PROBLEM TO BE SOLVED: To reduce the number of a pallet carrying axes, eliminate need of adjustment, simplify installation, standardize work machine bodies, eliminate fixing of a pallet on the work machine side, and provide a common unit to reduce cost. SOLUTION: A pallet charging station 31 and a pallet discharging station 33 are provided at a lower part in a multi-stage housing rack 11, a first lifter 35L provided with a first traverser 39L is vertically movably provided on one side of the housing rack 11, and a second lifter 35R provided with a second traverser 39R is vertically movably provided on the other side of the housing rack 11. Since a pallet P having works W is thus carried by the first and the second lifters 35L, 35R, the number of axes is reduced to four, and by providing a common unit and simplifying installation, the cost can be reduced. |
