Ladders are becoming more and more widely used in life, but for novices, when they are used for the first time, they must learn the correct operation method, prohibit operation with brute force, and prevent damage to the folding ladder.
1. Unlock and extend the ladder column outwards, and hear a "click" sound while the lock block enters the position, indicating that the hinge has locked this position.
2. Unlock and pull the handle to open the lock, and at the same time, the lock block is retracted to the position, indicating that the hinge has been unlocked.At this time, the angle of the ladder column can be changed or the ladder can be folded.
If the handle cannot be pulled and the lock cannot be unlocked, this is because the hinge is forced to press the lock block.At this time, the ladder column can be pulled and shaken to release the external force.
3. After checking that the folding ladder is in use, please carefully confirm that all hinges are in the locked position before use. If there is a hinge with the lock block in position, you can open its symmetrical hinge and then retract the ladder column inwards by about 40 Degrees, and then spread out to lock the pair of hinges.
The folding ladder is a tool that helps us solve the ascending difficulty, which has important significance for engineering and life. However, when using it, we need to put our own safety first and use the folding ladder safely.
