A climbing ladder used on a ship-borne crane

Abstract

The invention discloses a climbing ladder for a shipboard crane and aims to solve the problem that a climbing ladder occupies large space on a ship, is likely to interfere with other equipment, and has large potential safety hazards in use. Only two foot bars are disposed the climbing ladder. Compared with an ordinary climbing ladder, the climbing ladder of the invention is greatly reduced in thenumber of foot bars and is lighter and more convenient. The climbing ladder is vertically hung on a crane vertical column, occupies little space and does not interfere with other equipment. In the whole process, two feet are inserted into the foot holes and are less likely to slide off the foot bars. The climbing ladder is safe and reliable. Even if the climbing ladder is tilted, the two feet cannot slip off the feet bars. The climbing ladder is relatively light, and is vertically hung on the crane vertical column, occupies little space and does not interfere with other equipment. During the use of the climbing ladder, the two feet are less likely to slide off the foot bars. The climbing ladder is safe and reliable to use.

Description

technical field [0001] The present invention relates to a climbing ladder, more specifically, it relates to a climbing ladder used on a ship-borne crane. Background technique [0002] At present, ships are generally equipped with climbing ladders, which can be used to board the ship or travel up and down at different heights on the ship. When not in use, the climbing ladders are usually placed on both sides of the ship, but because the climbing ladders are relatively heavy, they often hinder the ship. normal operation of other equipment. When the climbing ladder is used on a ship, due to the strong sea wind and waves, the climbing ladder will bump and tilt with the ship, and there is a greater safety hazard during the climbing process or when standing on the climbing ladder. Contents of the invention [0003] The invention overcomes the disadvantages that the climbing ladder on the ship occupies a large space, is easy to interfere with other equipment, and has a large pot...

Problems solved by technology

[0003] The invention overcomes the disadvantages that the climbing ladder on the ship occupies a large space, is easy to interfere with other equipment, and has a large safety hazard in the use of the climbing ladder, and provides a climbing ladder used on a ship-borne crane. Portable and vertically mounted on the crane column, it takes up little space and will not interfere with other equipment. During the use of the climbing ladder, the feet are not easy to slip off the pedals, and the use process is safe and reliable.
