Problems solved by technology

[0004] However, in the construction machine described in Patent Document 1, the real-time average fuel consumption rate is displayed on the display device together with the average fuel consumption rate for a certain period calculated every time it is reset, and the construction machine is not displayed. Cumulative fuel consumption rate since then
Therefore, although the latest fuel consumption rate information can be grasped, it may not be possible to judge whether the fuel consumption rate is good or bad by comparing the real-time average fuel consumption rate with the cumulative fuel consumption rate for the entire period

Embodiment Construction

[0019] Hereinafter, modes for implementing the invention will be described with reference to the drawings. In each drawing, the same reference numerals are assigned to the same components, and overlapping descriptions may be omitted.

[0020] figure 1 It is a side view of the excavator 100 of embodiment. On the undercarriage 1 of the excavator 100 that performs a traveling operation, a revolving upper body 3 is rotatably mounted via a revolving mechanism 2 . A boom 4 is attached to the upper revolving body 3 . Furthermore, an arm 5 is attached to the tip of the boom 4 , and a bucket 6 is attached to the tip of the arm 5 . Boom 4 , arm 5 , and bucket 6 constitute attachments, and are hydraulically driven by boom cylinder 7 , arm cylinder 8 , and bucket cylinder 9 . A driver's cabin (cockpit) 10 is provided on the upper revolving structure 3 , and a power source such as an engine as an internal combustion engine is mounted thereon. A driver's seat is provided in the driver'...

Abstract

The present invention provides building machinery, which is used for switching displaying grand average specific fuel consumption and section average specific fuel consumption in a display device. The building machinery comprises: a lower portion walking body configured to perform walking movement; an upper portion solid of revolution configured to carry the lower portion walking body with rotation freely; a cab configured to carry the upper portion solid of revolution; a specific fuel consumption calculating device configured to calculate the specific fuel consumption based on the duration of runs and the consumption of fuel; and a display device configured to carry the cab and capable of switching displaying at least one of the grand average specific fuel consumption and the section average specific fuel consumption.

Description

technical field [0001] The invention relates to a construction machine. Background technique [0002] Energy saving for the purpose of environmental protection has been promoted in various industrial fields. For example, in the field of construction machines, fuel consumption is emphasized for energy saving, and a construction machine in which fuel consumption information is displayed on a display device mounted on a driver's seat has been proposed (for example, refer to Patent Document 1). According to such a construction machine, the operator is made aware of the fuel consumption rate, and the operator is urged to suppress the fuel consumption during the work as much as possible, whereby energy saving can be achieved. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2013-76318 [0004] However, in the construction machine described in Patent Document 1, the real-time average fuel consumption rate is displayed on the display device together with the average fuel ...
