1. Lattice tower type concrete placing boom is the perfect combination of tower body and boom assembly, which fully exhibits their respective advantages: tower body can be added mast section to lengthen the height and boom can place the concrete.

2. It can rise along with the building by climbing frame and adding mast section. And it can adhere to the wall when the building is higher than mechanical free standing height.

3. Equipped with lifting mechanism, it can lift mast section when climbing.

4. Four arms design. It is fully driven by hydraulic system and can slew flexibly, with wide working range. Arms made of high tensile steel plate features larger strength and lighter weight.

5. Two modes of operation: wireless remote control and cable remote control, easy to operate.

6. Each operation is controlled by electro-hydraulic proportion control, stable move with little impact.

7. Main electronic components are world-famous brand, with high quality and reliable performance.
