Description
technical field [0001] The invention relates to the technical field of forklift manufacturing, in particular to a device and method for controlling the lifting speed of a forklift for an internal combustion counterbalanced forklift with an electronic accelerator engine or an electronic accelerator actuator. Background technique [0002] At present, the lifting process of the internal combustion forklift mast is realized as follows: while the operator controls the multi-way valve operating lever with his hand, he steps on the accelerator pedal to increase the speed of the engine, and drives the oil pump to provide enough flow to lift the cargo. During the lifting process, it is difficult to accurately control the engine speed. When the valve core is not fully opened, if the engine speed is too high, the hydraulic oil will overflow and return to the fuel tank, which will cause the temperature of the hydraulic oil to rise and the fuel consumption to increase. . In addition, du...
