Concrete placing boom can be divided into stationary concrete placing boom, mobile concrete placing boom, self-climbing concrete placing boom, which is one of construction equipment . stationary concrete boom is also called concrete spider placing boom. This article introduces three placing booms definition and technical features.

Concrete placing boom definition
Stationary concrete placing boom, which is dedicated for railway-bridge, nuclear power and other engineering constructions, is designed by our company on the basis of specialized production of concrete spreaders for many years. Now it is a quite mature product through constant optimization and upgrading.
Mobile hydraulic concrete placing boom with "Z" shaped three sections folding arm, 360 ° rotation, which can achieve full-casting within the boom length to three-dimensional space, can easily achieve the various concrete pouring to wall, pipes, columns, piles etc. It is of high reliability, efficiency and convenience, which could be working together with concrete pump for concrete pumping and placing in construction projects.
Elevator type self-climbing concrete placing boom is used for concrete placing in high building projects. Equipped with self-climbing frames which are driven by hydraulic cylinders, could be self-climbing along elevator hoist way as building rising, which can save time and labor with high efficient.

Stationary Concrete placing boom technical features
1. Horizontal reach: 13-23m (not including the end hose), Mode of drive: fully hydraulic.
2. When a placing boom is in use, it is anchored to the floor with initially prepared holes. If it is required to rise up, a tower crane is needed to lift the placing boom up to the next higher floor for being anchored. And one rising of the placing boom can meet the requirements of concrete placing for two floors.
3. If the floor is large in size, it is advisable to have several tower bodies mounted on the floor so that only one boom assembly is needed to be lifted to mate to the tower bodies, thereby saving boom-assemblies and cost.
4. Compact design,easy operation, reliable safety, economic and practical, suitable for the construction of high buildings.
5. This type concrete placement boom can designed as well as mobile placing boom data, and used with concrete truck mixer
