AN ELECTRIC WIRE FIXTURE UTILIZING AN UPPER SWING FRAME OF HEAVE CONSTRUCTION EQUIPMENT

摘要

PURPOSE: A device for fixing a rotary frame wire for a construction machine is provided to easily maintain an electric wire in a wire through hole inside a winding unit by directly attaching a wire support to one side of a rotary frame. CONSTITUTION: A rotary frame includes a plurality of reinforcement ribs. A boom support plate includes a boom support combined with a boom fixing pin for fixing the boom base unit. A winding unit(30) includes a wire support unit(31) fixed on the rotary frame and a first guide(32) which supports one side of the electric wire separated from the wire support unit. A wire through hole with a hole inlet(33) is formed on the winding unit. A second guide(35) is protruded from the other side of the wire support unit and forms a wire fitting inlet(36) connected to the hole inlet along the longitudinal direction of the first guide.
