A work machine comprises an armrest and a user control operable by the user to control tool or machine functions when the user's arm rests on the armrest. An armrest sensor is configured to sense the presence of the user's arm and to disable the control when the user's arm is removed from the armrest. The control may be mounted on the armrest and the armrest movable between enabling and disabling positions by the weight of the user's arm. A seat sensor may be configured to disable the control when the user leaves the seated position.

A shovel including a lower-part traveling body, an upper-part swiveling body which is enabled to swivel and is mounted to the lower-part traveling body, an actuator, and a control device that implements a first control process that causes the actuator to act autonomously, and a second control process that causes the actuator to act autonomously, wherein the control device is configured to select one control unit from among a plurality of control units that implements the first control process and the second control process, as a priority control process that is given priority to act, in a case where a conflict is judged to occur among the plurality of control units that implements the first control process and the second control process.

A payload detection system for automated payload tip-off of a loading operation includes a tip-off controller. The tip-off controller is configured to receive a signal of a remaining payload target; receive a signal of a material weight within an implement and a signal of an angle of the implement; and determine a tip-off threshold based on the material weight and the remaining payload target. The tipoff controller initiates a bulk dump sequence if a difference between the material weight and the remaining payload target is greater than the tip-off threshold and initiates a slow dump sequence if the difference is below the tip-off threshold. The bulk dump sequence includes a single implement actuation to induce material spill until the tip-off threshold is met and the material is staged. The slow dump sequence includes a plurality of dump then rack actuations to induce and then prevent material spill until the remaining payload target is met, each dump actuation having an associated dump angle and each successive dump angle is progressively smaller.

A shovel management apparatus configured to manage a shovel including a lower traveling body, an upper turning body mounted on the lower traveling body via a turning mechanism, and an excavation attachment attached to the upper turning body includes a memory and a processor coupled to the memory. The processor is configured to obtain fuel consumption information regarding the fuel consumption of the shovel and work mode information indicating the work mode of the shovel set by an operator and aggregate the fuel consumption information according to the work mode.

A work machine includes a traveling body, a work attachment, and a processing circuitry configured to receive a reservation of an execution of a predetermined function in accordance with an input received by the work machine or in accordance with a signal received from an external apparatus and execute the predetermined function of the reservation, based on an execution condition designated by the reservation.

An excavator includes a lower traveling body; an upper turning body turnably mounted to the lower traveling body; an acquisition device mounted to the upper turning body and configured to acquire information including a status around the excavator; and a control device configured to recognize a reference object that is in a stopped state or at a fixed position around the excavator based on the information acquired by the acquisition device, and to estimate a turning angle of the upper turning body based on a change in a position of the reference object as viewed from the upper turning body.

A method for controlling a loading tool includes positioning the loading tool on a lifting device of a machine, receiving a payload by the loading tool from a payload stock during an operating mode, and determining a mass of the payload during the operating mode. The method also includes providing calibration data representative of a ratio between a volume of the payload and a mass of the payload, detecting a volume of the payload during the operating mode, and determining the mass of the payload as a function of the detecting step and the calibration data.

A work machine includes a plurality of constituent portions including a first portion. A system for the work machine includes a storage device, an input device, and a controller. The storage device stores center of gravity positions of the plurality of constituent portions. The input device receives input of a first parameter for determining the center of gravity position of the first portion. The controller calculates a center of gravity position of the entire work machine based on the center of gravity positions of the plurality of constituent portions. The controller sets the center of gravity position of the first portion by using the first parameter when the first parameter is inputted with the input device. The controller sets the center of gravity position of the entire work machine based on the center of gravity positions of the plurality of constituent portions that include the set center of gravity position of the first portion.

A heavy-duty interactive (HDi) system may include a heavy-duty vehicle; a work tool installed on the heavy-duty vehicle; a memory that stores a plurality of patterns representing operation events for the heavy-duty vehicle; a first sensor affixed to the heavy-duty vehicle that collects first sensor data as the heavy-duty vehicle is operated; a second sensor affixed to the work tool that collects second sensor data as the work tool is operated; and a controller operatively coupled to the first sensor, the second sensor, and the memory. The controller may be configured to identify a heavy-duty vehicle operation event by comparing at least one of the first sensor data and the second sensor data with the plurality of patterns in the memory, and associate the work tool with the heavy-duty vehicle based on a comparison of the first sensor data and the second sensor data.
