Technical Field

[0001] The utility model relates to the technical field of electric power cross-arms, in particular to an electric power cross-arm installation device. Background Art

[0002] Power crossarms are essential components used to support and secure wires and cables in power systems, often found atop power towers or concrete poles. Primarily made of horizontally fixed angle steel, they work with insulators and electrical hardware to support conductors, lightning conductors, and other components, ensuring they maintain the required safe distances. Crossarms are made from a variety of materials, including iron, wood, and ceramic. Iron crossarms are the most common, typically made from equal-legged angle steel.

[0003] When there is no condition to use lifting equipment to install the crossarm in the field, the power workers are required to climb up the power pole to install the crossarm. However, the crossarm is heavy, and it is difficult for the workers to carry the power crossarm when climbing on the cement pole. This is not only dangerous but also inefficient. Therefore, a power crossarm installation device is now proposed. Utility Model Content
