Introduction: Automatic waterproof board laying and hanging trolley, including gantry frame, arch track, and cloth hanging mechanical device. The operating platform is composed of hydraulic oil cylinder expansion structure, hydraulic support rod, and back plate, used for extending and retracting the steel bar binding platform on both sides, allowing the two sides of the platform to extend as much as possible to the excavation surface, facilitating workers to weld waterproof boards and bind steel bars, effectively improving operator safety and reducing labor intensity Automatic waterproof board reinforcement trolley Advantages: Reduce construction personnel, reduce investment in construction equipment, and save costs. The construction period of each 12 meter long board is 8 hours, and only 3-4 people are needed to complete the laying and hanging of waterproof board steel bars, greatly improving efficiency, reducing labor intensity of workers, reducing safety risks, and achieving intelligent and mechanized construction, laying a solid foundation for rapid and efficient construction.
