Abstract
A lift system particularly designed for transport of pipes from a first to a second elevated location includes first and second storage locations with a lifter component positioned therebetween. The lifter is positioned such that pipes at a first location can be easily picked off a first location by the lifter for transport to the second location. Fingers on the drive chains of the lifter offer a two-point spaced contact to each pipe whether picked off the location or placed thereon by the user. Upon each pipe reaching the upper end of the lifter the fingers return to the lower end which causes a deposit of the pipe onto a second elevated location, e.g., a storage location, truck bed or the like.
Claims15
A pipe lifting system comprising:
- a first storage rack including first and second spaced-apart above ground rails adapted for supporting a plurality of elongated pipes traversing a desired path of upstream travel, said rails defining a plane displaced from the ground;
- a second storage location upstream said first storage rack adapted for supporting a plurality of elongated pipes, said second storage location traversing said path of travel;
- means for elevating at least one of the pipes from said first rack to said second storage location, said elevating means positioned intermediate said first rack and second storage location, said elevating means having a first ground adjacent lower end positioned below said first and second rails of said storage rack and a second upper end positioned adjacent an end of said second storage location, said elevating means including means for pick up of at least one of the pipes positioned on said first rack upon a driven movement of said pick up means between said lower end and upper end of said elevating means and through said plane for deposit of the one pipe at said second storage location upon said driven movement of said pick up means from said upper end and towards said lower end;
- means for releasably connecting said upper end of said elevating means to said position adjacent said second storage location end, said means including:
- a bar traversing said end of said second storage location;
- bracket means having first and second ends, said first end extending from said upper end of said elevating means and a second free end presenting structure for a releasable attachment about said traversing bar.

A pipe lifting system comprising:
- a first storage location adapted for supporting a plurality of elongated pipes at an above ground position traversing a desired path of upstream travel;
- a second storage location upstream said first storage location adapted for supporting a plurality of the elongated pipes therein;
- a bar traversing said second storage location adjacent an end thereof;
- means for elevating at least one of the pipes from said first location to said second location, said elevating means positioned intermediate said first and second locations, said elevating means having a first lower end positioned below said first storage location and upwardly extending therefrom to present a second upper end releasably attached to said traversing bar and above said second storage location, said elevating means including means for a pick up of one of the pipes in said first storage location upon movement of said pick up means from said lower end and towards said upper end, a deposit of the pipe at said second storage location occurring upon a further movement of said pick up means from said upper end and towards said lower end.

A pipe lifting system comprising:
- a first storage location adapted for supporting a plurality of elongated pipes in an above ground position traversing a desired path of upstream path travel;
- a second storage location upstream said first storage location for the pipes in said first location;
- a bar traversing said second location at an input end thereof,
- means for sequentially elevating each one of said pipes from said first location to said second location, said elevating means including at least one beam having a first lower end positioned adjacent an end of said first storage location and a second upper end positioned at least adjacent said second storage location, said elevating means including a plurality of spaced-apart support flanges in continuous movement between said lower and upper ends of said at least one beam for underlying support of one of said pipes at said first location upon placement of one of the pipes on one of said flanges, the one pipe released from said flange support for deposit at said second location upon movement of said supporting flange from the upper end of said at least one beam and towards said lower end thereof;
- and
- a bracket extending between an upper end of said at least one beam and said bar, said bracket releasably associating said upper beam end with said second location.
