Trailer concrete pump

Types of trailer concrete pumps

A trailer concrete pump is a portable pump mounted on a trailer or skid and connected to a concrete pump truck. It is primarily used in construction projects that require small volumes of concrete to be precisely placed in hard-to-reach areas.

There are generally two main types of trailer concrete pumps based on their different working principles: line pumps and boom pumps. A third type of trailer concrete pump is the specialized usage pumps, which includes separate placing booms and special application pumps.

• Line pumps

A line pump for concrete is a flexible hose used to transport liquid concrete (or similar material) from the concrete truck to the placement location. It is a popular choice for small to medium-sized construction projects because of its simplicity, ease of use, and ability to maneuver in tight spaces. Line pumps typically support pumping distances ranging from 150 to 300 feet horizontally. They are also suitable for pumping concrete mixes with smaller aggregate sizes.

• Boom pumps

Boom pumps, also known as concrete pump trucks, are used for larger construction projects that require high volumes of concrete to be pumped quickly and precisely. They are mounted onto a truck or trailer, and their robotic arm can extend, place, and direct the flow of concrete with pinpoint accuracy. Boom pumps are known for their efficiency, speed, and ability to reach high and far distances. They are capable of pumping hundreds of cubic yards of concrete per hour and can easily reach over obstacles like buildings and other structures. This makes them ideal for projects like high-rise construction, bridges, and large foundations.

• Special application pumps

Special application pumps offer some unique advantages and are suitable for specialized projects. For instance, separate placing booms are designed to be mounted on a structure's framework, which allows for precise placement of concrete in high-rise buildings. Another example is shotcrete pumps, which are specifically designed for spraying wet concrete (shotcrete) at high velocity onto surfaces. This is commonly used in applications like tunnel lining, slope stabilization, and architectural concrete finishes.

Specification and maintenance of a trailer concrete pump

These are the specifications that one should consider when getting a concrete pump.

• Pumping capacity: This is the maximum concrete output that can be achieved by the pump in a given time (usually expressed in cubic meters per hour). Different concrete pumps have different pumping capacities. For example, a trailer concrete pump may have a pumping capacity ranging from 40 to 100 cubic meters per hour, while a larger truck-mounted concrete pump can reach higher capacities.
• Reach: This is the horizontal and vertical distance that the concrete pump can reach. It is usually measured in meters. The reach of a concrete pump is important for accessing and placing concrete in different construction sites. For instance, some trailer concrete pumps have a reach of about 20 to 50 meters, which makes them suitable for small to medium-sized projects.
• Power source: Concrete pumps are powered by different sources such as diesel engines, electric motors, or hybrid systems. The type of power source affects the mobility and performance of the concrete pump. For example, a diesel-powered concrete pump provides greater mobility and can be used in outdoor or remote construction sites without access to electrical power.
• Pipeline diameter: The size of the concrete pumping pipeline affects the flow and pressure of the concrete being pumped. The diameter of the pipeline is usually expressed in millimeters (mm). Larger diameter pipelines can handle higher volumes of concrete and are more suitable for high-pressure pumping. For example, a trailer concrete pump may have a pipeline diameter of 100-200 mm, depending on the specific model and design.

For a concrete pump to work efficiently and last long, it needs proper maintenance. Regular maintenance is crucial for keeping the concrete pump in optimal working condition and ensuring safety on construction sites. Here are some tips for maintaining a concrete pump:

• Follow the manufacturer's maintenance schedule and guidelines for routine inspections and servicing.
• Check and lubricate all moving parts, including the hydraulic system, pistons, seals, and bearings.
• Inspect the concrete pumping pipeline for any signs of wear, blockages, or leaks. Clean the pipeline after each use to prevent buildup and maintain proper flow.
• Monitor the condition of the pump's filters and replace them as needed to ensure clean and efficient operation.
• Keep the concrete pump clean by removing any concrete buildup or debris after each use. This helps prevent clogs and reduces strain on the pump components.
• Train operators on proper operating procedures and safety practices to avoid damage to the pump and ensure safe operation.
• Avoid overloading the pump beyond its rated capacity and reach.
• Store the concrete pump in a dry and secure location when not in use to protect it from the elements and unauthorized access.

Scenarios of trailer concrete pumps

Trailer concrete pumps are used in a wide range of construction projects that require the precise placement of liquid concrete. They are used in scenarios such as the following:

• High-rise Construction:

Trailer concrete pumps are commonly used in high-rise building projects, such as skyscrapers, residential towers, and office buildings. The flexible boom can easily reach great heights, allowing concrete to be precisely placed on upper floors, columns, and other structural elements.

• Bridge and Tunnel Construction:

In bridge and tunnel construction, trailer concrete pumps are ideal for pouring concrete in tight or hard-to-reach locations. They can navigate through confined spaces and reach across obstacles, enabling efficient concrete placement for the foundation, decks, abutments, and other components.

• Infrastructure Projects:

Trailer concrete pumps are also used in infrastructure projects, such as roads, dams, airports, and water treatment facilities. They provide a precise and controlled concrete placement method for various infrastructure elements, including road barriers, dam walls, airport runways, and water treatment tanks.

• Residential Construction:

In residential construction projects, such as single-family homes, multi-family complexes, and housing developments, trailer concrete pumps are commonly used for pouring foundations, slabs, walls, and other structural elements with accuracy and efficiency to ensure quality and consistency throughout the construction process.

• Decorative Concrete Applications:

In addition to structural projects, trailer concrete pumps are also suitable for decorative concrete applications, such as stamped concrete patios, exposed aggregate driveways, and stained concrete walkways. They offer a precise and controlled method for placing decorative concrete finishes in place.

• Rural and Remote Construction:

Trailer concrete pumps are versatile equipment that can be used in various construction scenarios. Whether in urban areas with limited access or rural locations, their mobility and reach make them suitable for a wide range of projects, from small-scale residential construction to large-scale infrastructure development.

How to choose a trailer concrete pump

When selecting a trailer concrete pump, it is important to consider the following factors.

• Pump capacity: This is the amount of concrete the pump can deliver per unit of time. It is usually measured in cubic meters per hour (m3/h). When choosing a concrete pump, be sure to select one that matches the required project volume. For larger projects, a high-capacity concrete pump is often the best choice because it can speed up the construction process. Conversely, for smaller projects, a pump with a lower capacity may be sufficient, and it may be more economical to use a smaller pump.
• Maximum pumping distance and height: This refers to the maximum horizontal distance the concrete pump can transport concrete and the maximum vertical height it can reach. The pumping distance and height of the concrete pump mainly depend on the length of its boom. When choosing a concrete pump, consider whether the project requires a specific pumping distance or height. Ensure that the selected pump has a boom length and configuration that can meet the project's needs. For example, for high-rise construction, a concrete pump with a longer boom is required to reach greater heights.
• Power source and engine type: The power source of a concrete pump is often either electric or diesel, and engine types are divided into motor engines and combustion engines. Electric concrete pumps are usually used for indoor projects or areas with strict noise and emission requirements, while diesel concrete pumps are more suitable for outdoor projects. Therefore, depending on the project's environmental requirements and site conditions, it is important to choose the appropriate power source and engine type for the job.
• Additional features: Consider other features of the concrete pump, such as the control system, safety devices, and accessories. A good control system can improve the operation efficiency and accuracy of the concrete pump. Safety devices, such as outriggers and boom anti-collision systems, can ensure the safety of the operation. Also, the availability of accessories and spare parts for the concrete pump is important for maintenance and repair.
