Power control device for cargo handling vehicle

摘要

A power control device for a cargo handling vehicle provided with a cargo handling apparatus operated by a hydraulic oil from a hydraulic pump driven by an engine includes a controller and an engine speed sensor detecting an engine speed. The controller controls an engine torque to be limited by using an engine torque limit value for limiting the engine torque, and controls the engine torque limit on the engine by an engine torque limiting unit to be canceled when the engine speed detected by the engine speed sensor is equal to or lower than a predetermined first engine speed.

1. A power control device for a cargo handling vehicle provided with a cargo handling apparatus operated by a hydraulic oil from a hydraulic pump driven by an engine, the power control device comprising:
engine torque limiting means for controlling an engine torque to be limited by using an engine torque limit value; engine speed detection means for detecting an engine speed; and engine torque limit cancelling means for controlling a torque limit on the engine by the engine torque limiting means to be canceled when the engine speed detected by the engine speed detection means is equal to or lower than a predetermined first engine speed, wherein the engine torque limiting means sets the engine torque limit value to a predetermined value when the engine speed detected by the engine speed detection means is equal to or higher than a second engine speed higher than the first engine speed.
