MULTISTAGE PARKING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a multistage parking device capable of doing work for adjusting and inspecting a switch to detect where a parking pallet is moved down and stopped without requiring labor for maintenance workers to enter a pit. SOLUTION: A position detecting cam 11 is mounted near one end 10a of a lifting chain 10 wound on a sprocket 8 for a driver and a switch 12 is provided on a fixed body for operating with the engagement of the cam 11 so that where a lower stage parking pallet 5 is moved down and stopped is detected with the operation of the switch 12. In this way, in the condition that the lower stage parking pallet 5 and an upper stage parking pallet is stopped at a move-down and stop position, a separation cover provided at the side of the upper stage parking pallet is removed to open an inspection port and then work for adjusting and inspecting the cam 11 and the switch 12 is done from a ground via the inspection port.
