Boat Lift Helper is a specialized buoyancy-assisted lifting device designed to support underwater lifting, vessel recovery, and marine construction operations. Built with reinforced industrial fabrics and advanced marine protective coatings, the system delivers reliable buoyant lifting force while maintaining structural durability in harsh marine environments.
The robust material construction ensures excellent resistance to saltwater corrosion, mechanical abrasion, and long-term exposure to sunlight and varying water temperatures. Available in multiple lifting capacities and structural configurations to meet different vessel sizes and marine engineering requirements.
A coastal harbor authority faced a challenging situation when a 30-meter fishing vessel partially sank near the entrance channel after storm damage. The recovery team deployed several Boat Lift Helper units along both sides of the vessel's hull. Divers positioned the units beneath submerged sections and gradually inflated them to create controlled buoyancy.
The vessel slowly regained flotation stability, allowing the salvage crew to pump out water and restore buoyancy without sudden structural stress. The operation was completed within a single working day, minimizing port traffic disruption and significantly reducing recovery costs.

Note: Other sizes can be customized according to requirements.
Engineered to provide reliable buoyant lifting force through carefully designed structure that distributes internal pressure evenly. Reinforced fabric structure with advanced sealing technology ensures consistent buoyancy output during underwater lifting operations.
Constructed from high-strength industrial fabrics developed for marine environments. Multiple protective layers enhance abrasion resistance and prevent damage from contact with vessel hulls and underwater structures.
Flexible structural design adapts to wide range of hull shapes and underwater structures. Conforms to curved surfaces and uneven contact areas to provide stable lifting support for fishing vessels, workboats, and cargo ships.
Lightweight yet durable structure simplifies transportation and handling. Controlled inflation system allows operators to adjust buoyancy gradually for precise lifting control during complex marine operations.
