<p>PROBLEM TO BE SOLVED: To provide a carriage lifting device that is used when moving a hand carriage for carrying loads over a step difference, which allows the carriage to be moved smoothly even though a pit is omitted, unlike a conventional manner that allows the carriage to be smoothly moved by placing a base in the pit provided on a placement surface so that a table is mated to the placement surface when the table reaches a descent end thereof.SOLUTION: At both sides of a table 3 on which a carriage 20 is mounted are provided wheel-travelling portions 3b and 3b for travelling wheels 22 to 22. The wheel travelling portions 3b and 3b are provided to be lower by one stage than a central portion 3a of the table 3 and set to be mated to a placement surface at a descent end position of the table 3. This allows the carriage 20 to be smoothly moved between the placement surface and the table 3 and allows a conventional pit to be omitted.</p> |
