STAINLESS STEEL ROLLER BUTTON

UNYIELDING

UNDER PRESSURE

 

Patterson Roller Buttons offer a unique design feature with substantial bases made of stainless steel. Tested extensively at high-cycle rates that mimic real life, they have been proven to 50 tons. By alleviating the downtime, hotwork, decreased productivity, and lower profits of broken roller buttons lead, the Patterson Roller Buttons can positively impact your operation's bottom line.

Key Features:

 

Horizontal Alignment Mounting System

Spring Loaded Vertical Assist

Performance Data

 Model 

RB-50SS

*Rated Load

50 Tons

**Working Line Load

50,000 lbs

* 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.

HOW

WE MAKE THEM

SAFER.

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 S.A.R.C. 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.

EASIER.

FASTER.

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.

Building a Multipart Tow: Splitting on the Head

This diagram shows the boat "faced-up" to two barges. This is called "splitting the head." The boat is centered on the stern coupling of the two barges. The capstan and a lock-line (2 inch poly-dac line) are used to hold the boat to the two barges until the face wires can be attached. The "face wires" hold the boat securely to the tow and enable it to steer the tow. Because of the torque and rudder power of river boats, tow boats require "backing wires" that lead towards the stern of the boat, This helps prevent the boat from "steering out" of the tow.
