电缆挂钩安装及注意事项
Cable hook installation and precautions
安装说明
Installation instructions
1） 根据电缆型号及外径的大小选择适合的电缆挂钩，每1.2m～1.8m(也可以以电缆不下垂为限)为一个悬挂单位，每一单元根据悬挂一个或多个电缆挂钩。
1) Choose the suitable cable hook according to the cable type and the size of the outer diameter. Every 1.2m to 1.8m (which can also be limited to cable sag) is a suspension unit. Each unit hangs one or more cable hooks according to the suspension.
2） 悬挂时，先将专门螺栓或其它悬挂件穿孔将挂钩固定在井壁上，挂钩固定时，弧形钩呈垂直下垂状。如多根电缆悬挂需采用一组挂钩两两串联悬挂。施工人员在地面上先将挂钩两两串联，再依前法固定。
2) When hanging, special bolts or other hanging parts are pierced to fix the hook on the shaft wall. When the hook is fixed, the arc hook is vertical sagging. If multiple cable suspensions are used, a group of hooks and two series suspensions shall be adopted. On the ground, the construction personnel first connect two or two hooks in series, and then fix them according to the former method.
3） 两个挂钩串联时，先将一个挂钩的挂孔对准另一个挂钩的挂杆，用力按入，使挂杆完全进入挂孔，然后手持弧形钩旋转，使两挂钩直杆段成180℃。
3) When two hooks are connected in series, one hook's hanging hole is pointed at the other hook's hanging rod, and the hanging rod is pressed in forcefully, so that the hanging rod enters the hanging hole completely, and then the arc hook is rotated by hand to make the straight rod section of the two hooks 180 C.
4） 确认电缆整体进入弧形钩后，施工人员才可以放开电缆。
4) Only when the cable enters the arc hook as a whole can the constructor release the cable.
注意事项
Matters needing attention
1） 每一单元可串联挂钩个数不易超过10个。
1) The number of hooks in series for each unit is not more than 10.
2） 为提高悬挂质量，挂钩的直杆段在静止时最好紧靠井闭，如无法做到，应适当减少串联个数或增加单元组。
2) In order to improve the suspension quality, the straight rod section of the hook should be close to the well closure when it is still. If it is not possible to do so, the number of series connection should be reduced or the unit group should be increased appropriately.
3） 严禁施工人员以凌空跳跃方式将电缆快速送入弧形钩，可能使弧形钩在瞬间承受电缆加人体的重量，造成断裂。
3) It is strictly forbidden for the construction personnel to send the cable into the arc hook by jumping in the air, which may cause the arc hook to bear the weight of the cable and the human body in an instant and cause the cable to break.
4） 确认电缆整体进入弧形钩后，施工人员才可以放开电缆。
4) Only when the cable enters the arc hook as a whole can the constructor release the cable.
