List of how to use fire ladder

Fire pull ladders are made of high-strength aluminum alloy and are mainly used in small and medium-sized cities without elevators and heights that cannot be reached by ordinary ladders. It is an indispensable tool for firefighters to climb up to rescue people and put out the fire. It can also be used for high-altitude operations in offices, factories, troops, electricians, shops, installers, and municipal construction workers. It can be seen that it has a wide range of uses. How to use the fire ladder? Next, let's learn about it together.
1. First, determine the approximate working height of the ladder according to actual needs, and then determine the position of the ladder on the ground. The distance between the position and the wall is about one-fourth of the required working height, and two support rods are extended to make the ladder tilt toward the wall, that is, the angle with the ground is about 75 degrees.
2. Pull down the drawstring. At this time, the middle ladder and the upper ladder will rise at the same time. After reaching the use height, loosen the rope upwards (be careful not to leave the rope at this time). At this time, the supporting feet will automatically be supported on the next ladder step, and the rope will be tied to any ladder step in the next section to increase the safety factor of the ladder, and the hand can leave the rope. Then hang the two support rods on the ground to make appropriate adjustments, and then support them back to the ground so that the entire ladder is close to the wall. At this time, the ladder protection personnel stand on the side against the wall to protect the ladder, so that it can be climbed.
3. When you need to descend after the work is completed, pull the rope downwards to raise the ladder about 15 cm, make the supporting feet leave the ladder pedals, and then slowly release the rope upwards, and the ladder will descend and contract. At this time, do not loosen the rope suddenly to avoid damage to the free fall of the ladder. The correct method is to loosen the rope alternately with both hands, so that the ladder is slowly lowered until it is fully retracted, and then the rope is tied to the ladder step.
