The corporation mainly concentrates on producing different constructions of ungalvanized & galvanized steel wire rope, point contact, line contact, and surface contact wire rope, plastic-coated wire rope, phosphatized and galvanized wire, sling, and other metal products.
WE FOCUS ON PRODUCING WIRE ROPE AND METAL PRODUCTS
Jiangsu Zhongying Wire Rope Group Co.,Ltd was established in 2003, which specializes in producing wire rope and metal products. The Group has three factories and one import & export department (Power Machinery). Coving an area of 210000 square meters, the company has over 500 employees, boasting an annual output beyond 50000 tons. Rich experience and sufficient assets make the group more competitive among other counterparts.
During the last 20 years, Zhongying Steel Cable has always focused on the research and production of high-performance wire rope. The quality is the first mission of Zhongying. Every metal product is made by heart.
Opening of strand in rotation resistant,low rotation and parallel closed ropes-in extreme circumstances the rope may develop a “birdcage distortion” or protrusion of inner strands.
Note-rotation resistant and low rotation ropes are designed with a specific strand gap which may be apparent on delivery in an off tension condition.These gaps will close under load and will have no effect on operational performance of the rope.
>check sheave and drum groove radii using sheave gauge to ensure that they are no smaller than nominal rope radius +5% ZhongYing recommends that the sheave and drum groove radii are checked prior to any rope installation.
>Repair or replace drum/sheaves if necessary.
>Check fleet angles in the reeving system-a fleet angle in excess of 1.5 degrees may cause distortion.
>Check installation method-turn induced during installation can cause excessive rope rotation resulting in distortion.
>Check if the rope has been cut “on site” prior to installation or cut to remove a damaged portion from the end of the rope.If so,was the correct cutting procedure used?Incorrect cutting of rotation resistant,low rotation and parallel closed rope can cause distortion in operation.
Broken wires or crushed or flattened rope on lower layers at crossover points in multi-layer coiling situations. Wire breaks usually resulting from crushing or abrasion. Cause/Action >Check tension on underlying layers.ZhongYing recommends an installation tension of between 2% and 10% of the minimum breaking force of the wire rope,Care should be taken to ensure that tension is retained in service,Insufficient tension will result in these lower layers being more prone to crushing damage. >Review wire rope construction.ZhongYing wire ropes are more resistant to crushing on underlying layers than conventional rope constructions. >Do not use more rope than necessary. >Check drum diameter.Insufficient bending ratio increases tread pressure.
