Self-Leveling Tread Accommodation Ladder
Self-leveling tread accommodation ladder is a kind of ladder that can automatically adjust the level of steps according to the tilt Angle. It is commonly used on ships, along with accommodation ladder assemblies, as a way for crew and passengers to disembark and disembark. The ladder features the ability to automatically adjust the level of the steps to ensure that the steps are always level under different hull inclinations, providing a safer and more comfortable disembarkation experience.
Overview
Working Principle
The working principle of self-leveling tread accommodation ladder is mainly to use the structural characteristics of parallelogram. The following is a description of the working principle of a common self-leveling step ladder:
Parallelogram mechanism: the steps of the accommodation ladder, the tie rod and the ladder frame form a parallelogram four-bar mechanism. The tie rod connects the step and the ladder, and both ends are hinged with the auxiliary step platform.
Auxiliary step platform fixed: the auxiliary step platform is fixed on the side of the ship or other fixed structures, parallel to the ship deck.
Adaptive adjustment: When the height difference between the boat and the dock changes, the step will automatically adjust its Angle according to the principle of the parallelogram mechanism, and maintain the level. This adjustment is achieved through the articulation between the step and the tie rod, and the articulation between the tie rod and the ladder.
Limit relative position: The tie rod is mainly used to limit the relative position of the step, so that it is stable within a certain range.
Characteristics and Advantages
Here are some common features and advantages of Self-Leveling Tread Accommodation Ladder:
Automatic leveling function: The Angle of the step can be automatically adjusted according to the tilt of the hull, so that it is always level, reducing the risk of slipping and falling.
Safety: Provide stable access to and from the ship to ensure the safety of crew and passengers.
Comfort: Horizontal stepping makes getting on and off the boat more comfortable, reducing fatigue and discomfort.
Adaptability: Can adapt to different types of ships and different hull inclinations.

Conclusion
Overall, the Self-Leveling Tread Accommodation Ladder provides a convenient, safe and comfortable solution for ships to disembark and disembark, helping to improve the efficiency and safety of crew and passengers.
