Construction Hydraulic Cylinders
Patent technology of anti-leakage
The representative of concrete machinery is the pump truck, hydraulic cylinders can be classified as boom, support, and pumping according to their function. During the operation, the boom and leg cylinder will be subjected to vibration, lateral loading, and the need to maintain pressure. The master pumping cylinder runs fast, the impact is large, and the front end is immersed in water, which requires high reliability of the hydraulic cylinders.
Overview
Features
1. Single-cylinder bolt interlocking technology can ensure the reliability and safety of the lifting arm during expansion and hoisting;

Pump Truck Hydraulic Cylinder Industry knowledge
1. What is the core role of the Pump Truck Hydraulic Cylinder in a concrete pump truck?
The Pump Truck Hydraulic Cylinder is a vital component of a concrete pump truck, mainly used to drive the boom and concrete pumping system of the pump truck. As an important mechanical equipment in construction, the core function of a concrete pump truck is to transport concrete to the designated location of the construction site through a high-pressure pipeline, and this process is completely dependent on the power support provided by the hydraulic cylinder. In the work of the pump truck, the hydraulic cylinder precisely controls the angle and extension of the boom to ensure that the concrete can be pumped accurately and efficiently.
In a concrete pump truck, the hydraulic cylinder is subjected to high-frequency loads and long-term high-pressure work. Therefore, the design of the hydraulic cylinder must have high strength, high wear resistance and good fatigue resistance. Hengcai Hydraulic Cylinders, with its deep technical accumulation in the field of hydraulic systems, provides powerful power support for the hydraulic system of the pump truck. During the working process, Hengcai's hydraulic cylinder can stably complete the lifting, extension and adjustment of the boom, ensure the stability and accuracy of the pumping process, thereby improving construction efficiency and engineering quality.
2. The working environment of the hydraulic cylinder of a pump truck is often full of challenges
The hydraulic system not only needs to handle high loads, but also needs to cope with harsh working conditions.
The hydraulic cylinder of a concrete pump truck needs to have extremely high durability and reliability in a high-load, high-frequency working environment. Hengcai Hydraulic Cylinders has done a lot of research and optimization in this regard with its years of technological accumulation and innovation, so that its Pump Truck Hydraulic Cylinder can cope with the frequent use of pump trucks under high loads and ensure its long-term stable operation.
In order to meet the challenges of high loads, Hengcai uses special high-strength alloy steel materials, which are heat treated and surface hardened to significantly improve the fatigue resistance and wear resistance of the hydraulic cylinder. This material can withstand long-term, high-load repeated work without material fatigue or structural damage, greatly extending the service life of the hydraulic cylinder.
In terms of structural design, Hengcai has optimized the various components of the hydraulic cylinder so that it can maintain excellent performance under high load conditions. The friction inside the hydraulic cylinder is minimized, which reduces energy loss and improves work efficiency. In addition, the sealing system and anti-corrosion design of the hydraulic cylinder enable it to maintain efficient and stable working conditions during frequent operations.
With the improvement of environmental protection requirements, the sealing and oil management of hydraulic cylinders in pump trucks have also become the focus of design. Hengcai pays attention to the environmental performance of hydraulic cylinders and adopts materials and designs that meet environmental protection standards to ensure that the hydraulic cylinders will not leak pollutants during operation, ensuring the cleanliness of the hydraulic system and the sustainability of the environment. This environmentally friendly design not only conforms to the development trend of modern industry, but also provides customers with longer-term cost benefits.
