Abstract
A hydraulic shovel is provided which comprises a pair of left and right running/rotation pedals ( L and R) for running or rotating a vehicle, and a single running/rotation lever 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 L and R, as well as by manipulating the running/rotation lever Moreover, because the running/rotation lever 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.
