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.
