A high-load slip system allows better transmission of loads from the slips (32) to the body (30). The cone (36) comprises longitudinal slots (42) and the body comprises tabs (46) which are disposed in those slots. The load is transferred from the slips to the cone and into the tabs which reside in the slots. The arrangement can be configured to share the load between the tabs extending from the body and the actual body itself after a small amount of collapse on the cone, leaving the body to support the cone, both through the tabs and on the outside diameter.
Cet ensemble cône de retenue mince, à capacité de charge élevée permet d'assurer une meilleure répartition des charges entre les coins de retenue et le corps. Le cône est pourvu de rainures longitudinales et des ailettes viennent se positionner dans celles-ci. La charge se déplace des coins vers le cône, puis dans les ailettes susmentionnées. Il est possible, grâce à cet agencement, de répartir la charge entre les ailettes partant du corps et le corps proprement dit et ce, après l'apparition d'un léger affaissement du cône, ce qui permet au corps de maintenir le cône, grâce aux ailettes et du fait de son propre diamètre extérieur.
