A urea water tank (11) is provided with a unit insertion opening (12H) that is disposed on a top surface part (12A) of a tank body (12) and opens more largely than an external dimension (D2) of a sensor unit (20), a sensor mounting member (16) that is disposed on the top surface part (12A) of the tank body (12) and closes the unit insertion opening (12H), and a filter which is formed as a tubular body to surround the sensor unit (20), and inserted in the unit insertion opening (12H) of the tank body (12) from a lower end (24A4)-side, and having an upper end (24A3) mounted on the top surface part (12A) of the tank body (12) by using the sensor mounting member (16).

There is provided a working vehicle capable of simplifying a structure and reducing manufacturing costs by realizing a configuration in which a tying-down attachment point doubles as a lifting attachment point. A working vehicle according to the present invention includes tying-down attachment points for locking a tightening member for preventing reversal at the time of transportation or parking in at least the front of a vehicle body, in which the tying-down attachment points are arranged at right-and-left two places on a front end surface of the vehicle body, capable of locking a lifting member for lifting the vehicle body upward and having strength in a vertical direction enough to withstand a load applied at the time of lifting the vehicle body upward after locking the lifting member, thereby doubling as lifting attachment points.

A construction machine in which an electrical unit can be reliably cooled at low cost by effectively utilizing an intake pipe connected to an intake port of an engine. This construction machine includes: an engine; and a hood covering the engine, wherein a space inside the hood has a placement space in which an electrical unit is placed and which communicates with outside air, and a distal-end opening of an intake pipe connected to an inlet port of the engine is disposed in the placement space to cause outside air sucked into the intake pipe due to a suction pressure occurred in the intake pipe to pass through the placement space to form a cooling air path in the placement space.

A pivoting connection between a bucket and a padlock of a rope shovel, a pin assembly, and a rope shovel are disclosed. A pivoting connection includes a pin having a pin axis and extending through a bucket lug of the bucket and a pair of padlock lugs of the padlock; a flag having a pin end and a mounting end; a locking coupling coaxial with the pin axis and located in the pin end of the flag, wherein the locking coupling selectively couples the flag to the pin; and a slotted flag mount attached to the bucket including a vertical slot and a horizontal slot parallel to the pin axis; wherein the mounting end of the flag is received by the slotted flag mount such that the pin is constrained from rotating with respect to the bucket and from translating along the pin axis.

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 pedal operation switching mechanism can switch a foot pedal to any movement pattern of three movement patterns of a front/rear step pattern of being capable of the operation of depressing a front side of the foot pedal from a neutral position of a rotational part of a pilot valve and of being capable of the operation of depressing a rear side of the foot pedal from the neutral position of the rotational part, a front step limit pattern of being capable of the operation of depressing only the front side of the foot pedal from the neutral position of the rotational part, and a fixing pattern of fixing the movement of the foot pedal in the neutral position of the rotational part.

A bushing assembly comprises a flanged bushing including a flange portion including a flange anti-rotation feature, and a shaft portion with an outer cylindrical surface extending from the flange portion, terminating at a free end, the outer cylindrical surface including external threads disposed proximate the free end, and a retaining ring including an annular configuration defining an inner cylindrical surface defining internal threads complimentarily shaped to mate with the external threads of the outer cylindrical surface.

An operator seat is arranged in a cab. An air-conditioning unit is arranged in front of the operator seat. A lower window through which the outside can be seen from the inside of the cab is arranged in front of the operator seat and laterally to the air-conditioning unit.

A bucket wheel assembly (40) includes a structural frame (42) that in use forms a structural part of the boom of a bucket wheel reclaimer. The structural frame (42) supports a bucket wheel (44) having a plurality of attached buckets (46); a ring chute (48) and an associated discharge chute (50). The bucket wheel (44) is attached to the middle of shaft (51), which is supported by two bearings (52). The drive unit is attached to the shaft (51) to provide the rotation torque, and the drive unit is also attached to the structure (42). The structural frame (42) couples to a portion of the boom and transfers the assembly load to the boom when the reclaimer is in operation.
