報(bào)廢依據(jù)

鋼絲繩是否安全根據(jù)下列條件確定：

 鋼絲斷裂的情況及數(shù)量；
 鋼絲靠近端部斷裂；
 鋼絲斷裂的集中程度；
 鋼絲斷裂的增加程度；
 股斷裂；
 由于鋼絲繩芯損壞，直徑減小；
 彈性降低；
 內(nèi)部和外部磨損；
 腐蝕；
 外形變化；
 因熱或電原因而造成的損壞

如果鋼絲繩的損壞是由于起重設(shè)備故障造成的，則在更換鋼絲繩之前，必須對設(shè)備起重實(shí)施修復(fù)。

06.1.15.1. 拆卸及裝配

1、 將吊具下落到地面或集裝箱上。
2、 拆下豎管的螺絲，打開旋鎖轉(zhuǎn)臂的鎖定裝置（1），然后拆下鎖定銷。
3、 將轉(zhuǎn)臂（2）轉(zhuǎn)動(dòng) 90°。
4、 將上架與吊具分開。
5、 松開兩個(gè) M8 螺絲，拆下旋鎖上部的楔子。
6、 松開螺母（3），拆下轉(zhuǎn)臂，旋鎖松開。

按照旋鎖檢查操作規(guī)程，檢查旋鎖狀況。

以相反的步驟安裝旋鎖。

Whether the rope is safe to use or not is determined by the following:
D
Nature and number of wire breaks
D
Wire breaks near terminals
D
Concentration of wire breaks
D
Build up degree of wire breaks
D
Strand brakes
D
Reduced diameter due to a damaged core
D
Decreased elasticity
D
Internal and external wear
D
Corrosion
D
Change in form
D
Damage caused by heat or electricity
If the damage in the rope is caused by failure in the lifting appliance, it must be repaired before
rope changing.

Disassembly and assembly
1. Lower top--lift on the ground or over container.
2. Open locking device (1) of twist--lock’s turning lever by removing screw from vertical pipe,
and then removing locking piston.
3. Turn the lever (2) 90_.
4. Headblock is then separated from top--lift spreader.
5. Remove wedge from the top of twist--lock by untightening both M8 screws.
6. Unscrew nut for catch (3). Turning lever can then be lifted off, and twist--lock is released.
Check the condition of twist--locks as explained in spreader twist--lock inspection
instructions.
Assembly of twist--lock is done in a reversed manner
