  • Patent number: 9366005
    Abstract: Provided is a sufficiently reinforced swing bracket of a construction machine. The swing bracket includes a bracket body, a main connection portion connected to an upper slewing body of the construction machine, a swing-cylinder connection portion being protruded from one of right and left side parts of a lower end region of the bracket body to be connected to an end part of the swing cylinder and having a pair of supporting arms vertically opposed to each other with an interval, and a reinforcement portion for reinforcing a basal part of the swing-cylinder connection portion. The reinforcement portion has a main rib briding the supporting arms, and upper, lower, front, and rear ribs each extending from the main rib to an opposite side from the swing-cylinder connection portion. The upper and lower ribs and the front and rear ribs are continuous to form a box-shaped body.
