Lift truck i.e. counterbalanced lift truck, controlling method, involves regulating normal and reduced characteristic curves of torque by control unit according to rotational speed in normal and economy energy modes, respectively

摘要

The method involves sending a signal to a control unit by a wireless receiving unit i.e. radio frequency identification (RFID) receiving unit, for regulating a normal mode and an economy energy mode. A normal characteristic curve (20) of torque is regulated by the control unit according to the rotation speed in the normal mode. A reduced characteristic curve (21) of the torque is regulated by the control unit according to the rotation speed in the economy energy mode.
