Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bulk carriers, in particular to a boarding ladder for a bulk carrier. Background Art
[0002] Bulk carrier refers to a general term for ships that transport large quantities of dry bulk cargo such as grain, coal, ore, salt, cement, etc. Bulk carriers have a single type of cargo and do not need to be packed into bundles, packages, or boxes for loading and transportation. The cargo is not afraid of being squeezed. After the cargo is loaded into the cargo hold, it can be transported on the sea. Bulk carriers have large carrying capacity, large tonnage, and good economy, and they occupy a large proportion in the field of maritime transportation.
[0003] A bulk carrier's boarding ladder is usually a sturdy, durable piece of equipment used for crew, staff or visitors to board and disembark from the ship. These boarding ladders are usually designed with safety, comfort and ease of use in mind.
[0004] A common bulk carrier boarding ladder is a telescopic boarding ladder, which has the following features:
[0005] Telescopic: This boarding ladder can be telescoped to the appropriate length to adapt to different ship heights and dock heights.
[0006] Stability: They are usually made of strong materials and structures to ensure stability during boarding and disembarking.
[0007] Portability: Some boarding ladders are designed to be removable or foldable for easy transfer between ships or storage.
[0008] These boarding ladders can be manually operated or automatically operated, depending on the needs and size of the vessel. When installing and operating these boarding ladders, it is usually necessary to comply with relevant safety standards and operating guidelines to ensure the safety of personnel and the effective operation of the equipment.
[0009] When the existing boarding ladder of a bulk carrier is in use, although people can board the ship normally and there are handrails, the handrails are not safe and are not easy to disassemble, resulting in inconvenience when the handrails are damaged or repaired or replaced. In addition, the cargo ladder does not have an anti-collision device, which reduces the practicality of the device.
