Now there are many kinds of ladders. The unified structure when opened is generally a herringbone ladder or a straight ladder.
Large aluminum alloy double-sided telescopic slides (mechanical stamping) are mainly used for installation and maintenance Engineering

SST-60LHJ folded 3.30 meters , The deployment height of aluminum alloy herringbone ladder is 5.37 meters, bearing 150kg
SST-70LHJ retractable 3.90 meters, aluminum alloy herringbone ladder deployment height is 6.57 meters, load-bearing 150kg
SST-80LHJ collapsed 4.50 meters, aluminum alloy herringbone ladder deployed height 7.77 meters, bearing 150kg
How to use the herringbone telescopic ladder:
1. Unpack and check whether it is a genuine aluminum alloy double-sided telescopic slide
2. After confirming that it is correct, put the ladder to test the performance of the ladder.
The test method of aluminum alloy ladder is as follows;
[How to open]:
1. Step on the bottom step of the ladder with your feet, place your hands on the appropriate positions on both sides of the ladder, and hold the aluminum alloy telescopic ladder columns to Pull up.
2. After pulling up to a suitable position, fix the fixed rods on both sides to ensure the stability of the ladder.
1. When moving the ladder, do not hold the pedal when you are not sure whether the ladder will expand or contract. , You should hold the ladder column to avoid pinching.
2. When pulling the ladder, make sure that the two sides are fixed, so as not to affect the use of the ladder.
3. Use with caution for those who stay up late, are tired, drink alcohol, or are barefoot.
4. When the ladder is not in use, please place it horizontally.
Ladders remind you: No matter how good the ladder is, you must use it carefully and pay attention to the safety of climbing.Climbing step ladder
