High-strength chain tied rigging, rigging tied one limb, two limbs tied rigging rigging high-strength chain metal chain link connection is made rigging, their main form of welding and assembling two kinds, according to their structure divided into single-and multi-limb limbs, etc., made of high quality alloy steel, it features a wear-resistant, high temperature resistance, corrosion resistance, low ductility, the force will not stretch like. Its long life, easy to bend, suitable for large-scale, frequent use of the occasion. Flexible multi-limbed, a variety of combinations can improve efficiency and reduce costs. Chains and chain rigging using methods and precautions; 1. Chains and chain rigging before use, must read and sign the work load on the scope of use of non-overloading, and chain rigging to do visual inspection, in line before be used. 2 Under normal conditions of use, lifting the key point is the impact load, maximum lifting angle must not exceed 120 °, otherwise it will cause chain rigging local overload. 3 prohibits direct bearing chain rigging hanging on a hook on the crane hook or wrapped around the hook 4. Between the chain and prohibiting the use of non-formal connections connections. 5. Chain rigging was hanging around when things need padded edges and corners to prevent ring chain and hanging objects damaged. 6 of temperature on the use of chain rigging has some influence in the following table 1. Temperature 1. Due to higher temperatures reduce the load of the new post-quota set 1. -40 ℃ -200 ℃ 1. 100% of rated load of the original one. 200 ℃ -300 ℃ 1. primary rated load 90% 1. 300 ℃ -400 ℃ 1. primary rated load 75% 1. 400 ℃ above 1. allowed 1 crane hook crane lifting point requirements heavy heart in the same vertical line, so that lifting in a stable state of equilibrium, when promoted to prevent slippage or tipping. 2 link between the ban reversed, twisted, knotted, adjacent chain link activities should be flexible. 3 noon lifting up, down, stop to slow and steady, the focus of attention was hanging objects balance, to avoid shock loads shall not place heavy objects hanging in long hanging chain. 4 spreader is not suitable for hooks, hanging ears, eye bolts and other connectors, a single limb and multiple limb chain rigging can adopt bundled knot cable method, if the lifting loose categories of articles (such as pipes, wood, etc.), can be surrounded by chain more around heavy weights around approach. 5. Chain rigging to gently, non-beat, throwing touch and drag on the ground, to prevent falls from a height to avoid hanging chain deformation, surface and internal damage. 6 chain rigging should do the cleaning after use and the corresponding detection, no exception should be placed on a dedicated stand, not on the ground, all spreader store to clean, dry oiled. Storage sites to be ventilated, dry, non-corrosive gases. 7 Do not attempt to forcibly pulled out from under the heavy chain rigging, or so that the weight on the chain rolling. Skid rigging / bundled rigging rigging Tianjin Yi Yun bundled rigging, high-strength chain, duplexes Drum Lifter is using the most advanced equipment and the most advanced manufacturing chain braking chain technology used internationally the highest quality alloy steel, with a range of: Φ6-Φ48, also according to customer demand production of different pitch chain. Chain rigging using finite element analysis and CAD-aided software, reference EN818-4, GB/T20652 standards such as making the production, rigging chain can be divided according to the number of cable limb single limb, two limbs and multiple limb. Its outstanding advantages are resistant, high temperature resistance, corrosion resistance, low ductility, the force will not stretch, mainly used in manufacturing, transportation, mining and other fields.
