摘要:
An engine control device for a forklift that suppresses an increase in fuel consumption amount and noise by limiting an engine rotation speed when the forklift is driven without the need to increase the engine speed according to the accelerator operation even when the accelerator is depressed hard. Determining means in a controller determines whether all of the following conditions are satisfied: a neutral position of the traveling direction instructing means; a lift raising switch and first, second and third attachment switches are turned off. When all of the above conditions are satisfied, it is determined whether the forklift is driven in any of a plurality of states. An engine control means generates and outputs a control command to obtain the engine speed based on the accelerator pedal depression with the upper limit value of the engine speed set as an upper limit value of the engine speed.
