One of the operating procedures of steel wire rope electric gourds is "not allowed to crooked slice", but in the actual lifting process, the phenomenon of crooked stretching cranes due to the quality or objective conditions of the construction personnel is due to the limitation of the construction personnel. Limitation of quality or objective conditions causes the phenomenon of crooked sliding cranes. Once this happens, it is easy to cause damage to the wire rope electric gourd, and it will be scrapped by the wires and steel wire ropes, and the entire electric gourd is scrapped or personal damage, which will cause certain economic losses and seriously affect construction production. The crooked stretch of the wire rope electric gourd can be prevented. It can be designed with a anti -crooked sliding crane device. This device uses the steel wire rope when the crooked stretch is lifted to generate a certain partial diagonal angle to make the limited limit installed on the electric gourd. The bit switch work, so as to automatically disconnect the lift in the contact, limits the promotion function. This set of devices not only have anti -crooked sliding sliding cranes, but also have a high degree of limit function. After practical use, the effect is many, the reliability is also very high, and it can be placed on the crooked slice. In addition, if you want to prevent crooked stretching cranes in the use of steel rope electric gourds, you should start with use, strictly abide by the basic principles of "vertical lifting", strictly require operators to improve the professional level of operators.
