PROBLEM TO BE SOLVED: To provide a carrying truck capable of smoothly elevating a fixed wheel during nesting. SOLUTION: The carrying truck includes: a pair of turning frames 4a and 4b having turning wheels 6 attached thereto; a connection frame 5 which connects the frames and to which a fixed wheel 7 is attached; a cylindrical body 9 fitted, so as to be vertically movable, to a support 8a erected on one turning frame 4a at one end of the connection frame 5; rotary members 10 supported pivotally and respectively on the right and left sides of the support 8a; pallet 2 attached to both rotary members 10 to vertically and rotatably move; and an elevation operation member 12 for elevating the cylindrical body 9 side of the connection frame 5 following the vertical rotation of both rotary members 10. The elevation operation member 12 includes: pivotally-supported parts 13 respectively supported by the right and left rotary members 10; and a suspension part 14 for suspending the connection frame 5 from a lower side between the pivotally-supported parts 13 of both sides. Thus, the fixed wheel is smoothly elevated during nesting. COPYRIGHT: (C)2012,JPO&INPIT |
