This invention relates to a hydraulic circuit for a forklift, and intends to lift a fork for lifting in high speed, or to inch the fork little by little, as occasion demands. In this hydraulic circuit, a first electric motor for driving a first electric motor disposed on a first route extending from a tank to a lift cylinder is on-off controlled. A check valve disposed on the first route downstream of the first hydraulic pump allows only an oil-flow from the oil tank to the lift cylinder. A second motor for driving a second electric motor disposed on a second route extending from a tank to a lift cylinder is PMW-controlled. A flow controlling valve is disposed on the second route downstream of the second hydraulic pump and including an electro-magnetic valve operated associating with the PMW-controlling of said second electric motor. A separating element hydraulically separates the check valve and the electro-magnetic valve of the flow controlling valve.
