钢绳（链条）安全使用规程

吾爱

<p>　1. 吊物用的钢绳其允许载重量应比行车载重量略大或相等，吊物不准超过行车或钢绳的载重量。</p>
<p>　　2. 钢绳在使用前必须经过检查，如发现有火烧、过锈、扭结、压扁、严重弯曲、油层过厚、笼状畸变、绳径局部增大或减小，或钢绳套小于三个插花等，禁止使用，表面钢绳丝有直径磨损达40％或钢绳有一股拉断时应作报废处理。</p>
<p>　　3. 不许用钢绳吊炽热的钢坯和钢材。</p>
<p>　　4. 钢绳用完后要放在干燥地方，但不许放在高温处。</p>
<p>　　5. 钢绳接头长不应小于绳直径15倍，但最短不得小于300mm。</p>
<p>　　6. 钢绳吊物时，其两根绳之间的角度不得大于120度。</p>
<p>　　7. 各种规格的钢绳允许载重量如下：</p>
