As a Chinese manufacturer, Raydafon produces crane counterweight hydraulic cylinders, which are the core of the equipment counterweight system. When the boom is extended, it is like an "invisible weight", which stabilizes the center of gravity by precise balance adjustment, making the lifting more stable, reducing the situation of imbalance and downtime from the root, and directly improving construction efficiency. Our factory direct supply products have price advantages, and can adjust the force in real time according to the working conditions, with fast response and high precision, saving more than 15% energy consumption compared with traditional cylinders at the same strength.
As a Chinese manufacturer, Raydafon's crane counterweight hydraulic cylinder is made of high-strength alloy steel, which is resistant to high pressure and heavy loads. It is not easy to deform even if it carries heavy objects for a long time. The surface of the cylinder is treated with special chrome plating or anti-corrosion coating, which can cope with outdoor humid, salt spray or dusty environments. It is not easy to rust or wear after three to five years of use, and its service life is far longer than that of ordinary cylinders.
2. Precise control
This product works well with the hydraulic control system, and there is almost no sense of frustration when telescoping. Whether it is quickly adjusting the counterweight position during lifting or millimeter-level balance adjustment during fine lifting, it can be accurate and correct. The vibration and impact during the operation of the equipment are significantly reduced, the operation is smooth, and it can also protect other parts of the crane in disguise, saving a lot of maintenance costs.
3. Simple installation and maintenance
The modular design can be installed on the crane without large-scale disassembly and modification. It can be fixed by just twisting a few fixing points, which saves half the installation time compared to traditional cylinders. The seals and maintenance ports are humanized, and parts can be replaced with just a wrench. Even in the muddy environment of the construction site, maintenance can be completed within half an hour without delaying the progress of the project.

Product Application
1. Port container loading and unloading:
At the port terminal, Raydafon crane counterweight hydraulic cylinder can be called the "stabilizing force" of container loading and unloading. When the shore container crane grabs a 30-ton container, this cylinder is like an invisible balancer. By adjusting the angle of the counterweight block in real time, the crane arm dozens of meters high can always remain stable when it is extended and retracted. There was a port test: when using traditional cylinders, the container will shake by ±5° when hoisting on windy days. After switching to Raydafon's hydraulic cylinder, the shaking amplitude is directly controlled within ±1°, which not only improves the lifting efficiency by 20%, but also eliminates the collision loss of containers caused by imbalance.
2. Heavy lifting at construction sites
The tower crane operation at the construction site is the most challenging for the adaptability of the equipment. Raydafon's Products are particularly useful in super-high-rise construction - when the tower crane transports steel bar bundles to a height of 200 meters, the cylinder will automatically adjust the counterweight force according to the extension length of the boom. A construction team once reported that when pouring high-rise floor slabs, it is necessary to frequently adjust the boom angle to transport concrete pump pipes. The response speed of this cylinder is 3 times faster than that of the old equipment. There has never been a single equipment shutdown due to counterweight lag, which has shortened the construction period of a building by 15 days.
3. Heavy manufacturing equipment installation
In the heavy equipment installation scenario, precision is the lifeline. When a wind power equipment factory installed a 70-meter-high wind turbine tower, our product was used in conjunction with a hydraulic control system to achieve "millimeter-level leveling" - when the tower was hoisted into the air, the cylinder could fine-tune the position of the counterweight block according to the sensor data to ensure that the verticality error of the tower did not exceed 2 mm. Compared with the traditional mechanical counterweight method, not only the installation efficiency is improved by 50%, but also the manual repeated calibration process is eliminated, and the installation cost of a single fan is directly saved by 8,000 yuan.
