The present invention adopts following structure as the means that are used for solving above-mentioned problem.Namely, such as technical scheme 1 described invention, it is characterized in that, in the construction machinery, at the base plate configuration effort oil tank of the top of construction machinery revolving body, and to carrying out pipe arrangement for suction pipe from this service tank to hydraulic pumping unit that supply with working oil from, make the tube connector that send hydraulic fluid port of this service tank towards oblique upper, and the pipeline of the suction pipe along the oblique upper pipe arrangement to this hydraulic pump, the space of having guaranteed to arrange at the downside of this suction pipe the strengthening part of strengthening base plate strength.
Technical scheme 2 described inventions is characterized in that in technical scheme 1 described invention, the working oil intake of described hydraulic pumping unit side is arranged at the downside of this hydraulic pumping unit and makes the suction side pipeline of pipeline of suction pipe vertical.
Technical scheme 3 described inventions is characterized in that in technical scheme 1 or 2 described inventions, and the strengthening part of base plate is strengthened by parts or the universal component identical with the part of the fixed part of described service tank.
Technical scheme 4 described inventions is characterized in that in technical scheme 1 to 3 described invention, and the strengthening part of described base plate is equipped on described service tank and is arranged at position between the pump installation manhole of base plate of pump installation below.
The invention effect:
In technical scheme 1 described invention, owing to can guarantee the space at the upper space of base plate, therefore can obtain strengthening part is set and the effect that can carry out to base plate the reinforcement and so on of effectual property.In addition, can obtain to shorten the effect of suction pipe pipeline and so on.In technical scheme 2, can also obtain further to shorten the effect of suction pipe pipeline and so on.In technical scheme 3, owing to make the part of fixed part general with strengthening part or identical, therefore can obtain to seek the effect of effective utilization and so on of fixed part.
