Aluminum alloy ladder, the ladder user is responsible for checking the integrity of the ladder before using the mobile ladder. The inspection ladder should have a qualified label.  The HSE department is responsible for the supervision of the on-site mobile ladder.  With the continuous progress and development of society, the importance of safety work has become more and more important in the construction of market economy today. Therefore, most of the enterprises and institutions in our country have realized the importance of safe production.  Significantly, various driving safety education and training have been launched.  It is understood that in all safety accidents, the unsafe state of construction equipment is one of the main causes of accidents. Therefore, the safety performance of construction equipment determines the effectiveness of safety production management from the source and fundamentally.

When going up and down the ladder, the person must face the ladder and use the three-point contact climbing method (that is, using  With both hands and one foot, or one hand and both feet), only one person can stand on a single-wide ladder at a time.  Do not lean on one side, keep the center of gravity in the middle of the ladder, use the tool belt to carry the tool, or use the rope to hoist or hang the tool.  To ensure that there is no oil stains and mud on the bottom of the boots and the crosspieces, use the three-point contact climbing method at all times. If you must place a ladder in front of the door, lock or block the door first.  Mainly used in the manufacture of aviation equipment, daily necessities, doors and windows for construction, etc.

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 requirement for aluminum alloy ladders to be stable and durable is not only due to its meticulous product function division, but also due to its excellent product quality-focusing on the subtle level, more rational selection, can avoid danger.  In most cases, we should know that the weight of a portable metal herringbone ladder should not be less than 90 kg and should be marked according to the load of the herringbone ladder.  According to the carrying capacity, the rated load of the ladder can be divided into four levels.


IWe should be able to buy according to their own strength and according to different environments.  Bolt holes should be perforated or drilled precisely, and all holes should not be processed into large-scale burrs.  The thread should also expose at least 1.5 turns of the nut.  All nuts should be lock nuts or washers, or be tightened in an equivalent manner confirmed.  It is composed of continuous steps, platforms, and enclosure structures.  Generally wood is mainly used, metal stairs can also be considered, but the foot feel is not as good as wooden stairs. Home staircase balustrades are divided into wood, stainless steel, iron and stone, among which wood is more comfortable.

The foot of the bamboo ladder must be tied with a rubber with concave and convex grooves (such as car tires) to increase its friction  resistance.  Because the foot of the wooden ladder has a certain slope, it is necessary to keep the bottom surface of the foot parallel to the ground.  Ladder should be placed as far away as possible from doors and windows, corners or passage openings.  If you must work near the above-mentioned areas, roadblocks or warning signs should be set up nearby.  Make sure that there is no heat source and moisture near the ladder.
