Basic Parameters
The pumping capacity of mainstream second-hand trailer pumps is usually between 40 and 90 cubic meters per hour, with a maximum horizontal conveying distance of approximately 300 to 600 meters and a vertical conveying height of up to 100 to 200 meters. The power system mostly adopts independent diesel generator sets, with a power range of 150 to 300 horsepower. The working pressure of the hydraulic system is maintained at 25 to 32 megapascals. The standard capacity of the hopper is 0.5 to 0.8 cubic meters, which can be adapted to the unloading of conventional mixer trucks. The total weight of the equipment is approximately 6 to 12 tons, meeting the standards for road transportation.
Main Features
Modular structure
The three major parts of the pumping system, power unit and chassis can be designed separately, highlighting the convenience of maintenance.
01
Economical configuration
The driving system omits the on-board pump, has a simpler structure, and reduces the number of failure points by approximately 40%.
02
Flexible pipe layout
Standard 125/150mm conveying pipes are adopted, and the pipe layout route can be flexibly adjusted through quick couplings.
03
Intelligent control
Retains the original factory pressure adaptive system and pipe blockage warning function, ensuring operational safety.
04
Core Advantages
Low investment threshold
The price is only 60% of that of the vehicle-mounted pump of the same specification, and no dedicated chassis vehicle is required for investment.
Superior maintenance cost
The hydraulic system has a simple structure, and the daily maintenance cost is more than 30% lower than that of the vehicle-mounted pump.
Strong site adaptability
Compact size is suitable for narrow construction sites, and the turning radius is about 25% smaller than that of truck-mounted pumps.
All functions are retained
Second-hand equipment usually fully retains the core pumping function, with performance degradation not exceeding 15%.
Functional Characteristics
Stable pumping
The double-cylinder hydraulic piston design ensures the continuity and uniformity of concrete transportation.
Pressure adjustable
Four levels of pumping pressure regulation are achieved through a hydraulic valve group, adapting to the transportation of concrete of different strengths.
Quick conversion
Equipped with dual operation modes of manual and remote control, the switching time does not exceed 3 minutes.
Safety protection
Retain basic safety devices such as overload protection and oil temperature monitoring to ensure reliable operation.
Typical Application Scenarios
New Rural Construction
Concrete pouring operations for low-rise residential houses and infrastructure.
01
Small-scale Municipal Works
Small-scale projects such as sidewalk paving and drainage ditches.
02
Factory Floor
Large-scale flat pouring for industrial warehouses, parking lots, etc.
03
Water Conservancy Projects
Construction of water conservancy facilities such as ditches and small DAMS.
04
Emergency Repair Projects
Emergency concrete transportation for road repair, bridge maintenance, etc.
