    摘要： In construction machinery, control is conducted to keep a work machine to operate at a constant speed regardless of the operation thereof. Different engine output lines T0-T3 and pump torque lines M1-M4 are defined for different operation types. All the matching points of the engine output lines T0-T3 and pump torque lines M1-M4 designate a constant engine speed N1. One engine output line and one pump torque line are selected according to the operation type presently selected. An output horsepower of the engine is controlled on an equal horsepower line corresponding to a sum of a horsepower for an auxiliary machine and a horsepower at a matching point of the selected lines. The pump torque for the work machine is controlled on the selected pump torque line. The engine operates at a constant speed N1 even when the operation type varies or the horsepower for the auxiliary machine changes.

    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.
