Marine Accommodation Ladder

Marine Accommodation Ladder

An accommodation ladder is a portable flight of steps down a ship's side. Accommodation ladders can be mounted parallel or perpendicular to the ship's board. If the ladder is parallel to the ship, it has to have an upper platform. Upper platforms are mostly turnable. The lower platform (or the ladder itself) hangs on a bail and can be lifted as required. To prevent damage to boats going under the ladder as the water level rises and falls, a boat fender is fitted to the end of the ladder. The ladder has handrails on both sides for safety. Accommodation ladders are constructed in such a way that the steps are horizontal whatever the angle of inclination of the ladder.

parts

Configuration Selection

part	material	feature
Ladder frame	AL Alloy LF5	Light weight, anti-corrosion, nice appearance but not fireproof
	Q235-A	Good welding performance, Good toughness. But relatively heavy and easy to rust and corrode. After hot-dip galvanizing treatment, the anti-rust and anti-corrosion performance is greatly improved, but the surface finish is difficult to improve, which affects the appearance of the surface.

Comparison Differences

Other manufacturers’ low quality accommodation ladder	Hi-Sea high quality accommodation ladder
1. The material of the accommodation ladder has a high impurity content, is brittle, has low strength and is easy to break, has a short service life, and is prone to safety hazards. 2. The surface of the accommodation ladder is not properly treated, and it is easy to be rusted and damaged. 3. The accommodation ladder has not passed the load test, and there is no safety guarantee when using it. 4. The welding process of each part is poor, and it is easy to be damaged during use, affecting the service life and causing personal safety hazards. 5. The handrail rope is thick and hard, the friction is too large, and the user experience is not good.	1. The accommodation ladder material is made of high-quality aluminum alloy, which has high strength and light appearance, and is also corrosion-resistant and has a long service life. 2. The aluminum parts are anodized, with strong corrosion resistance, convenient maintenance and low cost. 3. The handrail rope is made of high-strength nylon fiber, with a compact structure, good flexibility and impact resistance, as well as wear resistance, UV resistance and corrosion resistance. 4. After passing the inspection of classification society, CCS, ABS, BV and other classification society certificates can be issued, and the quality is guaranteed. Implement standard CB/T 14360-93
