28m concrete 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.Two modes of operation: wireless remote control and cable remote control can be selected according to the need. And it can be changed quickly to another system when a system fails to continue the construction.
3.Inner-climbing frames: floor frame or wall (lift or shaft) frame, which are suitable for different jobsites. The machine climbs with its climbing device, which is easy and convenient.
4.Total weight is 2-3 tons lighter than other same level products, which is beneficial to floor bearing.
5.The hydraulic pump station and electric control cabinet are integrated on the base, which is convenient to install and reduces the failure rate.
6.The parts needed to be connected on-site adopt the quick coupling, which is not only convenient to install, but also avoids the oil leakage.
