A work machine includes a plurality of actuators and an operation receiving unit for receiving a plurality of operation inputs concerning the plurality of actuators. In a first mode, one actuator among the plurality of actuators operates by one operation input among the plurality of operation inputs. In a second mode, two or more actuators among the plurality of actuators operate by the one operation input. In the second mode, in response to another operation input different from the one operation input among the plurality of operation inputs, an actuator other than the two or more actuators among the plurality of actuators is operated, or a parameter concerning the actuator that operates by the one operation input among the plurality of actuators is adjusted.

Work machine and information processing apparatus

The shovel includes an attachment including a boom; an arm; and a bucket, wherein the bucket includes a first part and a second part, shapes of the first and second parts being mutually different, and wherein the attachment performs, in response to an operation of the attachment, a first action or a second action, the first operation causing the attachment to activate such that the first part moves along a predetermined trajectory, and the second operation causing the attachment to activate such that the second part moves along another predetermined trajectory, and wherein the shovel is configured to switch, based on at least one from among a state of the shovel and a circumference state of the shovel, between a case where the first action is performed and a case where the second action is performed.

Shovel

A shovel includes a lower traveling body; an upper turning body pivotably attached to the lower traveling body; an attachment attached to the upper turning body; and a processor that stores in a memory, or transmits to an external device, log information including information on the shovel and information on a peripheral environment of the shovel upon detecting that a degree of stability on a motion of the shovel becomes less than a predetermined reference level, or upon detecting an indication that the degree of stability on the motion of the shovel becomes lower than the predetermined reference level.

Shovel, information processing device, information processing method, and non-transitory storage medium

A shovel includes a traveling body, a turning body mounted on the traveling body, a work attachment including a boom attached to the turning body, an arm attached to an end of the boom, and an end attachment attached to an end of the arm, and a processor coupled to a memory storing instructions and configured to read and execute the instructions stored in the memory to control a turning operation of the turning body in accordance with a predetermined operation of the work attachment to cause the end attachment to perform the predetermined operation as seen in a plan view in response to an operation by an operator.

An electric swiveling type construction machine includes a lower travelling body, an upper swivel body which is turnably mounted on the lower travelling body, a boom in which one end is rotatably attached to the upper swivel body, an arm in which one end is rotatably attached to the other end of the boom, a working element which is rotatably attached to the other end of the arm, a brake mechanism which holds the upper swivel body, a swiveling motor which swivels and drives the upper swivel body, a state monitoring unit which monitors the state of the brake mechanism, and a controller which detects releasing of braking performed by the brake mechanism based on the monitor by the state monitoring unit. The swiveling motor does not generate a force until the controller detects the releasing of the brake.

A control method of measuring an internal resistance of an electric power accumulatorof a hybrid-type construction machinecomprises: a pattern generating step of generating an internal resistance measurement pattern in a non-operation status in which there is no operation for the hybrid-type construction machine from an operator; an output changing step of changing an output of a generatorbased on the pattern generated in the pattern generating step in the non-operation status; an electric current, etc., detecting step of detecting electric current values and voltage values in the electric power accumulatorbefore and after the change of the output of the generatorin the output changing step; and an internal resistance measuring step of measuring the internal resistance of the electric power accumulatorbased on the electric current values and the voltage values detected before and after the change of the output of the generatorin the electric current, etc., detecting step.

Control method and a control apparatus in a hybrid type construction apparatus

When a hybrid-type construction machine including an electric power accumulator is started under a low-temperature environment, at first an ignition key of an engine is turned on to drive the engine. If the temperature of the electric power accumulator is lower than a predetermined temperature, the electric power accumulator is heated by driving the engine. Further, if the temperature of the electric power accumulator is lower than the predetermined temperature, the engine is driven to carry out a warm-up operation and a motor generator is driven to charging and discharge the electric power accumulator to thereby heat the electric power accumulator.
