Abstract
A system includes a collapsible trailer frame and a lifting mechanism coupled to the collapsible trailer frame. The lifting mechanism is configured to raise or lower a coil of pipe or a reel of pipe. The system also includes a braking mechanism.
Claims19
A system, comprising:
- a collapsible trailer frame comprising two portions configured to telescope toward or away from one another such that a collapsed system width is less than an expanded system width;
- a lifting mechanism coupled to the collapsible trailer frame, wherein the lifting mechanism is configured to raise or lower a coil of pipe disposed on an expandable drum assembly, wherein the lifting mechanism comprises:
- one or more hooks configured to engage the expandable drum assembly;
- one or more hydraulic cylinders coupled to the one or more hooks, wherein the one or more hooks are configured to engage the expandable drum assembly such that the expandable drum assembly is removable from the trailer frame and is movable in a vertical direction with respect to the trailer frame;
- and
- one or more vertical stops configured to block the expandable drum assembly from disengaging from the one or more hooks;
- a braking mechanism;
- at least two wheel assemblies coupled to the collapsible trailer frame, wherein each of the wheel assemblies comprises:
- a wheel frame;
- at least two wheels coupled to the wheel frame;
- and
- a pivot coupled to the collapsible trailer frame, wherein the pivot enables the wheel assembly to pivot up and down with respect to the collapsible trailer frame;
- and
- at least one stop plate coupled to the collapsible trailer frame and configured to block movement of the wheel frame about the pivot beyond a desired amount.
