Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of boarding ladders, and particularly relates to a marine boarding ladder. BACKGROUND

[0002] The marine boarding ladder is arranged at a boarding position of a lifeboat or a life raft, and is used for enabling personnel to safely board the lifeboat or the life raft which has landed on the water surface. When an emergency occurs on a ship and the ship needs to be abandoned, the marine boarding ladder is a key channel for enabling the personnel to safely transfer from a deck of the ship to the lifeboat or the life raft, and can ensure that the personnel remain stable during the climbing process and avoid falling into the sea, thereby ensuring the safety of the personnel.

[0003] The marine boarding ladder is generally made of wooden or aluminum alloy plates, and is composed of steps and side ropes. The steps and the side ropes are connected to each other in a stable manner through components such as a thimble, a lanyard and a grommet. The thimble at the end of the side rope is connected to the deck by using a shackle, and the marine boarding ladder is installed. The personnel can climb the marine boarding ladder. However, the side rope is soft and easy to bend, and the height of the marine boarding ladder is fixed. When the distance between the ship and the life-saving equipment does not completely match the height of the marine boarding ladder, the marine boarding ladder shakes too much during the climbing process of the personnel due to the influence of the stepping force or the wind force, and has great danger. Moreover, the marine boarding ladder greatly affects the psychology of the personnel and the transfer efficiency of the personnel. CONTENT OF THE UTILITY MODEL
