Application scenarios

Concrete trailer pumps are engineering machinery that continuously transport concrete along pipelines to the pouring site through a hydraulic system.

They are widely used in the following scenarios:

1. Construction projects

High-rise building construction: transport concrete for high-rise buildings with more than 20 floors to solve vertical transportation problems (such as wall, floor, column pouring) and avoid the problem of low tower crane transportation efficiency.

Large venues and industrial buildings: Concrete pouring of large-span structures such as gymnasiums, factories, warehouses, etc. can be covered by long-distance pipeline transportation.

Foundation and foundation engineering: used for concrete pouring of foundation parts such as bridge piers, pile foundations, basement floors, etc., to ensure the continuous construction of large-volume concrete.

2. Infrastructure construction

Bridge and tunnel engineering: bridge piers, box beam pouring, tunnel lining concrete construction (such as subway tunnels, highway tunnels), especially suitable for areas with complex terrain and difficult for vehicles to reach directly.

Water conservancy projects: Concrete pouring of water conservancy facilities such as dams, reservoirs, and canals can be transported over long distances through pipeline extension in special environments such as rivers and mountainous areas.

Road and municipal engineering: Concrete pouring of urban road bases, construction of underground integrated pipe corridors, and concrete transportation of municipal bridges and culverts.

3. Special engineering scenarios

Construction in narrow spaces: such as urban village renovation, indoor mezzanine pouring, etc., the trailer pump can adapt to narrow sites through flexible pipe layout (no large pump truck is required to enter the site).

Disaster relief projects: Infrastructure repair after disasters such as earthquakes and floods can quickly transport concrete for emergency tasks such as dam reinforcement and road repair.

Model classification and pumping capacity

The models of concrete trailer pumps are usually divided according to parameters such as pumping pressure, theoretical delivery volume, motor power, etc. The common types and performance are as follows:

1. Classification by pumping method

Model type Representative model Theoretical pumping volume (m³/h) Pumping pressure (MPa) Applicable scenarios

Small trailer pumps HBT30, HBT40 30-40 6-8 Low-rise buildings, rural self-built houses, small projects

Medium trailer pumps HBT50, HBT60 50-60 8-12 High-rise buildings, bridge foundations, municipal projects

Large trailer pumps HBT80, HBT90 80-90 12-16 Super high-rise buildings, large bridges, water conservancy projects

Ultra-high pressure trailer pumps HBT120 100-120 16-20 Ultra-long distance delivery (such as tunnels, cross-river projects)

2. Classification by power type

Electric trailer pumps: use electricity as the power source, low noise, low pollution, suitable for areas covered by urban power grids (such as HBT60E, pumping capacity 60m³/h, pressure 10MPa).

Diesel trailer pump: powered by a diesel engine, highly maneuverable, suitable for areas without power grid or remote areas (such as HBT50D, pumping capacity 50m³/h, pressure 8MPa).

3. Key pumping capacity parameters

Horizontal delivery distance: ordinary models can reach 150-300 meters, and ultra-high pressure models can exceed 500 meters (such as HBT120 horizontal delivery distance of 600 meters).

Vertical delivery height: The vertical height of medium-sized trailer pumps is about 50-80 meters, and that of large trailer pumps can reach 100-150 meters. Ultra-high pressure models can cooperate with relay pumping to achieve more than 200 meters (such as super high-rise office building construction).

Investment and return analysis

1. Investment cost

Equipment purchase cost:

Small drag pump: 150,000-300,000 yuan (such as HBT30, suitable for rural market or small projects).

Medium drag pump: 300,000-800,000 yuan (such as HBT60, commonly used in mainstream construction projects).

Large/ultra-high pressure drag pump: 800,000-1.5 million yuan (such as HBT90, suitable for high-end projects).

Auxiliary costs:

Pipeline and accessories: about 50,000-100,000 yuan (steel pipes, hoses, elbows, etc. need to be configured according to the project distance).

Transportation and installation: The transportation fee for each transfer is about 2,000-5,000 yuan, and the labor cost for pipeline installation is about 500-1,000 yuan/time.

Maintenance and maintenance: The annual maintenance cost is about 10,000-30,000 yuan (hydraulic oil, replacement of wearing parts, etc.).

2. Profit and Return

Operation Charging Mode

Charging by Volume: In urban projects, the unit price of concrete pumping is about 20-40 yuan/m³ (depending on the conveying distance and height, such as high-rise pumping can reach 35-40 yuan/m³).

Charging by shift: The shift fee is about 1500-3000 yuan/day (8 hours), which is suitable for short-term, small-volume projects (such as self-built houses in rural areas).

Profit Case (taking the medium-sized HBT60 as an example)

Annual operation volume: Assuming 200 days of construction per year, the average daily pumping volume is 150m³, the unit price is 30 yuan/m³, and the annual turnover is: 200 days × 150m³ × 30 yuan/m³ = 900,000 yuan.

Annual cost: equipment depreciation (approximately 100,000 yuan per year, amortized over 5 years) + fuel consumption/electricity costs (approximately 150,000 yuan) + maintenance costs (20,000 yuan) + labor wages (2 drivers, approximately 120,000 yuan) + other costs (50,000 yuan), a total of approximately 440,000 yuan.

Annual net profit: 900,000 yuan - 440,000 yuan = 460,000 yuan, investment payback period is approximately 1.5-2 years (depending on the project saturation).

3. Risks and optimization suggestions

Risk points:

The project payment cycle is long and funds need to be advanced; the market competition is fierce and the unit price may be suppressed.

Optimization strategy:

Take on long-term large-scale projects (such as real estate projects and municipal bidding sections) and stabilize the workload;

Equip multiple equipment to form economies of scale and carry out leasing business at the same time (the leasing unit price is approximately 800-1500 yuan/day);

Establish long-term cooperation with concrete mixing stations and construction companies to reduce the empty driving rate.

Summary

With its efficient pumping capacity and flexible adaptability, trailer-mounted concrete pumps have become one of the core equipment for construction and infrastructure projects. Its investment payback period is relatively controllable, and it is especially suitable for professional pumping companies or large construction companies. When choosing a model, it is necessary to combine the target project type (such as high-rise/municipal/water conservancy), pumping requirements (volume, distance, height) and budget, and at the same time improve the stability of income by optimizing the business model (such as binding mixing stations and expanding leasing).
