HIS Hook Blocks

HIS Hook Blocks are 3-sheave units with an adjustable center sheave. As the center sheave is adjusted the bend radius is also adjusted.

HIS Hook Blocks are designed to accomodate cable requiring larger minimum bend radius.

For example, for a 36” bend radius for large, high voltage cable, the center sheave can be placed in the lowest of the three positions which would create a 36” bend radius and a 120° bend angle, which would create a less sharp angle.
  • Top Position:        18" Bend Radius       90° Bend Angle
  • Middle Position:    24" Bend Radius     105° Bend Angle
  • Bottom Position:   36" Bend Radius     120° Bend Angle

HIS Hook Blocks are used for guiding cable as required and typically not used for pulling cable around 90° bends.

Also available in 7" widths
