A construction machine is capable of reducing a decrease in work efficiency due to maintenance for capturing dust. The construction machine includes: an engine; a heat exchanger; a cooling fan that sucks air into an engine chamber to pass the air through the heat exchanger; an intake chamber independent of the engine chamber; an intake tube connected to the intake chamber; and a dust receiving part. The intake tube has a curved part, which has an outside inner wall surface allowing dust in the air to contact it. The dust receiving part is located downstream of the outside inner wall surface to be capable of receiving dust.

An electric loader is provided with a plurality of independently driven wheels. For example, a four-wheeled electric loader includes four independently operated wheels, each directly coupled to a dedicated electric motor. A fifth independent electrical motor powers the lift arm and/or any attachments coupled to an auxiliary hydraulic. A central forced-air system supplies pressurized air to each independent electric motor to cool the electric motor during operation. In some embodiments, the auxiliary electric motor powers the fan and/or air conditioner of the central forced-air system. A lever and/or electric brake may be applied to an axle of the electric motors. In some embodiments, a rotating or pivotable battery panel locks a plurality of battery cells to provide a central source of power, counter-weight the loader arm, and rotate away to provide the operator access to an internal cavity of the cab.

A work vehicle includes a vehicle body frame including a first inner frame including a first connection and a first inner projection projecting above the first connection in a height direction, a first outer frame including a second connection and a first outer projection projecting above the second connection in the height direction, and a first connection frame having a first opening and connected to the first connection and the second connection between the first inner frame and the first outer frame. A first arm hydraulic cylinder is provided to pass through the first opening. The first cover is configured to surround an outer periphery of the first arm hydraulic cylinder to cover the first opening and provided on the first connection frame to be slidably guided by the first connection frame, the first inner projection, and the first outer projection.

A storage assembly for switches couplable to batteries of an electric machine to energize the batteries. The storage assembly includes a container defining a cavity to store the switches, a lid movable between a closed state and an open state with respect to the container to respectively close and open the cavity, and a lock out tag out (LOTO) device. The container is configured to be grasped between a pair of arms of a handrail that swings with respect to a walkway platform of a power compartment of the electric machine. The LOTO device is interchangeable with the switches to selectively be received in the cavity in place of the switches when the switches are coupled to the batteries, and be coupled to the batteries in place of the switches to lock out and keep the batteries from energizing when the switches are received in the cavity.

A working machine includes a support bracket attached to a machine body, a first mounting member provided to the support bracket and formed of an elastic member, a first cooler and a second cooler arranged in parallel to a horizontal direction and mounted on the support bracket with the first mounting member, a fitting bracket detachably fitted to upper portions of the first and second coolers, and a second mounting member arranged between the fitting bracket and the first and second coolers and formed of elastic member.

A floor mat arranged in a working machine includes a floor portion, a wall portion arranged on a circumferential portion of the floor portion, and an opening portion arranged on a part of a connecting portion of the wall portion, the connecting portion connecting to the floor portion. The floor mat includes a mat main body arranged on the floor portion, a covering portion configured to cover the opening portion, and an connecting portion configured to connect the covering portion flexibly to a circumferential portion of the mat main body.

A working machine includes: a machine body; a frame member; a cover member; and a hinge with which the cover member is swingably supported on the frame member, a connector plate attached to the hinge, the hinge includes: a movable arm which is supported on the frame member such that the movable arm is swingable up and down; a mounting plate which is fixed on a swinging end of the movable arm; the mounting plate has a hole for insertion of a mounting bolt, the hole being an elongated hole including: a mounting area through which the mounting bolt is passed to attach the connector plate to the mounting plate; and a guiding area which extends from the mounting area to guide the mounting bolt therethrough, and the guiding area extends upward from the mounting area when the movable arm is in an upward swung position.

The construction machine includes: an engine; a heat exchanger; a cooling fan that sucks air into an engine chamber to pass the air through the heat exchanger; an intake chamber independent of the engine chamber; an intake tube connected to the intake chamber; and a dust receiving part. The intake tube has a curved part, which has an outside inner wall surface allowing dust in the air to contact it. The dust receiving part is located downstream of the outside inner wall surface to be capable of receiving dust.

A work vehicle includes a vehicle body frame, an engine hood, a first extendable member, and a second extendable member. The vehicle body frame is configured to support an engine. The engine hood has a cover frame coupled to the vehicle body frame so as to allow opening and closing, and an engine cover attached to the cover frame. The first extendable member is coupled to the vehicle body frame and the cover frame. The first extendable member is disposed at one end side relative to a center in a vehicle width direction of the work vehicle. The second extendable member is coupled to the vehicle body frame and the cover frame. The second extendable member is disposed at an other end side relative to the center in the vehicle width direction of the work vehicle.

A cover mounting bracket (16) is provided on an upper side of a left weight part (11) and a right weight part (12) constituting a counterweight (10). The cover mounting bracket (16) is formed as a U-shaped frame with the counterweight (10) side open by a left extending member (17) extending forward from the upper side of the left weight part (11), a right extending member (18) extending forward from the upper side of the right weight part (12), and a connecting member (19) connecting the front side of the left extending member (17) and the front side of the right extending member (18). A prime mover cover (28) is supported on the connecting member (19) of the cover mounting bracket (16) rotatably in a vertical direction through a hinge (31). The prime mover cover (28) is moved between an open position where an inspection opening (15) of the counterweight (10) is opened and a closed position where the inspection opening (15) is closed around the hinge (31).
