A work machine includes: a partition member provided with an intake port and an exhaust port and forming an engine room; an engine disposed in the engine room; a cooling fan disposed on an intake port side of the engine in the engine room; an exhaust pipe discharging exhaust gas from the engine; and an exhaust duct disposed in the engine room and having an inflow port into which air from the cooling fan flows, and an outflow port. At least a portion of the exhaust duct is disposed above the engine and has a facing surface facing the engine and a through-hole provided in the facing surface. At least a portion of the exhaust pipe is disposed in the through-hole. A gap is formed between an outer surface of the exhaust pipe and an inner surface of the through-hole.

A shovel includes a lower traveling body, an upper turning body turnably mounted on the lower traveling body, an attachment attached to the upper turning body, a cabin mounted on the upper turning body, and a protection member configured to protect the cabin. The protection member is provided on the attachment or the upper turning body at a position corresponding to the front of the cabin.

Provided is an electric work machine powerable by an external power supply through a power supply cable. The electric work machine includes a machine body including an electric motor, a power receiving device supplied with power through the power feed cable, connection wires extending from the power receiving device, a power feed cable connected to the machine body and a connection unit. The connection unit is disposed outside the power receiving device and connects the power feed cable and the connection wires to each other.

Power machine frames for power machines such as skid steer loaders that include features for aiding in the manufacture of the power machines, providing space saving advantages in the design of the power machine, and/or providing performance advantages for the power machine.

To provide a pipe member being able to reduce the vibration applied and improve its durability. A pipe member to be installed on the body of a construction machine has an outer main pipe and an inner auxiliary pipe inserted into the outer main pipe. An outer diameter of the inner auxiliary pipe is formed smaller than an inner diameter of the outer main pipe. The inner auxiliary pipe has a securing part secured on the outer main pipe and at least one of end parts of the inner auxiliary pipe is a free end without being secured on the outer main pipe.

To provide a construction machine capable of preventing damages of batteries placed on a machine-body frame. A construction machine comprises a machine-body frame, a supporting plate installed on the machine-body frame via elastic mounts, and batteries fixed to a topside of the supporting plate. Welding is not performed on the supporting plate.

In a hydraulic shovel including a crawler-type lower traveling body and a storage box provided at the front side of the right side of an upper rotating body, the upper face of the crawler has a stable space that can be used as a scaffold for a worker or as a temporary storage space such as a supply tank. The storage box has, at the front side of the right side, a notch that is obliquely cut from the upper side of the inner end in the left-and-right direction of the crawler to the rear side of the left and right outer sides. The notch has, at the lower side thereof, the upper face of the crawler that provides a space S usable as a scaffold for a worker or as a temporary storage space.

Shaker assemblies for dewatering slurries are disclosed. The shaker assemblies may include a positioning device which limits movement of the vibratory frame of the shaker assembly relative to a subframe when the vibratory frame is moved from a raised operating position to a lowered position. The positioning device may guide the vibratory frame as it is lowered from the raised position to the lowered position. In some embodiments, the shaker assembly includes a locking device for locking the vibratory frame to the subframe when the vibratory frame is in the lowered position.

A working machine includes a first section with a first frame and at least one oscillation axle holding a first pair of ground engaging members; a second section with a second frame and a second pair of ground engaging members; a joint arrangement pivotly connecting the first frame to the second frame; a motor configured for driving one ground engaging member of the first pair of ground engaging members in order to create propulsion forces; a propulsion force transfer arrangement adapted to transfer propulsion forces from the ground engaging member of the first pair of ground engaging members to the second pair of ground engaging members, via the joint arrangement. The propulsion force transfer arrangement includes a connecting element extending centrally in a longitudinal direction of the working machine.

The present disclosure provides methods for adjusting steering angle and articulation angle in an auto articulation operation of a work vehicle. The percentage of travel of a steering joystick of the work vehicle at least partially determines a steering desired angle change, which can be used to calculate a steering desired angle and an articulation desired angle change. The difference between the steering desired angle and a steering angle detected by a steering angle sensor is used to adjust the steering angle. The articulation desired angle change can be used to calculate an articulation desired angle. The difference between the articulation desired angle and an articulation angle detected by an articulation angle sensor is used to adjust the articulation angle.
