Mobile platform ladder When in use: It is absolutely forbidden to exceed the specified work load; the ladder feet have a non-slip effect. However, there is still a need for someone to directly support with their hands for protection (while preventing the ladder from sideways), and step on the foot to prevent the foot from moving; when climbing, keep your body in the middle of the ladder's cross brace. Keep your body upright and cannot stretch out, otherwise you may lose your balance and cause accidents.
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. The aluminum alloy ladders supplied are divided into two categories: cast aluminum alloy, which is used in the as-cast state; deformed aluminum alloy, which can withstand pressure processing and has higher mechanical properties than the as-cast state. It can be processed into various shapes and specifications of aluminum alloy.
Mainly used in the manufacture of aviation equipment, daily necessities, building doors and windows, etc. 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 have simple aluminum-silicon alloys (not heat-treated for strengthening, lower mechanical properties, casting Good performance), special aluminum-silicon alloy (heat treatment can be strengthened, high mechanical properties, good casting performance). Aluminum alloy telescopic ladder Behind the sub, adhere to a certain overlap interval.
The overlap interval of ladders under 8 meters should be at least 75 cm, and the overlap interval of ladders over 8 meters should be within More than 110 cm. Lift to a suitable height for use. After making sure that the lifting clip is stuck to the step, remove the fixed block at the bottom of the upper ladder and fasten the lifting rope. Open the ladder to a suitable width and use it. Please lift gently when lifting drop. The herringbone lift and the lifting channel should be operated by 2 people, 2 when liftingPeople pull the rope together and lift and descend together. The ladder over 6 meters should be assisted by at least 2 people to avoid the risk of the ladder falling to one side due to the uneven force at both ends of the center of gravity . There are two movable lifting fixing devices on both sides of the lowering channel. When moving, gather them. When lifting and working, please open the ladder to a suitable width and confirm it for fixing.
To standardize the use, inspection and maintenance of mobile climbing ladders and ladders (referred to as "climbing tools") This regulation is specially formulated to manage, prevent the occurrence of high-altitude work accidents, and protect the personal safety of employees and unit property. The person in charge of safety supervises the effectiveness of the implementation of this regulation by the unit, and reviews the inspection report on the implementation of this regulation.
