Stationary boom placer is a specialized device that is fixed in a specific position and delivers concrete through the expansion and rotation of a multi-section boom. The “stationary” in its name emphasizes its “immovable” nature and is commonly used for concrete placement that require long-term, efficient coverage of fixed areas.

Features Of Stationary Boom Placer
- Strong stability
Fixed installation to avoid vibration offset caused by movement, high pouring accuracy.
- Large coverage
The boom rotation and expansion can cover the radius of 15-30 meters.
- Efficient Continuous Operation
Efficient continuous operation is suitable for long time and large quantities of concrete pouring ( such as prefabricated component production line).
- Low maintenance cost
Simple structure, lower failure rate than truck-mounted or intelligent placing machine ensure low maintenance cost of stationary boom placer.
Shortcoming Of Stationary Boom Pump
- Lack of Mobility. Stationary boom placer can not be quickly transferred after installation, only suitable for fixed sites.
- The initial installation is complicated. The foundation needs to be embedded or the supporting structure needs to be reinforced.
If you need to take into account mobility, choose a truck-mounted distributor or a small mobile concrete boom placer.
If the pursuit of ultra-high coverage, a tower placing boom is recommended.

Working Principle Of Stationary Boom Placer
- Concrete Transportation
The concrete is pumped by an external pump machine or mixing plant through a pipeline to the hopper of the base of the placer.
The delivery pipe laid through the boom reaches the end hose.
- Boom Motion Control
The operator adjusts the telescopic, pitch and horizontal rotation of the boom via remote control or console.
The hydraulic cylinder drives the arm to unfold and cover different pouring points.
- Pouring Operation System
The end hose is manually or semi-automatically controlled to evenly distribute to the template or working surface.
Structure And Composition Of Stationary Boom Placer
Base And Support Structure
Fixed to the ground or concrete foundation by bolts or embedded parts to ensure stability. Some models are equipped with counterweight blocks or expansion brackets for resistance to overturning.
Rotary Support System
Achieve 360 degrees horizontal rotation of the boom to cover the broad circular working area.
Hydraulic motor or electric gear drive.
Multi-section Boom
Usually consists of 3-5 folded or telescopic arms with a length range of 15-30 meters.
The telescopic angle of each arm is controlled by hydraulic cylinder or wire rope.
Pipeline, Power and Control System
Lay concrete delivery pipes or hoses along the inside or outside of the boom. Hydraulic pumps provide power, remote control operation.
Motor drive, suitable for places with stable power supply.
Typical Application Scenarios Of Stationary Boom Placer
- Prefabricated Component Factory
Used in the production line of precast concrete wall, panels, stairs, etc., precision pouring mold and so on.
- Large-scale Industrial Facilities
Round or fan-shaped structures that need to be continuously poured, such as power plant cooling towers, storage tank foundations, etc.
- Water Conservancy Project
Fixed installation near the dam and gate, with the pump truck or trailer to complete the mass concrete distribution.
- Commercial Building Basements
Fixed installation in a deep foundation pit, covering the entire floor pouring area.
Market Positioning And Selection Suggestions
Stationary boom pump is suitable for prefabricated parts production, large-scale infrastructure and other fixed sites, high-intensity continuous operation projects.
