21m Formwork climbing placing boom Product Features 1.Three arms design, “R” folding. The machine is fully driven by hydraulic, both folding and unfolding are flexible, and can slew 360°with wide working range. Arms adopt high strength
1.Three arms design, “R” folding. The machine is fully driven by hydraulic, both folding and unfolding are flexible, and can slew 360°with wide working range. Arms adopt high strength steel plate which is stronger and lighter.
2.The machine adopts modular design which can be linked quickly by pin shafts, easy to install, disassemble, and transport.
3.Two modes of operation: wireless remote control and cable remote control, easy to operate.
4.The machine climbs by climbing frame to reduce the workload of climbing, and increase the efficiency.
5.Adopting 45Mn2 delivery pipe with longer life-time, reduces the frequency of exchanging, and rises work efficiency.
