Abstract
Official abstract text for this publication.
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 a 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 a 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
First claim
Opening claim text (preview).
1 . A forklift comprising: an engine; a travel hydraulic pump which is a variable displacement pump driven by the engine; a hydraulic motor which forms a closed circuit with the travel hydraulic pump and is driven with working fluid discharged from the travel hydraulic pump; a driving wheel driven by the hydraulic motor; a lift pressure detecting device which detects lift pressure in a lift cylinder which raises or lowers a fork for mounting a load; a pump pressure detecting device wh…
