Description

This invention relates to a material handling device. Conventionally, a material transport device for conveying materials is known, as described in Patent Document 1. The material transport device described in Patent Document 1 is equipped with a long frame. The frame comprises a main body with a running section and an extension section extending from the end of the main body. In such a material transport device, materials were transported by suspending them from suspension sections provided on the underside of the long members of the main body and the extension section.

The embodiments of the present invention will be described in detail below with reference to the drawings. In the drawings, identical or equivalent elements are denoted by the same reference numerals, and redundant descriptions are omitted. [First Embodiment] Figure 1 is a side view showing a material conveying device according to the first embodiment of the present invention. Figure 2 is a plan view of the material conveying device according to the first embodiment of the present invention. Figure 3(a) is a side view showing the material conveying device in the process of being extended. Figure 3(b) is a side view showing the material conveying device in the extended state. Figure 4 is a cross-sectional view along the line IV-IV in Figure 1. As shown in Figures 1 and 2, the material transport device 100 is a device that suspends and transports material W1 to a predetermined position. The material transport device 100 comprises a frame 2, swivel-type travel sections 3A and 3B (travel section and lateral section), lifting sections 6A and 6B, and a hand-operated support section 7. The material transport device 100 travels on the ground. The frame 2 is a long member extending in the direction in which the material W1 is transported. The direction in which the frame 2 extends is sometimes referred to as the "longitudinal direction D1." The direction perpendicular to the longitudinal direction D1 in the direction parallel to the ground is sometimes referred to as the "lateral direction D2." Here, within the longitudinal direction D1, the side transporting the material W1 is sometimes referred to as the "front," and the opposite side as the "rear." Furthermore, within the lateral direction D2, the side towards the center of the material transport device 100 is sometimes referred to as the "inside," and the side moving away from the center is sometimes referred to as the "outside." The frame 2 comprises a main body 2A with swivel-type travel sections 3A and 3B at both ends in the longitudinal direction D1, and an extension section 2B that can be positioned to extend from the front end of the main body 2A in the longitudinal direction D1. The extension section 2B can transition from a state where it is housed in the main body 2A (state in Figure 1) to a state where it is extended forward (state in Figure 3(b)). The main body portion 2A of the frame 2 includes a pair of elongated members 11 that extend straight in the longitudinal direction D1 at both ends in the lateral direction D2. The elongated members 11 extend at least longer in the longitudinal direction D1 than the material W1. The elongated members 11 are arranged spaced apart from each other so as to be aligned in the lateral direction D2. The extension portion 2B of the frame 2 includes a pair of elongated members 12 that extend straight in the longitudinal direction D1 at both ends in the lateral direction D2. The elongated members 12 extend at least longer in the longitudinal direction D1 than the material W1. Each elongated member 12 is arranged to be housed within each elongated member 11 in a manner that allows it to move in the longitudinal direction D1. The frame 2 has an extension jack 50 that extends and retracts the extension portion 2B relative to the main body portion 2A. The telescopic jack 50 allows adjustment of the amount by which the long member 12 of the extensio
