Aluminum alloy ladder, the length of the straight ladder should not exceed 6m, the full extension length of the extension ladder should not exceed 11m, and the limit device should be equipped to Make sure that the extended part and the non-extended part overlap by at least 1m. The organization shall inspect the newly purchased ladders before putting them into use, and shall regularly inspect and affix the inspection marks during the use period. At the same time, the ladder should be inspected before each use to ensure that it is always in good condition. Elevators, also called cargo elevators, are special cargo elevator products used to transport goods between floors of buildings, which are mainly used to transport goods up and down between floors; three-dimensional garages and underground garages are used to lift cars between floors.
The hydraulic system of the product is equipped with anti-falling and safety protection devices, and each floor and lifting platform work surface can be set and operated Button to achieve multi-point control. Ladder is a daily life tool, and the use of ladder allows people to reach a higher position. For example, if you want to change the bulb of an electric light at home, you can use a ladder to get to a place very close to the bulb, and the bulb can be replaced. For example, taking things on the top of a large closet cannot be done by yourself without the help of external force. You can reach and take things off with a folding ladder.
A foldable ladder is called a folding ladder. When you use it, unfold the ladder and the length of the ladder becomes longer. Fold up the ladder when you don’t need it, and put it in the storage room or the trunk of the car. It doesn’t take up much space. Aluminum alloy has low density, but relatively high strength, close to or exceeds high-quality steel, good plasticity, can be processed into various profiles, has excellent electrical conductivity, thermal conductivity and corrosion resistance, is widely used in industry, and its usage is second only to steel Some aluminum alloys can be heat treated to obtain good mechanical properties, physical properties and corrosion resistance.

Some aluminum alloys can To use heat treatment to obtain good mechanical properties, physical properties and corrosion resistance. The single ladder or herringbone ladder forms an angle of about 75 degrees with the ground. After extending the ladder, keep the overlapped part overlapped. The overlap distance of ladders under 8 meters should be more than 75 cm, and the overlap distance of ladders over 8 meters should be more than 110 cm.
When raising and lowering a ladder, you should hold the handle with one hand and the rope while lifting it. Do not place your palm on the ladder. On the stairs, otherwise you may get your fingers stuck when you lift the ladder. Lift to a suitable height. After making sure that the lifting clip is stuck to the step, pull off the fixed block at the bottom of the upper ladder and fasten the lifting rope. Open the ladder to a suitable width before use. Please lift gently when lifting Light down.
