Construction machine

Abstract

Provided is a construction machine having a plurality of equipment units and a structural body supporting the equipment units, restricting height of each of the equipment units supported by the structural body with no considerable decrease in the strength of the structural body and no considerable restriction on the height dimension of the equipment units. The construction machine includes a structural body having a plurality of beam members, a first equipment unit placed on the structural body, and a second equipment unit which is other than the first equipment unit and placed on the structural body. The plurality of beam members includes a first beam member having a first placement surface on which the first equipment unit is placed and a second beam member having a second placement surface on which the second equipment unit is placed, the second placement surface being lower than the first placement surface. According to the invention, the heights of the above equipment units supported on the structural body can be suppressed without greatly reducing the strength of the structural body or substantial limitation to the height of the above equipment units.

Description

technical field [0001] The present invention relates to a construction machine such as a hybrid excavator, and more particularly to a construction machine including a plurality of devices and a structure supporting the plurality of devices. Background technique [0002] Conventionally, there is known a construction machine including a plurality of equipment and a structure supporting the equipment. For example, Japanese Patent Laid-Open Publication No. 2013-28915 (Patent Document 1) discloses an excavator including an upper frame constituting an upper revolving body as the structure. [0003] The above-mentioned upper frame includes: a middle part having a pair of left and right vertical plates; The front part of the above-mentioned right side platform has a pair of beams before and after. Each beam extends in the left-right direction. On the beams there is equipment spanning the beams. [0004] However, installation of equipment on beams in this way causes a problem in ...

AI Technical Summary

Problems solved by technology

Therefore, the height dimension of the device is limited

On the contrary, if the upper frame is designed so that the installation surface of the equipment is lowered in order to ensure the height dimension, the strength of the above-mentioned side platform may be reduced, or the layout of other equipment may be affected.
