Cylindrical Underwater Lifting Bags Reliable Efficient And Durable Solutions for Heavy Marine Lifting
Jiangsu, China – October 2025 – Hongruntong Marine, a leading manufacturer with over 30 years of experience in marine equipment production, including mooring bollards, has released an in-depth knowledge sharing piece on cylindrical underwater lifting bags. These lifting bags are a key tool in underwater operations, providing safe, efficient, and reliable lifting solutions for marine engineering, salvage, and construction projects.
Cylindrical underwater lifting bags are inflatable devices designed to lift, float, or stabilize submerged objects such as sunken vessels, heavy machinery, or large structural components. Constructed from high-strength synthetic rubber reinforced with multiple layers of steel wire rope, these lifting bags provide excellent load-bearing capacity while maintaining flexibility and durability in harsh underwater environments. Their cylindrical shape ensures uniform load distribution and stability during lifting operations, reducing the risk of tilting or imbalance.
“Over the past three decades, Hongruntong Marine has specialized in designing and manufacturing high-quality marine equipment,” said a company spokesperson. “Our experience with mooring bollards has given us extensive knowledge of marine loads and materials, which we apply to the production of underwater lifting bags to ensure maximum safety, efficiency, and durability.”
Key features of cylindrical underwater lifting bags include:
High Load Capacity: Designed to lift heavy objects underwater safely.
Durable Construction: Multi-layer reinforcement resists punctures, abrasion, and long-term wear.
Corrosion Resistance: Materials withstand prolonged exposure to seawater and harsh underwater conditions.
Easy Operation: Can be inflated and deflated quickly for controlled lifting and positioning.
Applications for these lifting bags range from underwater salvage operations and bridge construction to offshore platform installation and heavy marine logistics. Their modular and flexible design allows multiple bags to be combined for lifting extremely heavy loads, offering marine engineers a versatile solution for a variety of projects.
By sharing technical insights and operational tips on cylindrical underwater lifting bags, Hongruntong Marine aims to educate the industry and promote safer and more efficient underwater lifting practices. The company continues to invest in R&D, ensuring that its lifting solutions meet international safety standards and perform reliably in demanding marine environments.
