Mobile platform ladder, fasteners are used to connect between parallel or oblique rods. Scissors diagonal rods should be fixed with fasteners On the extended ends or vertical poles of the intersecting horizontal horizontal rods, the distance from the center line of the fastener to the main node should not be greater than 150mm. Both ends of the in-line and open-type double-row scaffolding must be provided with horizontal diagonal bracing, and the middle should be set at intervals. Set one in 6 spans. The longitudinal lap length is not less than 1 meter, and 3 fasteners are installed at equal intervals. The distance from the edge of the end fastener cover plate to the lap longitudinal horizontal rod end is not less than 100mm.
In recent years, with the rise of high-risk industries such as electricity and communications that need to face high-voltage power, Safety ladders have higher and higher requirements for their insulation function. The domestic sales of Shenshi also shows the enhancement of domestic enterprises' awareness of safe production and the ubiquitous deepening of the "people-oriented" concept. The material is made of high-strength aluminum alloy, which has the characteristics of high strength, good toughness and more durability. The interface is fully welded, which has the advantages of stable structure and not easy to loosen. The product has the characteristics of light weight, good load, and convenient use. Non-standard can be customized.
Mobile platform ladders. At present, there are more than 1,000 kinds of aluminum alloys officially registered in the world, and 450 kinds of commonly used ones are included in the 1xxx to 9xxx series, which is the world Economic development and the progress of human civilization have made great contributions. However, with the advancement of science and technology, the modernization of the national economy and the national defense industry and the improvement of people's living standards, some alloys have been eliminated, and there is an urgent need to develop a batch of high strength, high toughness, high modulus, low expansion and contraction, wear resistance, and corrosion resistance. , Fatigue resistance, high temperature resistance, low temperature resistance, radiation resistance, fire resistance, explosion-proof, easy cutting, easy polishing, surface treatment, weldable and ultra-light new alloy.
For example, 6b≥750MPa high-strength and high-toughness alloy, aluminum-lithium alloy with density less than 2.4 , Powder metallurgy and composite materials, etc. The working principle of the hydraulic system of the hydraulic lift freight elevator: when the hydraulic lift freight elevator rises, the electric control system controls the rotation of the motor to drive the gear oil pump to rotate, and the hydraulic oil is blocked by the oil filter and one-way under the action of the oil pump The valve and electromagnetic reversing valve enter the oil cylinder and drive the piston rod of the oil cylinder to move upward. The piston rod is driven by the external transmission mechanism to drive the elevator elevator up. If you use it frequently and require high load and stability, then buy folding Ladder. If you use it occasionally. If you need convenient storage, then choose a telescopic ladder.
Mobile Platform ladders, fishing rod type telescopic ladders are popular in the market now. Like bamboo joints, they have certain limitations in strength. If a single section is damaged, the entire ladder is useless. On the contrary, the slight damage to the folding ladder does not delay the use of the ladder. The mobile platform ladder is a kind of steel grating used for the platform stairs. According to the installation method, it is generally divided into two types: welding and screw fixing. It is directly welded to the side of the keel that does not require stepping. The board is relatively economical and durable, but it does not need to be dismantled. The bolted treads need thicker side boards on both sides, and the side boards are drilled. The installation is directly fixed by bolts and can be recycled and reused. Actually it needs to be customized and can be used for any type of steel grating to be manufactured into various sizes to match the corresponding stairs.
