1. 3- or 4-arm design, fully driven by hydraulic system, slew flexibly with wide working range. The arms are made of high tensile steel plate, large strength and lightweight.

2. Two optional operation modes: wireless remote control and cable remote control, easy to operate. 

3. Inner-climbing frames: floor frames or wall (lift or shaft) frames, which are suitable for different jobsites.

4. Each move is controlled by electrohydraulic proportional valve, more stable and less impact.

5. The main electronic components are world-famous brand, with high quality and stable performance.
