Swivel lifting points are versatile and essential components used in various lifting and rigging operations across Australia. Here's an overview of their uses and key features:
Applications
- Swivel lifting points are widely used in:
- Manufacturing industries
- Construction projects
- Concrete and precast industries
- Automotive sector
- Mining operations
- Oil and gas industry
- Power and utilities
- Transportation and logistics
- Entertainment industry (e.g., stage rigging)
Key Features and Benefits
360° Swivel and 180° Pivot
Swivel lifting points offer full 360-degree rotation and 180-degree pivot functionality. This allows for multidirectional lifting without compromising load integrity, making them ideal for handling loads that need to be rotated or positioned precisely
Versatility
These lifting points can be used in various lifting and lashing applications, adapting to different load requirements and rigging setups
Safety Enhancement
The swivel design prevents twisting and binding of slings, significantly reducing the risk of accidents during lifting operations
High Load Capacity
Swivel lifting points are typically rated for higher loads compared to traditional eyebolts, making them suitable for heavy lifting applications. They are available in various working load limits, ranging from 0.3 to 20 tonnes
Durability and Reliability
Manufactured from high-strength materials like forged alloy steel, these lifting points undergo rigorous testing, including proof testing, break testing, and magnaflux crack detection, ensuring long-lasting performance and reliability
Advantages Over Traditional Eyebolts
- Holds the same workload in all lifting angles and directions
- Internal retention spring allows lifting eye to be put in pre-load positions
- Self-aligns as the load is applied to prevent twisting and binding
- Higher load capacities over standard-rated eyebolts
- Long factory full thread bolt to allow for custom lengths of thread when needed
- Smooth galvanised anchor bolt to allow resistance to corrosion and rust fatigue
Best Practices
To ensure safe and effective use of swivel lifting points:
- Conduct regular inspections for wear, corrosion, or damage
- Ensure proper installation according to manufacturer guidelines
- Perform load testing and comply with industry standards
- Consider environmental factors when selecting lifting points
- Consult with rigging experts for complex lifting scenarios
In conclusion, swivel lifting points are crucial components in Australian lifting and rigging operations, offering enhanced safety, versatility, and efficiency across various industries.
The surface treatment process of zinc-nickel alloy generally includes the following steps:
1. Degreasing Treatment: This is an important pre-plating step aimed at removing grease and other contaminants from the workpiece surface to ensure good adhesion between the coating and the substrate.
2. Acid Activation Treatment: Acid washing is used to remove the oxide layer on the workpiece surface, increasing surface activity and facilitating metal deposition in the subsequent electroplating process.
3. Zinc-Nickel Plating: Under specific electroplating conditions, such as controlled current density, temperature, and time, a zinc-nickel alloy layer is deposited on the workpiece surface. This is the core step of the entire process.
4. Pre-Soaking: Pre-soaking treatment before or after electroplating helps improve the quality and adhesion of the coating.
5. Brightening Treatment: A hydrochloric acid solution is used for brightening to enhance the appearance and gloss of the coating.
6. Passivation Treatment: The workpiece is treated with a specific passivation agent to improve the corrosion resistance of the zinc-nickel alloy coating. This process can be performed at room temperature with strict control of time and conditions.
7. Cleaning and Drying: Finally, the plated workpiece is thoroughly cleaned to remove residual chemicals, then dried and stored.
