately control the spraying arm from a safe distance through the remote control, greatly reducing the risk of safety accidents
