Abstract

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.

Claims

1. A working machine comprising:

a lower traveling body;

an upper rotating body rotatably mounted on said lower traveling body, the upper rotating body having an upper frame;

devices and an accessory mounted on said upper frame, said devices including an engine and a radiator;

covers for covering said devices and said accessory;

a mounting member for mounting two elements selected from a group consisting of said devices, said accessory and said covers thereon; and

positioning supports adapted to arrange said two elements in a predetermined position of the mounting member.

2. The working machine according to claim 1, wherein said covers and one of said devices and said accessory are mounted on said mounting member.

3. The working machine according to claim 1, wherein said covers includes an openable guard cover for covering said devices, said accessory is a radiator duct for guiding cooling air between said radiator and the guard cover, and said mounting member is a radiator mounting member for mounting said radiator, said mounting member being provided on one lateral side at a rear part of said upper frame, and wherein a guard cover hinge as one of the positioning supports adapted to assist positioning of said guard cover is attached on the radiator mounting member, and said radiator duct is detachably mounted on the radiator mounting member.

4. The working machine according to claim 3, the guard cover is openable around said guard cover hinge as fulcrum on its opening and closing.

5. The working machine according to claim 1, wherein one of said covers is an openable guard cover for covering said devices, and said accessory comprises canopy supports adapted to support a canopy for covering an operator'"'"'s seat from above, the canopy supports being arranged in the vicinity of said guard cover, wherein

said mounting member is a radiator mounting member for mounting said radiator, said mounting member being provided on one lateral side at the rear part of the upper frame, and wherein a guard cover hinge as one of the positioning supports adapted to assist positioning of the guard cover is attached on the radiator mounting member, and said canopy supports are mounted on the radiator mounting member.

6. The working machine according to claim 1, wherein said covers include an openable hood for covering the back side of said engine and a side panel arranged on one lateral side at the rear part of the hood adjacently to the hood, and wherein

said mounting member is a mounting column provided on one lateral side at the rear part of said upper frame, a hood hinge as one of said positioning supports adapted to assist positioning of said hood is attached on the mounting column, and said side panel is mounted on the mounting column.

7. The working machine according to claim 6, wherein said hood is openable around said hood hinge as fulcrum on its opening and closing.

8. The working machine according to claim 1, wherein said covers include an openable hood for covering the back side of said engine,

said accessory includes a muffler cover for covering a muffler for engine exhaust, said muffler cover being arranged in the vicinity of said hood, and wherein said mounting member is a mounting column provided on one lateral side at the rear part of said upper frame, a hood hinge as one of the positioning supports adapted to assist positioning of said hood is attached on the mounting column, and said muffler cover is mounted on the mounting column.

9. The working machine according to claim 1, wherein said mounting member includes both a radiator mounting member for mounting said radiator and a mounting column for mounting one of the covers, wherein said radiator mounting member being provided on one lateral side at the rear part of said upper frame and said mounting column being provided on the opposite side of the radiator mounting member, and wherein said positioning supports include a seat stand having an operator'"'"'s seat, said seat stand being on said upper frame, and said seat stand extends from said radiator mounting member to said mounting column in such a manner of constituting a mount base.

10. The working machine according to claim 9, wherein said covers include an openable hood for covering the back side of said engine, and

a hood hinge that serves as fulcrum on opening and closing said hood is attached to one of said radiator mounting member and said mounting column, and a hood catch for keeping said hood in a closed state is attached to the other, said hood hinge and said hood catch serving as said positioning supports.
