1. A bulk material storage apparatus operable to be transported on a trailer bed and stationed on a ground surface, wherein the apparatus comprises:
one or more containers, wherein each of the one or more containers defines a volume for holding a bulk material; and a frame to support the one or more containers and defining a first frame plane along a first side of the apparatus and a second frame plane along a second side of the apparatus opposite the first side of the apparatus, wherein the frame comprises:
at least two leg members spaced apart about a perimeter of the apparatus, wherein each of the at least two leg members comprises:
an upper leg portion extending from a bottom end region to a top end region along a vertical axis, wherein the top end region is located adjacent the one or more containers, anda lower leg portion comprising a foot member operable to engage the ground surface, wherein the lower leg portion is adjustably coupled to the bottom end region of the upper leg portion for adjustment along the vertical axis between at least a retracted position and an extended position, wherein the foot member is operable to engage the ground surface to support the apparatus on the ground surface when the lower leg portion is in the extended position, wherein the foot member is located closer to the bottom end region of the upper leg portion when the lower leg portion is in the retracted position than when the lower leg portion is in the extended position,a plurality of cross members configured to support the at least two leg members as spaced apart about the perimeter of the apparatus, andat least two lift apparatuses, wherein each of the at least two lift apparatuses comprises:
a fixed portion fixedly attached to at least one of the plurality of cross members and the upper leg portions of the at least two leg members, anda lift member comprising an engaging member operable to engage the trailer bed, wherein the lift member is adjustably coupled to the fixed portion for adjustment along a vertical axis between at least a non-advanced position and an advanced position, wherein the engaging member engages the trailer bed to support the apparatus on the trailer bed when the lift member is in the advanced position, wherein the lift member is offset from one of and located between the first frame plane and the second frame plane, wherein the apparatus is configurable in at least a transport configuration, a first transition configuration, a second transition configuration, and a stationary configuration,
wherein the lower leg portion of each of the at least two leg members is in the retracted position, the lift member of each of the at least two lift apparatuses is in the non-advanced position, and at least a portion of the frame is operable to engage the trailer bed to support the apparatus on the trailer bed when the apparatus is in the transport configuration,wherein the lower leg portion of each of the at least two leg members is in the retracted position and the lift member of each of the at least two lift apparatuses is in the advanced position operable to engage the trailer bed with the engaging member to support the apparatus on the trailer bed when the apparatus is in the first transition configuration,wherein the lower leg portion of each of the at least two leg members is in the extended position operable to engage the ground surface with the foot member to support the apparatus on the ground surface and the lift member of each of the at least two lift apparatuses is in the advanced position operable to engage the trailer bed with the engaging member to support the apparatus on the trailer bed when the apparatus is in the second transition configuration, andwherein the lower leg portion of each of the at least two leg members is in the extended position operable to engage the ground surface with the foot member to support the apparatus on the ground surface and the lift member of each of the at least two lift apparatuses is in the non-advanced position when the apparatus is in the stationary configuration. |
