Traveling body for construction machine

Travelling body for construction machine

Provided is a construction machine in which the weight of a top plate of an aftertreatment device mount is reduced without reducing the rigidity of the top plate. In a construction machine where a vehicle body frame for mounting an engine is equipped with an aftertreatment device mount for supporting an exhaust gas aftertreatment device, a mount top plate of the aftertreatment device mount includes a support on which the exhaust gas aftertreatment device is placed, a pair of outer walls extending parallel, a groove portion parallel to the outer walls, a connecting portion provided on the support, and an upper reinforcing member orthogonal to the groove portion at a position of the connecting portion. The upper reinforcing member includes a first reinforcing portion for reinforcing the connecting portion and a second reinforcing portion to be fitted in the groove portion.

Power shovel

Provided is a construction machine having a central foothold and a maintenance access passage with high safety. The construction machine includes an upper slewing body including: an upper frame, an engine compartment, a cabin on a right or left region of the upper frame, a central foothold immediately forward of the engine compartment and on a central region of the upper frame widthwise of the upper frame, and a maintenance access passage extending rearward while elevated to guide a worker from the ground forward of the upper frame to the central foothold on a side opposite to the cabin. Widthwise of the upper frame, an inward edge of an upper end portion of the maintenance access passage is located inward of one edge of the central foothold, to thereby form a transit zone between the maintenance access passage and the central foothold.

Counterweight for construction machine

A working machine has a machine room cover and a bonnet on an upper rotating body. The bonnet has a frame-like raising member and a dome-like hood member that covers an opening in the upper part of the raising member. The lower part of the raising member is attached so as to surround an opening portion formed in the upper surface of the machine room cover, and the hood member is attached to the raising member so as to be able to be rotationally opened and closed.
