Abstract (en)
In an electronic speed control device for fork lift equipment, which can be operated by a single knob or handle and features hardware comprising a single microprocessor controlled chopper circuit (1), both the elevation and the descent movement of the lift are piloted digitally using software written and stored in EPROM (14) so as to enable its subsequent modification if need be; the circuit thus controls not only the usual d.c. motor (3) coupled to the pump (5) which extends the hydraulic lift cylinder, but also the proportional valve (4) conventionally used to regulate descent. <IMAGE>
