Counterweight for a construction machine

A working machine includes a load transmitting member including: an upper pillar part; an intermediate part extending to circumvent a window from a position above a lower corner of a window edge of the window and outer than the lower corner in a wall width direction to a position below the lower corner and inner than the lower corner in the wall width direction; and a beam part extending so as to be farther away from a wall side edge under the window. The upper pillar part, the intermediate part, and the beam part are continuous in this order so that a load applied to an upper portion of a cabin is transmitted to an upper frame. At least the intermediate part of the load transmitting member is made of a single member.

Monitor cover for a construction machine

Provided is a compact and high-strength cab capable of securing an excellent field of view for work. The cab includes a guard protecting a cab body, and a wiper having a blade to wipe a front window member and a blade actuator for actuating the blade. The guard includes a pair of side pillars and an actuator housing beam interconnecting the side pillars and housing the blade actuator. The actuator housing beam includes a hollow beam body formed with a body opening and a front-rear partition plate partitioning the inside of the beam body into front and rear sections. The body opening allows the blade actuator to be assembled to the front-rear partition plate therethrough.

A floor member includes a floor plate extending in a length direction along a front-rear direction of a cab. The floor plate includes front-left corner portion, front-right corner portion, rear-left corner portion, and rear-right corner portion; a first vertical beam member; a second vertical beam member; and a plurality of support members which support the first vertical beam member, the second vertical beam member, and the floor plate in respective regions including a region where the front-left corner portion and a first front end overlap each other, a region where the rear-left corner portion and a first rear end overlap each other, a region where the front-right corner portion and a second front end overlap each other, and a region where the rear-right corner portion and a second rear end overlap each other.

Floor member and working machine

Provided is a working machine including a console box restrained from wobble. The working machine includes a machine body having an operator's seat and a console box at a side of the operator's seat. The console box includes a box body and a box cover covering the box body. The box cover internally includes a first cover half installed on the box body with first fitting portions and a second cover half internally including second fitting portions fitted with the respective first fitting portions. The second cover half abuts on the first cover half and coupled to the first cover half by respective interfittings of the first and second fitting portions. The box body includes a support portion making contact with an inner surface of the second cover half to support the second cover half.

A seat stand includes a seat support section including an installation plate portion having an upper surface on which a seat is provided and an left control box support section extending from a seat support section to the left side of the seat and supporting a left control box. The left control box support section includes an extension portion extending sideward from the installation plate portion and including an upper surface on which the left control box is supported. A arranging space is provided under the extension portion in such a manner that a connection line extending from the left control box supported on the extension portion is arranged through the arranging space. A cutout portion, formed in the extension portion, penetrates the extension portion in a vertical direction and is open sideward.

Seat stand and working machine including same

Provided is an upper slewing body comprising: an upper frame, a cab including a bottom frame, a plurality of pillars including an outer pillar, and an entrance; an antivibration mount; a displacement restrainer restraining a cab displacement in a direction of rising away from the upper frame; and a reinforcing member attached to a lower end of the outer pillar for reinforcing a joint between the lower end and the bottom frame. The displacement restrainer includes a penetrating member vertically penetrating the reinforcing member and the bottom frame and secured to the upper frame. The displacement restrainer and the reinforcing member includes respective load transmitting surfaces for transmitting a load to each other above the joint between the bottom frame and the outer pillar when the cab is displaced in the rising direction by a specific amount or more.

Upper slewing body for use in construction machine

Provided is a cab for construction machine, having an excellent operator protection effect against a lateral load. Provided is a cab disposed on an upper frame of a construction machine, including a pair of rear pillars and a rear panel disposed therebetween. The rear panel includes an outer panel and an inner panel including a plurality of panel portions vertically arranged and a bridge portion partly bridging the panel portions vertically adjacent to each other at a position offset from a lateral center position of the rear panel. The bridge portion forms a low-strength portion having lower strength than that of the panel portions so as to make the low-strength portion include a bending point at which the rear panel is bent when a lateral load acts thereon through an outer rear pillar.

Provided is a construction machine where a pilot hose is easily routed. The construction machine includes a seat stand, an operator's seat provided on the seat stand, a remote control valve provided just above a front end of the seat stand at least one of right and left sides of the operator's seat; a hydraulic valve; and a pilot hose interconnecting the remote control valve and the hydraulic valve. The seat stand has an upper surface including a specific surface located beneath the remote control valve and a reference surface on which the operator's seat is installed. A step is provided between the specific surface and the reference surface to make the specific surface be lower than the reference surface, thus enlarging a space for routing the pilot hose beneath the remote control valve.
