PROBLEM TO BE SOLVED: To notify an operator that no pallet is inserted into a fork by applying an output signal of a operation stand height detector and an instruction signal for raising the operation stand and by providing an alarm actuation controller for actuating the alarm. ;SOLUTION: A photoelectric sensor 9 below an operation stand 4 and at a position deflected to either one side from the center of the operation stand 4 is fixed with a light axis oriented backward parallel to the running road face and the horizontal direction. The photoelectric sensor 9 is provided with a light projection part and a light reception part. An operation stand height detector is composed of fixing a tog to the operation stand 4, and the operation stand 4 reaches its specified height when the operation stand raises and the tog actuates a limit switch. When the tog actuates the limit switch, the output signal at this time applies to an alarm actuation controller, and if the photoelectric sensor 9 is actuated, the alarm actuation controller sounds an alarm 11.;COPYRIGHT: (C)1997,JPO
