This is performed only when 0 is fully open, and collision between the second pallet 17 and the deck plate 40 is prevented.

The seventh and eighth electromagnetic contactors 67 and 68 are connected to deck open and deck close limit switches 59 and 68, respectively.
60 normally closed contacts 59b and 60b are connected in series. Each series connection is selectively connected between the control power supply via the deck open/close switch 69, and the common wiring section is connected to the normally open contact 56a of the first lower limit switch 56 and the second lower limit switch 56.
Normally open contacts 57a of the upper limit switch 57 are connected in series. As a result, when the deck opening/closing switch 69 is set to the opening contact a, the seventh electromagnetic contactor 67 is connected.
The deck motor 45 operates in the opening direction to move the deck plate 40 in the opening direction, and when the deck plate 40 reaches the fully open position, the normally closed contact 5
Since the opening 9b is opened, the movement of the deck plate 40 is stopped. If the deck opening/closing switch 69 is set to the closing contact b, the deck motor 45 operates in the opening direction and the deck plate 40 moves in the opening direction, and when the deck plate 40 reaches the fully open position, the normally closed contact 59
Since b is opened, the movement of the deck plate 40 is stopped. However, this operation is performed when the first pallet 15 is in the lowered position or
This is done only when the pallet 17 is in the raised position; otherwise, the normally open contact 56a or the normally open contact 57a is open, so the deck plate 40 does not move. 2 pallets 15
