Crane Luffing Hydraulic Cylinder

As a Chinese manufacturer and supplier with 20 years of experience in the hydraulic field, Raydafon's independently developed crane luffing hydraulic cylinder integrates an intelligent load matpriching system, dynamically adjusts the 3000kN thrust output in real time, and cooperates with aviation-grade forged cylinders and micron-level precision servo control to ensure stable operation under harsh working conditions such as ports and wind power. The triple seal protection design resists salt spray and dust erosion, and the 5000-hour maintenance-free cycle significantly reduces operation and maintenance costs. It is the preferred solution for domestic and foreign engineering equipment manufacturers to improve operating efficiency. Raydafon provides highly competitive prices in a direct sales model - the cost of products with the same performance is only 60% of that of European and American brands, and supports full-specification customization of cylinder diameters from 50 to 500mm.

Product Features

1. Full-condition adaptive load control technology

The cylinder forging process of Raydafon crane luffing hydraulic cylinder is derived from aviation-grade material technology. It uses customized high-strength alloy steel, which is double-aged after seven die forging processes to stabilize the tensile strength of the material at more than 1250MPa.

2. Micron-level precision servo control solution

In the field of precision control, our engineering team has broken through the bottleneck of traditional valve control systems and developed an integrated electro-hydraulic servo module. This valve group independently designed by Raydafon uses aviation-grade servo valve cores and a magnetostrictive displacement sensor with an accuracy of ±0.03mm to achieve ultra-low-speed stable operation of 0.08mm/s.

3. Extreme Environment Long-life Protection System

For harsh working conditions such as salt spray erosion of port machinery and high-temperature dust of metallurgical equipment, we have built a triple progressive sealing protection structure: the main seal uses a perfluoroether rubber composite seal ring imported from Germany, and the double-lip design realizes two-way pressure compensation; the stepped dust lip of the middle layer can effectively intercept solid particles larger than 5μm, which is 40% higher than the traditional single-lip seal in terms of anti-pollution ability.

4. Energy-efficiency optimized hydraulic system design

Raydafon's breakthrough in energy-saving technology comes from an in-depth analysis of the operation cycle of construction machinery: the innovative differential amplitude circuit can reduce the hydraulic oil circulation volume by 35% under no-load conditions, and with the high-efficiency permanent magnet synchronous motor pump group, the system's comprehensive energy consumption is reduced by 28% compared with the traditional solution.
