摘要

A leveling apparatus for excavator and forestry machine equipment is provided. The leveling apparatus is mounted between an upper swing structure and a lower frame formed on a lower driving structure including a swing bearing, left and right track chassis, and a front arm and a rear arm connected to upper parts of the track chassis, to keep a horizontal level of the upper swing structure against an inclined ground. The leveling apparatus includes a swing bearing mounting plate mounted on a lower part of the swing bearing and including a pair of pivot support parts and a pair of second piston holders; a support plate fixedly installed on an upper part of the lower frame and having a pair of pivot support parts; a tilt plate mounted between the swing bearing mounting plate and the support plate to be tilted, and including a pair of first pivot holders, a pair of second pivot holders, a first shaft; and a second shaft; and a pair of first actuators and a pair of second actuators; wherein the tilt plate includes a vertical center line crossing a center line in a length direction of the lower frame, and the respective actuators are installed to be radially apart from the vertical center line.
