An actuated shear pin includes an actuator and pin body coupled to the actuator. The actuator selectively configures the pin body in a locking configuration or a stowed configuration. In the locking configuration, the pin body is placed in a travel path of two components configured to move relative to each other, to inhibit such relative movement. In the stowed configuration, the pin body is out of the travel path, thereby allowing the two components to move relative to each other.

A Multi-Armed Lifting Accessory is disclosed herein which is compact and transportable in various deployments. The Multi-Armed Lifting Accessory is advantageous and useful as it has hingedly connected loading and support arms attached to a main lifter body. The supporting arms are spring loaded allowing the Multi-Armed Lifting Accessory to stably engage with irregular shaped objects such as barge lid or a skid steer loader and allows for flexible engagement and balanced lifting operations.

A work machine comprises a tilt rotator to control rotation of a tool, a coupler to couple and decouple the tool to/from the tilt rotator, a display to output information to an operator of the work machine, an operator interface to receive input from the operator, and processing circuitry. The processing circuitry is configured to output, on the display, a rotation instruction for the operator to initiate a rotation operation of the tilt rotator, in a case that the tilt rotator is determined to be in an incorrect position, stop the rotation operation of the tilt rotator under a condition that the tilt rotator is determined to be in a correct position based on a rotation angle of the tilt rotator about a rotational axis, the rotation operation being initiated by a rotation input via the operator interface.

A working machine includes a traveling pump to be operated by power of a prime mover and deliver a hydraulic fluid; a traveling motor that rotates using the delivered hydraulic fluid; an operation valve that changes pilot pressure of a pilot fluid outputted to the traveling pump in response to operation of an operation member; an actuation valve that operates based on a control signal and changes primary pressure that is the pilot pressure of the pilot fluid supplied to the operation valve; a controller that controls opening of the actuation valve by outputting the control signal to the actuation valve; and a first detector that detects an actual number of revolutions of the traveling motor. The controller includes a changer that changes setting of the control signal such that the opening of the actuation valve increases as the actual number of revolutions of the traveling motor decreases.

A shovel includes a lower traveling body, an upper swiveling body mounted to the lower traveling body, attachments including a boom attached to the upper swiveling body, an arm attached to an end of the boom, and a bucket that is an end attachment attached to an end of the arm, and a control device configured to control swiveling of the upper swiveling body and movement of the attachments so that an end portion of the bucket moves along an extension of a slope toe, which is a target line.

A hydraulic hammer assembly includes a housing, a work tool, a fluid inlet, a fluid outlet, and a filter. The work tool is movable within the housing. The fluid inlet is configured to receive a hydraulic fluid for driving the work tool, and the fluid inlet is upstream of the work tool. The fluid outlet is for discharging the hydraulic fluid from the housing, and the fluid outlet is downstream of the work tool. The filter is positioned within the housing between the fluid inlet and the work tool.

A working vehicle includes a hitch to attach and detach an attachment thereto and therefrom, a receiver to receive wireless signal(s) which are transmitted periodically from transmitter(s) in or on the attachment(s), which include respective piece(s) of identification information of the attachment(s), and which are compliant with a near field communication standard, and a controller. The controller is configured or programmed to perform a selecting process and a predetermined process when the attachment is attached to the hitch and when a predetermined switch is operated with the attachment attached to the hitch, the selecting process including selecting, according to a predetermined condition, one of the piece(s) of identification information that is included in one of the wireless signal(s) received by the receiver, the predetermined process corresponding to the one of the piece(s) of identification information selected in the selecting process.
