Method for operating an industrial truck and industrial truck provided for it

摘要

In a method for operating an industrial truck, a load-lifting member (1) is moved up and down vertically on a lift mast (2). A discrete control signal is provided to control the vertical speed of the load-lifting member (1) by at least one single or multistage switch. In switching on and then holding the switch (13) in the on position, the load-lifting member (1) is first accelerated from zero to a first vertical speed value (V1) and after the passage of a period of time T1, it is accelerated to a second higher vertical speed value (V2).
