Abstract
Slip assemblies are provided for gripping drill pipe or other tubulars such that the load is distributed along the length of the dies of the slip segments rather than being concentrated at the lowermost dies within the slip segments. The load is distributed by the fact of using a load ring around the interior surface of each slip segment to allow the load ring to absorb part of the loading rather than have all of the load supported by the lowermost slip dies. In addition, resilient members are provided at the top surface of the uppermost die and also at the top surface of the die immediately underneath the load ring to better distribute the loading between the various slip dies and also to lessen the possibility of having gaps develop between the dies of the slip segments.
