    摘要: A hydraulic shovel is provided which comprises a pair of left and right running/rotation pedals (3L and 3R) for running or rotating a vehicle, and a single running/rotation lever 7 which is installed separately from the pedals for similarly running or rotating the vehicle. The shovel allows the operator to run or rotate the vehicle by operating on the running/rotation pedals 3L and 3R, as well as by manipulating the running/rotation lever 7. Moreover, because the running/rotation lever 7 consists of a single lever, the operator can easily manipulate it by one hand, being relieved of complicated operations and inconveniencies encountered with the conventional machine, which ensures the improved operability.

    摘要: The crawler-type travel device includes a plurality of shoe plates, a first link section, a rotational wheel, and a shaft. The rotational wheel includes a first roller and a second roller. The first roller makes contact with first end portions corresponding to axial outer ends of the first link members forming the first link section. The second roller is aligned with and disposed on the axial inner side of the first roller. The second roller is rotatable independently from the first roller. The second roller makes contact with second end portions corresponding to axial inner ends of the first link members.

    摘要: Right and left track adjusters each comprise a tension adjusting cylinder operable in forward and backward directions in the same condition; a motor-driven hydraulic pump; and a direction selector valve disposed in a hydraulic circuit for connecting the motor-driven hydraulic pump to the tension adjusting cylinder. The hydraulic circuit includes operating condition detecting means for detecting the operating condition of the tension adjusting cylinder. A controller located in the work vehicle judges a signal released from the operating condition detecting means. If the pressure condition is determined to be higher than a preset value, the tension adjusting cylinder is moved backward to avoid abnormal tension in the crawler belt. If it has a steady-state value, the movement of the tension adjusting cylinder is controlled according to a judgment based on a set value corresponding to the traveling direction of the vehicle, thereby properly adjusting the tension of the crawler belt.
