Main application scenarios
● Ships and Navigation: The most essential use, used for ship rigging, deck lifting, and anchor chain operations, is an important accessory for traditional wooden ships and modern fishing vessels.
● Lifting and hoisting: In construction, warehouse handling, and mining operations, ropes are used to lift heavy objects and change direction.
● Special working conditions: Due to the non-conductive and corrosion-resistant nature of wood, it is also used for electrical operations and traction operations in humid environments.
Core strengths
★ Wooden shell is non-conductive, corrosion-resistant, and suitable for humid and electrified environments.
★ Lightweight, easy to carry and install, very suitable for outdoor work.
★ Combining traditional wooden craftsmanship with metal reinforcement, balancing aesthetics and strength.
General service life (outdoor/marine environment+normal maintenance)
Lifespan range: 8-15 years
Core reason: Salt spray, rainwater, and especially seawater used for offshore operations can accelerate metal corrosion and wood moisture deformation. It is necessary to perform waterproof/anti-corrosion treatment every year, otherwise the service life will be significantly shortened.
