卷扬机安全操作须知 | 2011-2-10 8:36:00
一、作业前准备
1、安装时,基座必须平稳牢固,设置可靠的地锚并应搭设工作棚。操作人员的位置应能看清指挥人员和拖动或起吊的物体。
2、作业前检查卷杨机与地面固定情况,防护措施,电气线路,接地线,制动装置和钢丝绳等全部合格后方可使用。
3、使用皮带和开式齿轮传动的部分,均须设防护罩,导向滑轮不得用开口拉板式滑轮。
4、以动力正反转的卷扬机,卷筒旋转方向应和操纵开关上指示的方向一致。
5、从卷筒中心线到第一个导向滑轮的距离,带槽卷筒应大于卷筒宽度的15倍,无槽卷筒应大于20倍,当钢丝绳在卷筒中间位置时,滑轮的位置应与卷筒轴心垂直。
6、卷扬机自动操纵杆的行程范围内不得有障碍物。
二、作业中注意事项
1、卷筒上的钢丝绳应排列整齐,如发现重叠和斜绕时,应停机重新排列。严禁在转动中用手、脚拉踩钢丝绳。钢丝绳不许放完,最少应保留三圈。
2、钢丝绳不许打结、扭绕,在一个节距内断线超过10%时,应予更换。
3、作业中,任何人不得跨越钢丝绳,物体(物件)提升后,操作人员不得离开卷扬机。休息时物件或吊笼应降至地面。
4、作业中,司机、信号要同吊起物保持良好的能见度,司机与信号员应密切配合,服从信号统一指挥。
5、作业中如遇停电,应切断电源,将提升物降至地面。
三、作业完后注意事项
1、作业完毕,应断开电源,锁好开关箱。
2、提升吊笼或物件应降至地面,清整场地障碍物。
