40B Robotic Wet-Spraying Trolley

1. The equipment features a simple structure and strong adaptability. 2. It delivers high pumping pressure and enables long-distance conveying. 3. High efficiency: large delivery capacity and superior overall productivity. 4. Superior performance: the sprayed concrete exhibits excellent density, uniformity, and high strength. 5. High reliability: key components are sourced from well-known domestic brands, ensuring dependable operation. 6. Accelerator addition and control technology: a renowned pneumatic metering pump is employed for precise dosing; atomized spray and nozzle flow ensure thorough and even mixing of the accelerator with the concrete. 7. Dust concentrations near the machine and outside the nozzle are significantly reduced, thereby eliminating health risks to workers. 8. Low rebound rate: in dry spraying, concrete rebound can reach 15%–50%; by contrast, wet spraying reduces the rebound rate to below 10%, resulting in substantial cost savings. 9. Hydraulic oil is cooled using an air‑cooling system, which is both simple and environmentally friendly.

Product Introduction

1. The equipment has a simple structure and strong adaptability.

2. High pumping pressure and long delivery distance.

3. High efficiency: large conveying capacity and high overall productivity.

4. High Performance: Shotcrete exhibits excellent performance, characterized by high density, uniformity, and superior strength.

5. High Reliability: Key components are sourced from well-known domestic brands to ensure the equipment’s high reliability.

6. Accelerator Addition and Control Technology: A well-known pneumatic metering pump is employed, ensuring precise dosing. The atomized spray stream mixes with the nozzle’s material flow, achieving uniform dispersion of the accelerator throughout the concrete.

7. It reduces dust concentrations both at the machine side and outside the nozzle, thereby eliminating health hazards to workers.

8. Low rebound rate. During dry spraying, the concrete rebound rate can reach 15%–50%; by contrast, wet spraying can reduce the rebound rate to below 10%, resulting in significant cost savings.

9. Hydraulic oil is cooled using air cooling, which is simple and environmentally friendly.
