Technical Field

[0001] The utility model relates to the technical field of cable fixing brackets, in particular to a tower crane cable fixing bracket. Background Art

[0002] At present, when using tower cranes on construction sites, there are various ways to fix cables, and some are even fixed directly with wires. This not only poses a safety hazard to the use of tower cranes, but also easily causes cable damage and leakage accidents under the influence of external forces or its own weight.

[0003] There are many types of existing cable fixing brackets. Usually, a transition bracket is used with an insulating pad to clamp and fix the cable. However, the effect of this fixing bracket is relatively simple. When the cable needs to be bent according to the tower crane equipment, it is often difficult to bend the cable effectively and make the cable hang freely at the bend. This will cause the cable to be subjected to concentrated force, easily cause cable wear, and pose certain safety hazards. Utility Model Content
