The main oil cylinder is one of the most critical hydraulic components in concrete pump trucks and hydraulic pumping systems. It provides powerful reciprocating hydraulic force to ensure stable concrete conveying performance during continuous high-pressure pumping operations.
At Jiaheng Hydraulic, we manufacture high-performance main oil cylinders engineered for demanding construction environments and heavy-duty pumping applications. Our hydraulic cylinders are designed with precision machining, durable sealing systems, hard chrome plated piston rods, and high-strength cylinder tubes to ensure excellent reliability and long service life.
Our main hydraulic cylinders are widely used in:
Application Advantages
Efficient pumping capacity:
With high thrust (such as over 500kN) and long stroke (1500mm+) design, it supports concrete delivery of 60-150 cubic meters per hour, improving construction efficiency.
Pressure adaptability:
The working pressure can reach 25-35MPa, which can overcome challenges such as high concrete viscosity and long transportation distance, ensuring that the pumping process does not block pipes or stop.
Reliability and durability:
The anti fatigue design can meet the continuous operation requirements of more than 10 hours per day, reduce maintenance frequency (such as extending the seal replacement cycle to 6-12 months), and lower construction costs.
Intelligent adaptation:
It can be integrated with the intelligent control system of the pump truck, supporting real-time monitoring and adjustment of pressure and stroke, and adapting to the trend of automated construction (such as achieving precise pouring with BIM technology)
