井字架是中小型施工单位不可缺少的垂直运输工具,应用十分普遍,但也存在一定的安全隐患。例如钢丝绳拖地,影响了人车通行,钢丝绳易损,影响使用寿命及整机完好率。尽管可以采取插地辊筒等措施,但实际应用仍不尽人意。对此,我们进行了反复探讨和实践,改变了传统的井架与卷扬机分离安装的 Tic Tac is an indispensable vertical transportation tool for small and medium sized construction units. The application is very common, but there are also certain security risks. For example, the dragging of steel wire ropes affects the traffic of people and vehicles, and the wire ropes are easily damaged, affecting the service life and the integrity rate of the whole machine. Although it is possible to take measures such as inserting rollers, practical applications are still not satisfactory. In this regard, we have repeatedly discussed and practiced and changed the traditional derrick and winch separation and installation.
