Product Definition
Second-hand vehicle-mounted concrete pumps refer to concrete conveying equipment that has been put into use but still maintains a good working condition. They integrate the high-pressure pumping system with the vehicle chassis, featuring both mobility and efficient pumping capacity. This type of equipment usually has completed the main value depreciation in the second-hand market, and its price is only 40% to 60% of that of a new machine, making it an ideal choice for small and medium-sized construction enterprises.
Basic Parameters
The pumping capacity of mainstream second-hand equipment ranges from 60 to 120 cubic meters per hour, with a maximum horizontal conveying distance of approximately 500 to 800 meters and a vertical conveying height of up to 150 to 300 meters. The chassis mostly adopts six-wheel drive or eight-wheel drive heavy-duty trucks, with engine power ranging from 300 to 450 horsepower. The working pressure of the hydraulic system is maintained within the range of 28 to 35 megapascals, and the original intelligent distribution valve and pressure compensation system are retained. The capacity of the hopper is usually 0.6 to 1.2 cubic meters, which meets the unloading requirements of standard mixer trucks.
Main Features
Motorized pumping integrated
Integrating driving function and professional pumping system, it can start operation immediately upon arrival at the site.
01
Intelligent control system
Most devices retain the original factory's automatic adjustment of pumping displacement and fault diagnosis functions.
02
Modular design
The conveying pipes are connected with quick couplings, increasing the disassembly and assembly efficiency by more than 50%.
03
Multi-condition adaptability
By replacing the conveying cylinders with different pipe diameters, it can handle concrete of various strength grades from C10 to C80.
04
Core Advantages
Low comprehensive cost
The procurement cost is saved by more than 50% compared with new machines, and the remaining service life of the main hydraulic components usually reaches 60%.
Convenient for site transfer
Equipped with a built-in power driving system, no auxiliary equipment is required for transfer between construction sites.
Efficiency guarantee
Maintain the original designed pumping pressure and volume to meet the requirements of regular construction progress.
The maintenance system is mature
The market circulation of key components is sufficient, and the popularization of maintenance technology is high.
Functional Characteristics
High-pressure pumping
The maximum outlet pressure can reach 10-15 megapascals, making it suitable for the transportation of concrete in high-rise buildings.
Precise fabric
The fabric can be rotated 360 degrees through a remote control system, with a positioning accuracy of ±5 centimeters.
Automatic lubrication
Retain the centralized lubrication device to ensure the continuous normal operation of the conveying cylinder piston.
Safety monitoring
Equipped with material level sensors, oil temperature alarms and other devices to prevent operational risks.
Typical Application Scenarios
High-rise Buildings
The concrete pouring of the main structure can reach a height of over 200 meters.
01
Bridge Engineering
Continuous pouring of large-volume concrete for piers, box girders, etc.
02
Municipal Construction
Construction of underground structures such as comprehensive pipe galleries and metro tunnels.
03
Industrial Buildings
Flat pouring of large factory floors, equipment foundations, etc.
04
Special Projects
Special concrete transportation for reservoir DAMS, nuclear power plants, etc.
05
Maintenance Points
Daily cleaning
After each operation, the conveying pipes and hoppers must be thoroughly cleaned.
Regular maintenance
Replace the hydraulic oil filter element every 500 hours and check the wear condition of the conveying piston.
Winter protection
In cold seasons, the water tank should be drained and antifreeze added to protect the cooling system.
Long-term storage
Start and operate the hydraulic system monthly to prevent the aging and failure of seals.
