起重机钢丝绳检查怎么做?
一、日常检查
Daily inspection
至少应在特定的日期对预期的钢丝绳工作区段进行外观检查,目的是发现一般的劣化现象或机械损伤。此项检查还应包括钢丝绳与起重机的连接部位。
At least the expected steel wire rope working section should be inspected at a specific date to find general deterioration or mechanical damage. The inspection shall also include the connection between the steel wire rope and the crane.
对钢丝绳在卷筒和滑轮上的正确位置也宜检查确认,确保钢丝绳没有脱离正常的工作位置。
Check the correct position of the wire rope on the drum and pulley and ensure that the wire rope is not out of the normal working position.
所有观察到的状态变化都应报告,并且由主管人员根据定期检查的规定对钢丝绳进行进一步检查。
All observed state changes shall be reported and shall be further examined by the competent personnel on the basis of regular inspection.
无论何时,只要索具安装发生变动,如当起重机转移作业现场及重新安装索具后,都应按本条的规定对钢丝绳进行外观检查。
Whenever the rigging of the rigging is changed, such as when the crane transfers the job site and the reinstallation of the rigging, the steel wire rope shall be inspected according to the provisions of this article.
二、定期检查
Check regularly
1、总则
1, general
定期检查应由主管人员实施。从定期检查中获得的信息用来帮助对起重机钢丝绳做出如下判定:是否能够继续安全使用到最近的下一次定期检查;是否需要立即更换或者在规定的时间段内更换。
Regular inspections shall be carried out by the supervisors. The information obtained from the regular inspection is used to help the crane wire rope to determine whether it can continue to safely use the next regular inspection. Whether it is necessary to replace immediately or within the prescribed time period.
2、检查周期
2. Inspection cycle
定期检查的周期应由主管人员决定,并且至少应考虑如下内容:国家关于钢丝绳应用的法规要求;起重机的类型及工作现场的环境状况;机构的工作级别;前期的检查结果;在检查同类起重机钢丝绳过程中获取的经验;钢丝绳已使用的时间;使用频率。
The periodic inspection cycle should be determined by the supervisor and should be considered at least as follows: national regulatory requirements on the application of the wire rope; Type of crane and the condition of work scene; The level of work of the organization; Preliminary examination results; The experience gained during the inspection of the similar crane wire rope; Time of use of wire rope; Use frequency.
3、检查范围
3. Scope of inspection
对每根钢丝绳,都应沿整个长度进行检查。
Each wire rope should be inspected along the length.
对超长的钢丝绳,经主管人员同意,可以对工作长度加上卷筒上至少5圈的钢丝绳进行检查。
For super-long wire rope, the supervisor agrees to check the length of work and wire rope at least 5 laps in the drum.
应特别注意下列关键区域和部位:卷筒上的钢丝绳固定点;钢丝绳绳端固定装置上及附近的区段;经过一个或多个滑轮的区段;经过安全载荷指示器滑轮的区段;经过吊钩滑轮组的区段等等。
Special attention should be paid to the following key areas and sites: the steel wire rope fixation points on the drum; The rope end fixture and the surrounding section; An extent of one or more pulleys; The section of the pulley of the safety load indicator pulley; Through the segments of the sling, and so on.
