Abstract

According to a preferred embodiment of the present invention, a construction machine cab having a rollover protection structure includes: a front right column disposed at the front right side thereof, and extending upward from the bottom frame; a front left column disposed at the front left side thereof, and spaced apart from the front right column; a front upper vertical column connecting the upper end of the front right column to the upper end of the front left column; a first reinforcement installed on the upper portion of the front right column; and a second reinforcement installed on the lower portion of the front left column.

Description

technical field [0001] The invention relates to a cab with a rollover protection structure for a construction machine. More particularly, the present invention relates to a cab with a rollover protective structure for a construction machine, which enables an operator to secure a sufficient front view by effectively disposing a reinforcement member at low manufacturing cost. Background technique [0002] Construction machines, such as excavators, have been used to perform work on civil engineering work sites to perform digging of earth, as well as sand or gravel. [0003] In general, such an excavator includes, as important components, a lower drive structure, an upper swing structure mounted to swing on the lower drive structure, and a cab for an operator fixedly provided on the upper swing structure. [0004] Such as figure 1 As shown, the prior art cab is configured to include a bottom frame, a front post positioned at the front to extend upwardly from the bottom frame, ...
