Platform lifter

Arch installation; quality inspection, grouting, charging, anchor bolt installation and auxiliary roughening

1. Safety: As equipped with three mechanical arms and three working platforms, the workers can be kept far away from the construction area of the tunnel. Compared with the conventional construction method with the arch erection, the safety performance can be improved by 80%.

2. High-efficiency: It is capable of quickly and accurately positioning the arch frame with high efficiency, which improves the efficiency by 60% compared with the conventional construction method. As no external power supply is required, it can be operated conveniently. It only takes 20-30 minutes to install one arch frame, so as to speed up the process cycle.

3. Multi-function: As designed with three arm structures, it is applicable to various arch installation methods, which is suitable for erection operations in full-section, small steps and two steps. It is suitable for the steel arch installation, anchor bolt installation, anchor mesh installation, auxiliary roughening, quality check, grouting, tunnel equipment installation, etc.

4. Labor-saving: Only 4 people are needed for one equipment to complete the steel frame installation and reinforcement mesh laying, which can save 2-3 people.

5. Money-saving: The vehicle is equipped with the flexible chassis, which can cover multiple construction areas to reduce equipment investment.

6. Local/remote control: The local or remote control can be flexibly selected according to the difference of working conditions, which can bring about high adaptability.
