Leslie Consulting invented the Parallel Rig concept, patented by CQMS, as a more cost-effective alternative to the UDD rigging dragline conversions originally patented by Bob Beatty. The research behind this work has made LC world leaders in understanding the principles behind these rigging systems. |

As a result LC also understands the implications of UDD on rigging design, bucket design and dragline control system requirements. With CQMS, LC has designed all of the UDD specific buckets, and are BMA approved certifiers for UDD bucket designs. |
