The Base and Top Housing in these photos are two main components used to build a Hydraulic Roller Leveler.
Hydraulic Roller Levelers have become the most versatile and efficient metal flattening machines on the market today. Adjustments are accomplished by moving only the Base portion of the Leveler. With brute hydraulic force, stress is neutralized while delivering a premium quality product day after day. Development of world class controls and a unique set of options have made these Levelers very productive and easy to operate, while maintaining outstanding stretching and flattening repeatability.
To begin the manufacturing process of these enormous fabrications, certified A36 grade steel plates, ranging in thickness from 2” through 8” were purchased from local steel warehouses and domestic steel mills. The plates were cut to size, with precision tolerances, on J & J Burning’s state of the art oxy fuel and plasma cutting systems. When the burned parts and structural steel details were ready, skilled craftsmen, known as Fitters, assembled the jobs per the customer’s specifications. Once the assemblies were complete, the Base and Top Housing went through a tightly controlled weld conditioning process, called “stress relief”. The weldments were loaded into furnaces set to 1,100 degrees Fahrenheit for a ten-hour cycle. A slow cooling process followed to complete the removal of stresses in all welds. After that, the fabrications were shot-blasted to clean the steel to a near white condition, which is an ideal surface for painting. The final painting of both parts was completed in our 40’ Devilbiss paint booth.
When the custom steel specialty components were completely inspected and ready to ship, they had a combined weight of more than 250,000 pounds.
We pride ourselves on being part of an elite group of large capacity metal fabricators in the United States that is able to successfully manufacture parts of this size. We have the experienced workforce and high quality standards that are required to meet the exacting standards of customers throughout the country.
