eDrive™ Precision Roller Leveling System
Our patent pending eDrive technology employs tension leveling techniques for gauges .020" to .625". With today's laser cutting machines in widespread use, erasing the footprint of internal stresses in flattened metals has become more important than ever. The eDrive was developed to equalize these internal stresses while delivering superior flatness.

By splitting the gearbox into two independent drive sections, plunge can be increased and the final product significantly improved. We focus specific horsepower to the material at the point of plastification – while the exit side of the gearbox is more concentrated on pulling the material out of the leveler.

This is very important with today's demand for “Stay Flat™” – or what Bradbury has trademarked “Process Flat™” – materials. Better management of horsepower reduces wasted energy and makes the eDrive eco-friendly and one of the lowest cost systems to operate in the world. We use the same amount of horsepower; however, the computer control constantly monitors what is required while preventing the leveler from overloading. Testing has revealed significant energy savings during the normal run cycle. This results in money savings to you and provides superior control over the flatness of the strip.

We can also retrofit existing Bradbury roller levelers with this new drive technology. Owners of this rebuild claim that the leveler is easier to operate and produces flatter material. If you currently own a Bradbury leveler, ask us about the eDrive retrofit package. We can refresh the entire leveler and add the new drive/gearbox system at the same time.

The new Bradbury eDrive™ system (patent pending) was developed after discovering the mismatch of roll speeds as material makes its way through a leveler. This phenomenon was noticed when torque limiters on the drive shafts of the exit rolls were showing excessive wear as compared to the entry shafts. Further testing revealed that material was actually being forced through levelers from the front. With all leveler rolls of equal diameter and geared the same, material was “bunching up” internally, greatly reducing the stretching process required to equalize material shape. The plunge of the entry rolls has everything to do with yielding the material to a plastic state. Yet when the plunge was increased, the bunching would worsen, and horsepower consumption would increase with little material improvement being gained.
