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)为一个悬挂位，每一单元根据悬挂一个或多个电缆挂钩。 (1) the suitable cable hooks are selected according to the size of the cable and the size of the outer diameter. Each 1.2m to 1.8m (also can be limited by the cable is not limited) as a suspension position, each unit is hanged by one or more cables. （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, the special bolts or other hangers are perforated and the hook is fixed on the shaft wall. When the hook is fixed, the arc hook is vertical and pendulous. If a plurality of cables are hung, a group of hooks and 22 series suspension should be used. The construction personnel first connect the hook 22 in the ground and then fix in front. （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，两挂钩的直杆段成直角，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℃。一挂钩的保险扣刚好嵌入另一挂钩凹。 (3) when the two hooks are connected in series, the hanging hole of a hook is first aligned with the hanging rod of another hook. The straight bar section of the two hook is made into a right angle, and the hanging rod is fully entered into the hanging hole, and then the curved hook is rotated with the hook of the two hook to be 180 centigrade. The hook of the hook is inserted into another hook concave. （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) confirm that after the cable enters the arc hook as a whole, the construction personnel can 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 per unit can not be 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, it is best to close the shaft when it is stationary. If not, the series number should be reduced or the unit group should be reduced. （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 forbidden to send the cable quickly into the arc hook by the way of leaping in the air. It may cause the arc hook to withstand the weight of the human body in a moment and cause the fracture. （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) confirm that after the cable enters the arc hook as a whole, the construction personnel can release the cable.
