Abstract

To provide an electric work machine that ensures sufficient installation space for equipment including batteries while maintaining good rearward visibility for the operator. [Solution] The vehicle is provided with a plurality of devices including a battery 63, a cab 22 with an opening 23 formed on its rear side 22B, and a mounting section 21B on which the plurality of devices are mounted. The mounting section is positioned behind the cab and extends to one side in the left-right direction from the cab. The plurality of devices include first devices 64, 65 and a second device 69 positioned below the first devices. The first and second devices are arranged such that the other end of the first device in the left-right direction is offset to one side relative to the other end of the second device.

Claims

1. An electric work machine having a work device driven by electricity, Multiple devices arranged in a vertical direction, A cab having a rear side with an opening formed therein, which forms the driver's compartment. It comprises a mounting section on which multiple of the aforementioned devices are placed, At least some of the multiple devices include a battery, The mounting portion is positioned behind the cab and has a shape that extends to one side in the left-right direction from the cab. The plurality of devices include a first device having an upper surface located above the lower edge of the opening, and a second device adjacent to the first device on its lower side. An electric work machine characterized in that the first device and the second device are arranged such that the other end of the first device in the left-right direction is offset to the one side relative to the other end of the second device.

2. In the electric work machine described in claim 1, The second device is an electric work machine characterized in that its left-right dimension is larger than that of the first device.

3. In the electric work machine described in claim 2, The device comprises three or more of the aforementioned devices, An electric work machine characterized in that, for two adjacent devices located vertically, the left-right dimension of the upper device is less than or equal to the left-right dimension of the lower device.

4. In the electric work machine described in claim 1, The second device is an electric work machine characterized in that it has an upper surface located above the lower edge of the window.

5. In the electric work machine according to claim 4, The electric work machine is characterized in that the second device is positioned so as to overlap with a part of the opening when viewed from the front.

6. In the electric work machine described in claim 1, The electric work machine is characterized in that the second device has an upper surface located at the same height as the lower edge of the opening or at a lower position than the lower edge of the opening.

7. In the electric work machine described in claim 1, The device comprises two or more of the aforementioned devices, An electric work machine characterized in that at least the first device and the second device are mounted on the mounting part described above such that the positions of their respective ends are the same.

8. In the electric work machine described in claim 1, A panel is provided above the mounting section and covers the entire device, The electric work machine is characterized in that the panel has a shape in which the upper end position is higher on one side in the left-right direction.

9. In the electric work machine described in claim 1, An electric work machine characterized in that the plurality of devices include overlapping devices positioned so that at least a portion of them overlaps with the rear side of the cab when viewed from the front, and the overlapping devices have a shape that creates a gap in the front-rear direction between the overlapping devices and the rear side of the cab.
