Flexible lifting and lowering Three section ladder Made of high-strength aluminum alloy

I. Product Overview
It is made of high-strength aluminum alloy. The ladder body is divided into two sections, the upper section and the lower section. The upper section is inserted into the lower section. During operation, it is limited by the support feet. The side plate of the upper section is equipped with a guide plate at the lower end, which facilitates the flexible lifting and lowering of the ladder and prevents it from tilting. The main components of the extension ladder include the upper section ladder, the lower section ladder and the lifting device. The lifting device is composed of nylon rope, pulley and support feet.
2. Application scope
It is used for rescue and disaster relief operations when climbing to rescue people or extinguish fires; especially in cities where there are no climbing vehicles, and the fire escape routes are narrow, climbing vehicles cannot reach the fire scene, while ordinary ladders cannot reach the required height at the scene, this ladder can be used in conjunction with fire fighting and can also be used for climbing maintenance and various climbing operations in factories, mines, multi-story buildings, etc.
