PB35A-4R-E Self-Climbing Placing Boom

PB35A-4R-E
Placing boom PB35A-4R-E is equipped with the self-climbing device, climbing by hydraulic cylinder according to building height. The self-climbing device instead of manual type gradually and become more and more popular in the market. 

The operation method of this type placing boom become more simplified which can be operated only by 1 or 2 workers by controlling arms with radio remote control and cable remote control. It effects accurately concrete pouring uninterrupted which improving the efficiency and convenience. It also reduces labor intensity and saves on user cost. Compared with other type of column and climbing concrete placing boom, PB35A-4R-E can cover the bigger working range and meet different demands of jobsite.

Features of Self-Climbing Placing Boom

  1. The balance valves is supplied by NEM Company from Italy.

  2. The solenoid directional valves are supplied by Rexroth Company from Germany, or the ATOS from Italy.

  3. The main electronic components are purchased from the world-famous brand such as Scheider  and  Omron which make stable and reliable quality.

  4. Two operation method which can meet different demand from clients : radio remote control and cable remote control.

  5. Electric-hydraulic proportional control which makes placing boom more stable and the speed is more adjustable.

  6. Intergrated design for pump station and electric control cabinet which installed in the lower support, which easy for installatioin and also reduce failure rate

  7. The column has an octagonal cross section, lighter weight and greater bearing capacity.

  8. Each column has universal interchangeability. When adding or reducing columns, it is more convenient to increase or decrease the conveying pipe and ladder.

  9. The boom is a four-section arm made of high-strength steel plate with light weight and high strength. The corner of the arm reaches 210° and the cover the wider working range.

  10. The weight of the lifting unit is greatly reduced, which can better meet the lifting requirements of the construction site.

  11. The special design of hydraulic oil container which simplified process of

  12. Replace and repair. It also save the cost for customers.
