A work machine includes an engine, a motor-generator, a battery, a power detector, a temperature detector, and circuitry. The engine is to move the work machine. The motor-generator is to move the work machine and to generate electric power. The battery is to store the electric power generated by the motor-generator. The power detector is to detect a charge level of the electric power stored in the battery. The temperature detector is to detect a temperature of the battery. The circuitry is configured to control the motor-generator in accordance with the charge level selectively to move the work machine or to generate electric power when the temperature of the battery detected by the temperature detector is within a temperature range.

Work machine and method for controlling work machine

A cabin includes: a panel disposed on a side of an operator seat, the panel including: a plurality of cross members extending in a first direction; and a plurality of transverse members intersecting with the plurality of cross members each other and extending in a second direction; a glass panel disposed on a side of the panel; a window frame disposed on the glass panel; a window panel disposed on the window frame, the window panel being configured to move in the first direction or in the second direction; a projecting member disposed on a side of the window panel, the side being an identical side to the operator seat, the projecting member being configured to move together with the window panel; and a guide portion configured to accept insertion of the projecting member and to limit a moving distance of the window panel.

A working machine includes a travel device, a motive power transmission device configured to transmit a motive power to the travel device, a transmission case configured to house the motive power transmission device, and a hydraulic operation fluid tank disposed on an upper surface of the transmission case.

Working machine

A work machine includes a machine body, an engine, a rotary electrical device, and an electric power controller. The engine is provided on the machine body to move the machine body. The rotary electrical device is provided on the machine body to move the machine body. The electric power controller is disposed above the rotary electrical device in a height direction along a height of the work machine to control the rotary electrical device.

Work machine

A work machine includes a machine body, an engine, a rotary electrical device, and a battery. The engine is provided on the machine body to move the machine body. The rotary electrical device is provided on the machine body to move the machine body and to generate electric power. The battery is to be charged by the rotary electrical device and to discharge electric power to the rotary electrical device to move the machine body. The battery being is provided adjacent to the engine.

A displacement switch includes a main operation portion having a hollow shape. The main operation portion includes a top surface via which the displacement switch is operated, and a side surface connected to the top surface to define the hollow shape. The displacement switch also includes a support member connected to the main operation portion and swingable around a swing axis together with the main operation portion, and a base including a peripheral wall surrounding an insertion inlet into which the support member is inserted. The main operation portion covers the insertion inlet such that the side surface surrounds an outer peripheral surface of the peripheral wall.
