Hydraulic concrete placing boom could be working together with concrete pump for concrete pumping and placing in construction projects.

Advantages are as follows:

1)The placing boom has a R-shaped boom assembly with three foldable sections, which can swing through 360 degrees while luffing, folding, unfolding, thus allowing it to place concrete to form walls, pipes, columns, piles and other vertical structures without confined placement areas.

2)The boom assembly’s luffing, folding/unfolding and swinging are carried out hydraulically with buttons. The hydraulic and electrical system feature overload protectors, flow controls, alarms, phase sequence protectors and so on, which ensures the placing boom to have reliable performance, easy and smooth operation, and high safety.

3)Featuring compact structure and lightweight, the placing boom can be completely lifted and transferred to any suitable places for concrete placement, such as floors, platforms, simply-structured racks or even trailers. It does not need to be fixed while working. In addition, it can be lifted off the placement sites when it is not needed, which leads to no disturbance to other jobs and easy maintenance.

Selling points:

1.The hydraulic system of HG series concrete placing boom can realize 360° slewing; the balance valve and solenoid directional control valve are relatively imported from Italian Oil control and Germany Rexroth.

2.Main components if HG series concrete placing boom are imported from world famous companies such as Japan Omron and France Schneider.

3.Both wired and wireless remote control is available.

4.The slewing mechanism is normally closed type, that means slewing brake is always closed in general working conditions except that the slewing motor is connected with oil, the whole vehicle can not slew, the placing boom is fixed to avoid collision.

5.Low cost: the delivery bend pipes are accurately bend-cast, thus even the wearing of the pipes and prolong its service life.
