How to use the telescoping extension ladder？

When we construct a variety of engineering projects, we often use a variety of props, so how to use the telescoping extension ladder?

First, how to use the telescoping extension ladder

1. Give the ladder and the ground an angle of about 75 degrees.

2. After unfolding the ladder, ensure that the lap places are partially overlapping. Ladders with less than 8 meters should overlap more than 75 centimeters, and ladders with more than 8 meters should overlap more than 110 centimeters.

3. When lifting the ladder, hold the hand in one hand and the rope in the other hand. The palm can not be put down on the step of the ladder, otherwise the lifting and lowering will damage the fingers.

4. After rising to the appropriate height, make sure that the lift card is stuck in the ladder, fix the fixed block at the bottom of the upper ladder above, and then tie the lift rope, so that the ladder opens to the appropriate width can be used.

5. When the ladder drops, it is necessary to close both sides close, then untie the fixed rope, rise the ladder a little, let the card leave the ladder surface, and then drop slowly down. If the ladder does not go smoothly, you can hold the rope in one hand and slowly shake the ladder back and forth in one hand until it can drop smoothly.

Second, what is a telescoping extension ladder?

It is a category similar to the fishing rod, can freely stretch and shorten the ladder, common engineering and bamboo expansion ladder two categories, more easy to carry and store, can be placed in the closet, study, bed and the trunk of the car.

The shortened length is about 0.7 meters, the highest length after stretching is 4 meters, and the weight is between 6 and 10 kilograms, in the high construction, can bear the weight of 150 catties.

Summary: The above is some information about the telescopic ladder, from the above article we can see that it is a very convenient construction prop, good safety, excellent weight-bearing ability, convenient storage, convenient carrying, so it is widely popular with people. However, we must be in accordance with its use guidelines before the actual construction, so as to play the maximum efficiency, I hope to help you.
