[0002] Fire ladders are important tools used by firefighters in climbing up to extinguish fires, climbing over obstacles, and rescuing people. According to their structural forms, they can be divided into single-bar ladders, hook ladders, two-section pull-up ladders, three-section pull-up ladders, and other structures. Different types of fire ladders are suitable for different scenarios. For example, single-bar ladders are small in size and light in weight, and are suitable for climbing in narrow places or indoors; hook ladders are lighter in weight, and firefighters can use windows, balconies, etc. to fix the ladder body with hooks, and climb upstairs to extinguish fires.
