ENGINE LOAD CONTROL DEVICE OF WORK VEHICLE
An engine load control device (30) is installed in a wheel loader (50) that transmits an output of an engine (1) to hydraulic actuators such as a loading hydraulic cylinder (14) via variable displacement type hydraulic pumps such as a loading hydraulic pump (8). A controller (18) calculates, based on a target rotational speed and an actual rotational speed of the engine (1) that are detected by an engine rotational speed sensor (1a) and a stroke sensor (17a), an approaching rate ± between the numbers per unit time, and adjusts the maximum absorbing torques of the hydraulic pumps (7 to 9) according to the magnitude of the approaching rate ±.
