<p>PROBLEM TO BE SOLVED: To provide rail structure for a load conveying truck suitable for a wide tread, capable of bearing large load applied onto step members and simplified in structure at the corner parts. SOLUTION: Tie rails 23, 24 are arranged almost at the center between lateral travel rails 1, 2 and a guide rail 3. Support members 25, 26 extending in the crossing direction are fixed to the important parts along the lengthwise direction of the tie rails 23, 24 to support the step members 21, 22 from below. The support members 25, 26 are composed of first support parts 25a, 26a fixed to the tie rails 23, 24 in cantilever structure toward the guide rail 3 side, and second support parts 25b, 26b fixed in twin structure between the travel rails 1, 2 and the tie rails 23, 24.</p> |
