SELF-ALIGNING ROLLER CHOCKS
GROUNDED
IN INNOVATION
The Patterson patented Self-Aligning Roller Chocks (SARC) are the next evolution in boat to barge coupling. Effectively utilized for both face wires and wing wires, all models include optimized sheave materials for both synthetic rope and steel cable, rounded edges to minimize wear points, corrosion resistant construction utilizing stainless steel and protective coatings for extended life, and the extreme durability that you’ve come to associate with the Patterson name. We have also incorporated a variety of innovative features that are sure to help you do your job –Safer, Easier, and Faster.

* Rated Load (RL) – The total amount of continuous pull (load) allowed on the unit at any time. The maximum RL occurs when the maximum Working Line Load (WLL) is achieved and the rope is wrapped 180° around the sheave. This is equal to two times the WLL.
**Working Line Load – The amount of continuous allowable line tension on the unit.

Horizontal Alignment Mounting System
In the past, similar types of chocks could only align vertically. This helped extend the life of the rope, but allowed for dangerous side loading that could lead to permanent yielding of the product causing it to become non-functional, or worse, catastrophic failure. With the Patterson Horizontal Alignment Mounting System, the SARC becomes the first truly self aligning design, as the entire unit always orients itself to the center of the line pull, both vertically and horizontally, regardless of the angle.
Spring Loaded Vertical Assist
The protection of your rope is critical, both to ensure safe operating conditions, and to minimize the replacement cost of this expensive consumable. We get this, which is why we created the Spring Loaded Vertical Assist. Using a super high strength torsion spring mechanism, we effectively eliminate the majority of the weight of the sheave housing, allowing your chock to begin aligning with little to no line tension, even when using ultra light synthetic rope. This eliminates abrasion by keeping the rope where it belongs: in the sheave, keeping you safer, and saving you money.
