Mobile platform elevators, in recent years, due to improper use and product quality problems, casualties have occurred frequently, with tens of thousands of incidents each 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).  According to the processing method, aluminum alloy can be divided into deformed aluminum alloy and cast aluminum alloy.  Deformed aluminum alloys are further divided into non-heat-treated reinforced aluminum alloys and heat-treated reinforced aluminum alloys.


The type that cannot be strengthened by heat treatment cannot be heat-treated to improve the mechanical function. It can only be strengthened by cold working deformation.  It should include high-purity aluminum, industrial high-purity aluminum, industrial pure aluminum, and anti-rust aluminum.  Cast aluminum alloys can be divided into aluminum-silicon alloys, aluminum-copper alloys, aluminum-magnesium alloys, aluminum-zinc alloys and aluminum-rare-earth alloys according to their chemical composition. Among them, aluminum-silicon alloys are simple aluminum-silicon alloys (not heat-treated for strengthening, low mechanical function, casting  Good function), especially aluminum-silicon alloy (heat treatment can be strengthened, high mechanical function, excellent casting function).


The insulation ladder uses high-temperature polymerization pultrusion manufacturing process, and the raw material is epoxy resin combined with pin technology.  The aluminum alloy material parts are treated with anodizing on the surface, and the shaft steel parts are coated with protective coating; the processed surface of the insulating laminated material parts is treated with insulating paint.  The ladder brace and the ladder foot anti-slip design are not easy to fatigue, the shape of each part of the ladder has no sharp edges and corners, the safety degree is high, the insulation function is strong; the water absorption is low, and the corrosion resistance is low.  When in use: definitely stop the work load beyond the ladder; the ladder foot has the anti-skid effect.


But there is still a need for someone to directly hold the ladder with their hands for maintenance (put the ladder sideways skewed together), and use  Step on the foot of the ladder to prevent the foot from moving; when climbing a ladder or working, always insist that your body is in the center of the ladder’s cross brace, and your body is upright and cannot be stretched outside, otherwise you may lose  BalanceMake an accident.  According to the processing method, aluminum alloy can be divided into deformed aluminum alloy and cast aluminum alloy.  Wrought aluminum alloy is divided into non-heat-treatable reinforced aluminum alloy and heat-treatable reinforced aluminum alloy.


The non-heat-treatable strengthened type cannot improve the mechanical properties through heat treatment, and can only be strengthened by cold working deformation.  Mainly include high-purity aluminum, industrial high-purity aluminum, industrial pure aluminum and anti-rust aluminum.  Heat-treatable reinforced aluminum alloys can improve mechanical properties through heat treatment such as quenching and aging. It can be divided into duralumin, forged aluminum, super-duralumin and special aluminum alloys.  To lower the ladder, close the two ends of the ladder closer, then untie the fixed rope, raise the ladder a little bit, make the fixed clip off the step surface, and then slowly descend.  If the descent is not smooth, you can hold the rope with one hand and gently shake the ladder back and forth with one  hand until the ladder descends smoothly.
