Climbing the step ladder, in recent years, there have been frequent casualties caused by improper use and product quality problems, with tens of thousands of incidents every year.  It has become a tragedy for many families and society, but it is not difficult for us to find that most of the incidents during this period are completely preventable.  The users work on the swaying ladder every day, and use the ladder non-standard every day (even if they don't even understand what a standard ladder is).


Before use: Before each use, you must carefully check the surface of the product, parts, and rope   Check whether there are cracks, severe wear, and damage that affect safety; when using, choose a hard, flat ground to prevent the risk of side tilt; if the height exceeds 5 meters, be sure to set up a F8 or higher cable in the upper part of the product; check all ladders  Whether the feet are in good contact with the ground to prevent slipping; no other structures should be attached without permission, and the damaged product should never be used or repaired; when lifting, it is strictly prohibited to hold the cross brace to prevent cutting fingers.


According to the processing method, aluminum alloys can be divided into deformed aluminum alloys and cast aluminum alloys.  Deformed aluminum alloys are further divided into non-heat-treated reinforced aluminum alloys and heat-treated reinforced aluminum alloys.  The strengthened type cannot be heat-treated to improve its mechanical functions. It can only be strengthened by cold working deformation. It should include high-purity aluminum, industrial high-purity aluminum, industrial pure aluminum, and rust-proof aluminum.  Aluminum alloy ladders have low density, but relatively high strength, close to or exceed high-quality steel, good plasticity, can be processed into various profiles, have excellent electrical conductivity, thermal conductivity and corrosion resistance, are widely used in industry, and the amount of use is second only to  steel.


When the climbing tool is issued or retracted, the custodian must conduct a daily inspection; before use, use  If the climbing tool is damaged, the ladder foot sheath is broken, the pull wire is broken and falling off, the bamboo and wood materials are decayed, or the mechanical damage is detrimental to safety, you should immediately contact the manufacturer Shanghai Shenshi Metal Products Co., Ltd.  Repair, before repair, Do not continue to use.  The structure of any climbing equipment must be firm and reliable.


The use load of the pedal for the operator to go up and down should not exceed 1100N.  This is determined by multiplying 75ON of the weight of people and clothing by a load safety factor of 1.5.  When there are special operations on the ladder surface, and the weight on the pedal may exceed the above load value, the ladder pedal should be checked according to the actual situation.  If it is not suitable for use, it must be replaced or reinforced to ensure safety.  When using any ladder to go up and down, you must face the ladder, and no utensils are allowed in your hands.
