As the core actuator of the hydraulic transmission system, the single-acting high-tonnage locking nut hydraulic cylinder occupies an important position in industrial fields such as heavy lifting, bridge construction, and shipbuilding due to its excellent performance. The following is a comprehensive analysis of the product from the aspects of technical parameters, core advantages and application scenarios.
1. Overview of product parameters
Tonnage range: 50 tons to 800 tons, which can meet the needs of multiple scenarios from light handling to ultra-heavy equipment installation.
Stroke capacity: 50-300mm, suitable for narrow space operations, taking into account flexibility and operation accuracy.
Maximum working pressure: 700bar (10,000psi), high-pressure design ensures stable output under large loads.
Structural characteristics: single-acting configuration, hydraulic drive thrust direction is controllable, return stroke depends on gravity or external force, energy-saving and efficient.
2. Analysis of core advantages
Safety locking technology
The locking nut mechanical locking design is adopted. After the hydraulic disconnection, the nut automatically locks the load to avoid accidental slipping due to pressure fluctuations or misoperation, greatly improving the safety of operation. The optimized design of the guide surface can absorb the impact of eccentric loads and prevent piston overshoot.
Compact and durable
The ultra-thin structure has a reduced height and is suitable for narrow installation space, especially for scenes such as port machinery and tunnel excavation.
All components are treated with Nitrox ONC anti-corrosion and painted surface to withstand extreme temperatures (-40℃ to +200℃) and corrosive environments.
Efficient maintenance and customization
Equipped with quick connectors (CR-400 standard) and dust caps, maintenance is convenient; the overflow hole design also has a stroke limit function.
Customized production is supported, and the cylinder geometry, sealing materials, etc. can be adjusted according to customer needs to meet special working conditions.
3. Typical application scenarios
Heavy lifting and handling: Port cranes, steel plant equipment relocation and other scenarios that require large tonnage and stable lifting.
Bridge and steel structure construction: support bridge erection, heavy steel component installation, and ensure high-altitude operation safety.
Ship and energy equipment: high-load operations in marine environments such as ship deck machinery and offshore wind power installation platforms.
4. Safety certification and reliability guarantee
All products have passed ISO 9001 quality management system certification and have undergone rigorous testing, including:
Anti-eccentric load test: Verify the sealing performance and structural strength under lateral force.
Fatigue life test: simulate millions of cycle conditions to ensure long-term stable operation.
5. Customer value and customized services
Efficient return on investment: Compared with traditional double-acting cylinders, single-acting design reduces energy consumption and maintenance costs.
Quick response support: Provide 24-hour technical consulting services, and provide on-site working condition simulation and optimization solutions according to project requirements
