Forklift and method for controlling forklift
A forklift includes a hydraulic pump being a variable displacement pump driven by an engine, a hydraulic motor driven with fluid from the pump, a storage storing first and second groups, and a predetermined lift pressure setting value, the first group including output characteristics each representing relation between a rotational speed of the engine and a torque of the engine for each lift pressures, the second group including output characteristics each representing relation between the rotational speed and the torque for each pump pressures, and determining a greater one of first and second torques as a target torque of the engine, the first torque being calculated from one selected from the first group using the lift pressure setting value or an actual lift pressure and the rotational speed, the second torque being calculated from one selected from the second group using the pump pressure and the rotational speed.
