Traveling body for construction machine

Travelling body for construction machine

Provided is a construction machine including an electrical component and efficiently cooling it. The construction machine includes an upper slewing body having an air intake chamber capable of taking in air, an engine, the electrical component, an air intake duct guiding the air inside the air intake chamber toward the engine, a blow fan directing the air inside the air intake chamber toward the engine through the air intake duct, and electrical-component cover covering the electrical component. The electrical-component cover defines an air flow path for flowing air along the electrical component, between the electrical-component cover and the electrical component thereinside. The electrical-component cover includes an air inlet communicating an upstream portion of the air flow path with the air intake chamber and an air outlet communicating a downstream portion of the air intake chamber with the air intake duct.

Handrail mounts are provided in a bottom portion of a cast upper frame, and lower ends of side supports of a handrail are attached to the above handrail mounts. A base plate for attaching a floor plate is hanged and fixed between the side supports at a higher position than the attachment position, and a front end part of the floor plate is attached to the above base plate.

A working machine is constituted so as to mount a guard cover hinge, a radiator duct, a canopy right support, a hood catch and the right end part of a seat stand on a radiator support. The working machine further comprises a mounting column provided on the opposite side of the radiator support so as to mount a hood hinge, a left side panel, the left end part of the seat stand and a muffler cover thereon. According to such a structure, a mounting member shared by a plurality of constituting members can be used also as a positioning support between members, and the workability in assembling can be improved.
