  • Patent number: 12060697
    Abstract: A work machine includes: a machine body; an actuator attached to the machine body; an operation device used to operate the actuator; an operation sensor that senses an operation of the operation device; a photographing device that photographs surroundings of the machine body; a video data recording device that records video data including video photographed by the photographing device; a controller that controls the video data recording device; and an object sensor that senses an object in the surroundings of the machine body. The controller determines whether or not a recording and retaining condition including a condition that an object is present in the surroundings of the machine body and a condition that the operation device is operated is satisfied on the basis of a result of sensing in the object sensor and a result of sensing in the operation sensor, and makes the video data recording device record and retain the video data when the recording and retaining condition is satisfied.

  • Patent number: 6561940
    Abstract: An output rotational driving power of the engine is split into a first split power and a second split power. The first split power is transmitted to a continuously variable speed transmission that transmits the first split power by a shearing resistance of a fluid. The second split power is transmitted to a differential planetary gear system. An output power of the continuously variable speed transmission is transmitted to the differential planetary gear system to combine the first split power and the second split power in the differential planetary gear system. A variation of a rotating speed of the output rotational driving power is absorbed by the continuously variable speed transmission to adjust an output rotating speed of the differential planetary gear system to a constant speed.
