Abstract: A work machine capable of suppressing a piston of a hydraulic cylinder reaching a stroke end is provided. The work machine includes a vehicular body, a work implement supported on the vehicular body, a hydraulic cylinder that drives the work implement, an issuance apparatus that issues a warning, and a controller that controls the hydraulic cylinder and the issuance apparatus. The hydraulic cylinder includes a cylinder portion and a piston capable of carrying out reciprocating movement within the cylinder portion. The controller can control the issuance apparatus to issue a warning when the piston reaches a warning issuance position before the stroke end of the hydraulic cylinder, and can adjust timing of issuance of the warning.

Abstract: The hydraulic excavator includes a vehicle body, a work implement , a display section, a detection section , and a display control section. The vehicle body includes a driver’s seat . The work implement is attached to the vehicle body and operates with respect to the vehicle body. The display section is provided on the work implement. The detection section detects an object in a region on a side opposite to the driver’s seat with respect to the work implement around the vehicle body. The display control section displays the information detected by the detection section on the display section.

Abstract: A filter attachment body is attached to a vehicle body of a work vehicle provided with a pump. The filter attachment body includes a bracket attached to the vehicle body, a filter device attached to the bracket, and a plurality of elastic members interposed between the bracket and the filter device. The bracket has an attachment plate to which the filter device is attached. The attachment plate is disposed substantially perpendicular to an up-down direction. The filter device has a filter case connected to the pump, and a filter body attached to the filter case. A geometric center of the filter body overlaps a figure drawn by linking the elastic members with straight lines when viewed from a top view of the attachment plate. At least a portion of at least one of the elastic members is located outside of the filter body when viewed from the top view.

Abstract: A control apparatus of a press machine in which a motor performance torque is fluctuated in accordance with a rotational angle of the rotating body in the case of rotating the motor at a fixed instruction speed. The control apparatus includes an angle detecting apparatus detecting a rotational angle of the rotating body, a torque determining apparatus determining a necessary motor torque in correspondence to a characteristic of the press machine on the basis of a value of the rotational angle input from the angle detecting apparatus, and a speed adjusting apparatus increasing the rotational instruction speed of the motor to a value more than the fixed instruction speed, at the rotational angle of the rotating body in which the necessary motor torque becomes smaller than a predetermined motor torque reference value.
