  • Patent number: 11312598
    Abstract: Described herein is a hoist fleet system including a head block and a guide fleet assembly. The head block includes a plurality sheaves having more than one diameter. The guide fleet assembly can be arranged proximate the head block such that an array of lift lines can be routed through the plurality of sheaves of the head block into the guide fleet assembly. The guide fleet assembly further includes a plurality of guide sheaves and a plurality of plates. The plurality of plates is configured to house the plurality of guide sheaves. The plurality of guide sheaves is positioned substantially orthogonal to the head block. The plurality of plates is further arranged such that the plurality of guide sheaves is arranged on more than one plane. The plurality of guide sheaves is configured to reduce the spacing of the lift lines.

  • Patent number: 8969741
    Abstract: A damming device for a conductor in a cable gland connector is described herein. The damming device can include a first portion having a first thickness of a flexible elastomeric material disposed between a first diameter and a second diameter. The damming device can also include a second portion having a second thickness of the flexible elastomeric material disposed between a third diameter and the second diameter. The damming device can also include a hole having the third diameter. The first diameter is greater than the second diameter, and the second diameter is greater than the third diameter. Further, the first thickness is greater than the second thickness. The damming device can be disposed, under tension, within a slot formed between a top portion of a compound chamber and a bottom portion of a union body.
