Lifting chain can be convenient lifting weights, lifting the chain tension adjustment in the course also has a great knowledge of the chain adjustment too tight, will therefore greatly reduce the chain and sprocket life. When chain adjustment too tight, the contact pressure is increased because the tooth plate, easy to lengthen the chain, the link plate deformation or pull off the roller chain will therefore be broken. In addition, the gear plate will therefore make the tooth wear prematurely sharpened, serrated serious. More common chain adjustment too tight. Of which there are basically three reasons. (1) can not repair it yourself common sense adjustments, mistake chain tightening. This belongs to the ambiguous concept, only know how to adjust the chain is maintenance areas, I do not know how to adjust is the correct standard. (2) the tooth plate chain wear serious, but time does not permit, or economic, or shaped car was purchased locally less than the same type of tooth plate lifting chain spreader, put the chain back to tighten the Free maintain the vehicle is strong. (3) To replace the chain sprocket, mistakenly lost garden of tooth eccentric disc mounted on the motorcycle, causing the chain suddenly tight suddenly loose, check and adjustment, met loose end, the other end tight. No matter what reasons cause more than the adjustment too tight chain will therefore greatly reduce the chain and sprocket life. Buy adjusted too tight when the chain lifting chain, contact pressure is increased because the tooth plate, easy to lengthen the chain, the link plate deformation or pull off the roller chain will therefore be broken. In addition, the gear plate will therefore wear prematurely lifting chain standards sharpened teeth, severe serrated. 100 chain rigging made of special materials manufactured under the same intensity 25% higher than the diameter 80, and 120 chain strength higher than 100 by 25%. 1.100 is super-type chain rigging chain rigging, compared with 80 chain, super-type biggest advantage is in the same diameter, the rated load of up to 25%, that is at the same rated load, 100 Its diameter is smaller chain level. 2.100 chain rigging meet all the requirements of European standard EN818-4. 3.100 chain rigging surface has a higher hardness and better toughness. Chain links and attachments more wear. 4.100 chain rigging system can not be mistaken, because only chains and accessories have the same level in order to connect to each other. 5.100 chain rigging can break elongation least 20%. 6.100 chain rigging temperatures up to 200 degrees = 100% of the rated load of 200 degrees to 300 degrees = 90%, 300 degrees to 400 degrees = 75% of the 7,100 grade chain rigging by the DIN EN ISO 9001:. 2000 Quality performance management system to ensure the quality of the chain. In addition, by a third party inspection agency to conduct regular monitoring of production. 8.100 chain rigging are marked with the words "8E" by industry associations to give the highest level of official mark. Dalian lifting chain lifting chain _ _80 level lifting chain parameters from Hebei chen sling Manufacturing Limited. Dalian lifting chain lifting chain _ _80 level lifting chain parameters Hebei chen sling Manufacturing Co., Ltd.
