Abstract:
1. A system for transporting pre-assembled well-head equipment near a well-head location, comprising: a parallel set of two rail tracks located in a planar relation to a bed of a trailer, each track having a longitudinal axis that extends in parallel to each other; a transfer cart having a lower platform having a planar surface that is oriented in parallel to the longitudinal axis of said set of two rails, two pairs of wheels mounted on said lower platform, a first pair of wheels axially disposed to each other and a second pair of wheels axially disposed to each other, and each pair of wheels mounted on the lower platform at a fixed distance from each other and each pair of wheels being engaged with said parallel set of rail tracks, an upper “L” shaped platform having a horizontal planar surface and a vertical surface, said upper platform being pivotally mounted at a single pivot joint connected to one end of the planar surface on the lower portion of the transfer cart, said upper portion of the transfer cart being moved rotationally at the pivot joint mounted on the lower portion of the cart; a longitudinal support frame associated with said pre-assembled well-head equipment, said longitudinal support frame providing support to a pre-assembled equipment during movement of the equipment; said horizontal planar surface of the upper platform of the transfer cart being engaged with the bottom of the pre-assembled well-head equipment to provide support to the pre-assembled equipment, said pre-assembled well-head equipment being positioned substantially horizontally on the trailer bed when being transported, and said preassembled well-head equipment being pivotally rotated around the pivot joint coupled to the transfer cart to place said pre-assembled well-head equipment and support frame in a substantial vertical alignment for placement on a well-head.
