Concrete wet spraying trolley: a tunnel support expert with flexible boom and precise spraying.

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.

I. Flexible Boom Design for Efficient Operation with No Blind Spots: The core advantage of Qingke Heavy Industry's wet spraying trolley lies in its advanced boom system. It employs a combined boom and forearm design, with the forearm featuring a unique telescopic function. This design greatly enhances the equipment's mobility, allowing the nozzle to easily reach complex areas that traditional equipment struggles to cover. Whether it's the tunnel arch, sidewalls, or invert, it achieves rapid and precise positioning, significantly reducing manual labor and improving construction efficiency. 

II. Wide Operating Range for Diverse Construction Scenarios: With an excellent spraying height of 16 meters, it can easily meet the support needs of large tunnel sections. Its boom can achieve an elevation angle adjustment of 0-60°, while the forearm has a wide pitch angle range of +15° to -35°. This wide range of joint movement allows the nozzle to cover the entire working surface from bottom to top at the optimal angle, ensuring dense and uniform concrete spraying and effectively guaranteeing the quality of the support layer. 

III. Precision and Stability, Enhancing Construction Quality and Safety The telescopic and pitching functions of the forearm, combined with the lifting of the boom, allow the operator to remotely complete all positioning operations from the cab. This not only reduces over-reliance on operator experience but also completely liberates workers from high-risk, high-dust work surfaces, greatly improving construction safety. Simultaneously, the stable hydraulic system ensures the smoothness of the spraying process, effectively reducing rebound and saving material costs.
