2015-11-28
In general mechanical and electrical engineering,the use of wire rope electric winch is more frequency.So when we using this wire rope electric winch,we also need make appropriate choice for steel wire rope,this is because steel wire rope is the important guide tool when wire rope electric winch to pulling or lifting heavy material in a fixed position .
When choosing steel wire rope for wire rope electric winch
1,Generally speaking,the steel wire rope is composed by the high carbon steel wire rope twist around.As usual,the limit strength of steel wire rope is 1400MPa,1550MPa,1700MPa,1850MPa,2000MPa,and so on.
2,There are many different of specification for steel wire rope,in lifting contraction usual is 6x19+1,6x37+1,6x61+1 three types.
3,In lifting contraction,if the steel wire rope as cable rope,its safety factor should not less than 3.5;if as running rope,safety factor can’t less 5;as sling,its 8;if lifting people,its safety factor is not less than 10-12.
4,At last,if steel wire rope with abrasion,corrosion and broken wire(as long as one wire),it should be stop using and replaced immediately.
