A system for conveying material is disclosed. The system may include a base assembly including at least one proximal leg movably, and a plurality of wheels configured to move between a transport position in which the plurality of wheels is adjacent to the base, and a working position in which the plurality of wheels is spaced from the base relative to the transport position, wherein the at least one proximal leg is configured to move between a retracted position in which the plurality of wheels supports the system on a ground surface, and an extended position in which the at least one proximal leg supports the system on the ground surface and at least one wheel of the plurality of wheels does not support the system on the ground surface; a conveying assembly; and a support assembly configured to move the conveying assembly between storage and operating positions. |
