A motor drive control circuit that controls opening and closing of a drive power source from a battery to drive and control a cargo handling motor of a battery forklift; and a motor drive control circuit that detects an over-discharge state of the battery and controls the motor drive. An over-discharge lock device that disables the power closing operation of the circuit and stops the cargo handling motor; and an over-discharge lock device that forcibly disables the motor drive control circuit that has been disabled by the over-discharge lock device when the battery is over-discharged by operating a release switch. 1. A release device for an over-discharge lock device in a battery forklift, comprising a release circuit for releasing the lock. 2. The motor drive control circuit consists of a start switch, a cargo handling limit switch that is controlled on and off based on the operation of the lift tray and tittle lever, and a cargo handling contactor that opens and closes contacts connected in series with the cargo handling motor. The over-discharge lock device includes a lock contact that opens when the battery is over-discharged, and the contact is connected in series between the start switch and the cargo handling limit, while the release circuit connects the release switch to A release device for an over-discharge lock device in a battery forklift according to claim 1, which is connected in parallel to the series circuit of the starting switch and the lock contact. 3. The start switch and release switch are one key switch that has a start contact corresponding to the start switch and a release contact corresponding to the release switch, and the release contact is a contact that automatically returns. A release device for an over-discharge lock device in a battery forklift according to scope 2.
