Abstract
A traction device using grooveless traction rollers. An angled roller mounting arrangement allows a number of line wraps to traverse back and forth across the rollers, following the spooling on the storage reel without the aid of a fairlead system for deployment. The device provides for automatic separation of successive line wraps on the rollers to eliminate snagging of connectors or accessories attached to the line.
Claims3
A traction device for line handling equipment comprising:
- a first driven roller mounted with an axis of rotation parallel to the axis of rotation of a storage reel;
- a second roller with an axis of rotation oriented at an angle to that of the first roller and within a second plane parallel to a first plane defined by the axis of rotation of the first roller;
- said first and second rollers being operative to receive a plurality of wraps of a line and wherein said angle is selected to provide the desired wrap spacing on the rollers;
- and
- slidable support means for the second roller allowing free displacement of the second roller axis within the second plane and in a direction generally normal to axis of rotation of the rollers, and operative to be displaced by the action of the line wraps seeking to maintain constant total wrap length while traversing back and forth across the rollers.
