| 20110206451 | Load Spreader Bar Pipe Connection Sleeve - The invention provides a spreader bar pipe connection sleeve for use in a spreader bar assembly. The pipe connection sleeve may include a flange having a first side and a second side, the first side may include a groove adapted for receiving an end of a first spreader pipe and the second side may include a groove adapted for receiving an end of a second spreader pipe. A first insertion part may include a distal end extending from the flange first side and may include a shoulder on the distal end, the shoulder being adapted for abutment with an inside diameter of the first spreader pipe. A second insertion part may include a distal end extending from the flange second side and a shoulder on the distal end. The shoulder may be adapted for abutment with an inside diameter of the second spreader pipe. The invention may include a fastener mechanism for securing at least one of the distal ends to one of the spreader pipes. The first and second spreader pipes may include different diameters and may include machined end plates. The grooves may extend outward from and/or recess into the flange. | 08-25-2011 |
| 20090064793 | Load test system - A load test system includes a test bed frame which extends horizontally along a first axis and includes two rolling beams moveably mounted securely in the test bed frame for being moved to desired position. The rolling beams have plural attachment locations for attaching a test lift device. A hydraulic power station is located spaced perpendicular from the test bed frame along a second axis and includes a hydraulic cylinder with a line connected to the hydraulic cylinder at one end, which is connectable to a test device at another end for applying a load when the test device is attached to the test bed. Beam members connect the hydraulic power station and the test bed frame to form a rigid structure. | 03-12-2009 |
