<P>PROBLEM TO BE SOLVED: To provide a cargo receiving platform elevating device capable of preventing such phenomenon as a tip end of the cargo receiving platform jumps. <P>SOLUTION: The cargo receiving platform elevating device includes a cargo receiving platform 5 which ascends/descends between a cargo platform and a ground and can be tilted on the ground, a lift arm 3 in which one end supports a base end of the cargo receiving platform 5, a power unit 100 which ascends/descends as well as tilts the cargo receiving platform 5 that is supported by the lift arm 3, and a sensor 6 which detects that the cargo receiving platform 5 has been tilted. When the sensor 6 detects tilting of the cargo receiving platform 5 along the direction in which the tip end of the cargo receiving platform 5 is grounded, the power unit 100 keeps tilting of the cargo receiving platform 5 along the direction in which the tip end of the cargo receiving platform 5 is grounded over a predetermined time period. <P>COPYRIGHT: (C)2012,JPO&INPIT |
