The HULK is 100% designed, machined, formed, manufactured & assembled in the USA.
Weighing in at 80 pounds, this machine is a real beast! With 4340 Chromoly axles, fully machined drive yoke, and powered by a two-ton bottle jack, there isn’t much that the Hulk roller can’t handle.
We currently offer 76 different die sizes profiled for round tube, round pipe, and square tube. We also have a full line of unique dies for rolling flat bar, handrail cap, rectangular tubing, and square tubing in a diamond profile. Most of our dies are also available in Delrin which is well suited for rolling anodized aluminum, copper, brass, and chrome finishes where abrasion or scratches on the material surface are not acceptable. The center drive dies are fully keyed to the drive axle to ensures smooth operation and a solid connection.
If you have any experience rolling tubing, you know that most machines have a few main issues; the material twisting as it is rolled and how difficult it is to make repeatable bends. We have addressed the first issue by implementing several key design features. The 4340 chromoly non-drive axles are machined down to a tolerance of +/-.003” and two adjustable shaft collars on each axle are used to keep the dies perfectly centered between the ¼” thick steel frame plates. This prevents any side-to-side play that can cause the material to corkscrew as it is rolled.
The second major cause of material twisting as it is rolled is play in the center drive yoke. There are several large radius rollers on the market that use a cast steel yoke or a formed piece of steel to hold the center drive roller in place. Unfortunately, cast and formed parts will never be perfectly square or straight. When the center yoke is not square, the drive die tends to contact the material you are rolling with uneven pressure, pushing your material to one side, and causing it to twist. The center drive yoke on the HULK is made of 3 pieces of ¾” thick steel which have been fully machined and bolted together to ensure a perfectly flat and square yoke. This means the downward force that the drive die exerts on the material is always straight down, thus preventing any twisting and helping to prevent irregular material deformation.
Another often overlooked issue many people experience when rolling tube is the challenge of creating repeatable radius bends. The HULK includes a high-quality digital read out height gauge that measures downward travel of the center drive die, making it easier to create the same arc over and over. To use the DRO, place your material in the roller then “zero” the height gauge when the drive die is barely touching the material. Roll one piece of material to the desired radius and record the location of the outer dies as well as the measurement displayed on the digital read out. If you need to create the same part in the future from the same material, just put the non-drive dies in the same location and roll until the DRO gives you the correct measurement. Easy!
Most rollers on the market use a large top-screw to apply downward pressure on the material and cause it to form a radius. Tightening the top screw can be quite difficult when working with thick-walled material or square tubing in general. The HULK uses a 2-ton bottle jack. This makes applying smooth, consistent downward force much easier. The 2-ton bottle jack is bolted to the top of the drive yoke to prevent any movement while under load and ensure it is always perfectly centered over your material.
To ensure smooth operation, all of the dies ride on high-quality roller bearing. The 3-way adjustable manual handle can be unbolted and replaced with an electric pipe threader that is available from Harbor Freight. Their pipe threader (item #62203) is an easy, simple to install add on that will take the cumbersome and tedious chore of rolling thick-walled tubing and turn it into an almost completely hands-free operation.
With its powder coated steel frame, internally threaded aluminum spacers, green powder coated handle and stainless-steel fasteners, this tubing roller is designed to look as good as it performs. The HULK is sold as shown above, except for the sheet metal base structure which is not included. It comes 90% assembled.
As a general rule of thumb, the Hulk Roller can roll round tubing and solid material (flat bar, square stock, etc,) to a 12" radius and square/rectangular tubing to a ~36"-48" radius.
The (4) 3/8" bottom mounting hole locations are 29" x 7.625" on center. The total footprint of the base plate is 30" x 8.625".
Dies can be purchased using the list above or by themselves. Each die size includes one drive roller and two non-drive rollers. You will not need a replacement drive axle since one comes with the tubing roller by default. We have over 1000 die sets on the shelf and 99.9% of the time we have every die size in stock.
Note: Recommended max wall thickness for Square Tube: 0.125"
Max wall thickness for round tube varies by size and material type. Contact us with any specific questions.
Note: Round Tube and Round Pipe are different materials. Please make sure to select the correct die for your material. If you have questions regarding the difference, please consult our FAQ page or send us an email at sales@swagoffroad.com
