Concrete spreader

Concrete placing machine is the end equipment of pumping concrete, its main role is to send the pumped concrete through the pipeline to the formwork of the components to be poured.

I. Structure and composition

The concrete placing machine is mainly composed of the following parts:

• swivel frame: A synthetic motion consisting of a two-part slewing frame is able to cover all fabric points within the radius of the fabric.
• Fabric armFor example, the mobile fabricator adopts "Z"-shaped three-section folding arm, which is able to realize 360°turning, and has the functions of pitching and spreading and folding, in order to adapt to the pouring needs of different heights and angles.
• ducts: Connecting the placing arm to the concrete pumping equipment is usually done with a high-strength, abrasion-resistant steel or plastic pipe with a smooth internal coating to reduce frictional resistance.
• Hydraulic and electrical systems: Provides power and control for the fabricator, ensuring stable operation and accurate fabrication.

II. Principle of operation

The working principle of the concrete placing machine is to transport the concrete to the part that needs to be poured through the pipeline, so as to realize the automatic pouring. The concrete steps are as follows:

1. Fill the hopper with concrete.
2. Start the mixing mainframe to mix the concrete well (some placers may not include a mixing mainframe and receive concrete directly from the concrete pumping equipment).
3. Concrete is transported to the spray nozzles of the placing boom by means of a high-pressure hose.
4. The spray nozzle sprays concrete onto the area to be poured to complete the pouring operation.

III. Classification and models

Depending on the different pouring environments and individual requirements of concrete construction, there are a variety of models of concrete placing machines to choose from, including:

• manual type: Reasonable design, stable and reliable structure, easy operation and flexible rotation.
• stationary: Specialized concrete pouring and placing equipment designed and produced for railroad girder yard, nuclear power and other engineering construction.
• mobile: Such as internal climbing, walking, ship-mounted, etc., with high flexibility and adaptability.

IV. Features and advantages

1. High efficiency: It can quickly and efficiently transport concrete to designated locations to improve construction efficiency.
2. High precision: It can achieve accurate fabrics, reduce waste and duplication of work, and improve construction quality.
3. High reliability: The use of advanced technology and high-quality components, with high reliability and stability.
4. Strong flexibility: Can flexibly adjust the angle and position of the fabric, suitable for a variety of different construction scenarios and complex construction environments.
5. High degree of automation: Reduce labor costs and labor intensity, and improve construction efficiency and quality.
6. Good safety: It has a perfect safety protection device to ensure the safety of the operator.

V. Application Scenarios

Concrete placing machines are widely used in various construction projects, such as:

• Pouring of buildings: Includes pouring of floors, walls, beams and columns.
• Pouring of road works: Such as pouring of pavement, curbs, drainage ditches and other parts.
• Pouring of bridge works: Such as pouring of bridge decks, piers, bridge barriers and other parts.

VI. Operating Procedures and Safety Precautions

When operating a concrete spreader, operating procedures and safety precautions should be strictly observed, including：

• Wear personal protective equipment before operation.
• Operate the equipment in strict accordance with the operating procedures, and do not make any adjustments during the normal operation of the machine.
• During equipment repair, maintenance, cleaning, and adjustment, the brakes must be stopped and locked first.
• The operator should be familiar with the working principle and operating procedures of the equipment, and have certain mechanical operation experience.
• Regularly inspect and maintain the equipment to ensure that the components are in good condition.

In summary, the concrete spreader is an indispensable kind of efficient, accurate and reliable concrete pouring equipment in modern construction and engineering.
