Abstract
Pipe handling apparatus for transporting pipe in a pipe carrier between a pipe rack and a derrick floor wherein the pipe carrier is supported by a first cable and is manipulated between the pipe rack and the derrick floor by a second cable which is operably connected to a lateral displacement means mounted with the pipe carrier for lateral displacement of the pipe carrier and the pipe therein as the pipe carrier nears the derrick floor thereby to position the pipe for unloading at the derrick floor without detrimental contact of the pipe with any object to accomplish such lateral displacement.
Claims10
An apparatus for transporting pipe from a pipe rack to a derrick platform, and for transporting pipe from the derrick platform to a pipe rack, comprising:
- a. a first upright member;
- b. a second upright member spaced longitudinally apart from said first upright member;
- c. a first cable extending between said first and second upright member and normally disposed in a longitudinal substantially straight line between said upright members;
- d. support means mounted on said first cable for movement longitudinally along said first cable;
- e. a pipe carrier supported by said support means for transporting pipe therein;
- f. a second cable coacting with said carrier for moving said pipe carrier longitudinally relative to said first cable;
- and
- g. lateral displacement means coacting with said second cable for laterally displacing said pipe carrier relative to said longitudinally substantially straight line between said upright members as said pipe carrier approaches the area in proximity to said first upright member.
