Description

Technical Field

[0001] The utility model belongs to the technical field of boarding ladders, and in particular relates to an auxiliary stabilizing device for passenger boarding ladders. Background Art

[0002] A boarding ladder is a device used to lift passengers or cargo, providing passengers with convenient transportation up and down. The use of a boarding ladder can avoid passengers facing steep climbs such as ramps or stairs, and reduce the burden on luggage carriers, especially for the elderly and people with limited mobility. In order to ensure the safety of passengers, boarding ladders are usually equipped with anti-slip floors, guardrails, safety doors and other equipment to prevent accidental falls or slips.

[0003] When passengers board an aircraft via a boarding ladder or disembark after the aircraft lands, they need to first raise or lower the boarding ladder so that the boarding platform of the boarding ladder is located on one side of the cabin door. However, when the boarding ladder is raised or lowered by the lifting mechanism, most of its weight is supported by the hydraulic system. In the case of long-term operation, the hydraulic cylinder in the hydraulic system is easily damaged, thereby reducing the support stability, resulting in greater risks for passengers when checking in or disembarking. In view of this, the utility model is proposed to provide an auxiliary stabilizing device for passenger boarding ladders to solve the above problems. Utility Model Content
