摘要： A control device of a forklift engine that secures operability by keeping down fuel consumption when the accelerator pedal is floored in an unloaded or lightly loaded state, and once a heavy cargo is loaded, by lifting the cargo at a maximum lifting speed and traveling with maximum travel performance without acceleration problems. At least two maximum torque curves of different magnitudes are set in advance on a torque curve diagram. Then, the weight the cargo loaded on an attachment is measured. A threshold value for selecting at least two maximum torque curves is determined. If the measured weight is less than the threshold value, the maximum torque curve with a smaller maximum torque value is selected. If the measured weight is not less than the threshold value, the maximum torque curve with a larger maximum torque value is selected. The engine is controlled using the selected maximum torque curve.

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.

摘要： In an engine-overrun-preventing control device, if an engine speed exceeds a maximum speed, a minimum value of an inching rate is set such that higher the actual engine speed results in a higher minimum value of an inching rate. The hydraulic pump displacement is adjusted to obtain a higher inching rate between the minimum value of the inching rate and an inching rate set based on a brake stroke. If the engine speed exceeds a commanded speed and a pressure time-rate-of-change at the pump intake exceeds a prescribed value, the minimum value of the inching rate is set such that the higher the pressure time-rate-of-change, the higher the minimum value of the inching rate. The pump displacement is adjusted to obtain a higher inching rate between the minimum value of the inching rate set based on the pressure time-rate-of-change and the inching rate set based on the brake stroke.
