Modern technology has enabled design changes, advanced materials, and improved machining to bring this Cast Power Hammer up to 20th century standards.
The base is constructed utilizing two wide flange beams welded together, with a series of web stiffeners welded throughout. Then is fully welded to a 1" thick steel plate. The base weights an incredible 3,200 lbs.
The newly designed arms are now constructed out of Cast Iron, with more vibration absorption, better harmonics, a much better material suited for the hammer than welded plate steel.
The rotation of the hammer has two options. The original cone clutch style, controled with a hydraulic pedal. And also the option of the newly designed digital foot petal, and VFD. Both options have their benefits.
Each hammer is built with the option of the original dovetail rotating assembly or linear bearings. The dovetail assembly offers greater strenght, the linear bearing option offers more accuracy and precision. This hammer is incredibly user friendly and has minimal maintenance. Everything was built with longevity in mind.
The Davenport Machine Co Power Hammer stands at 8' tall and weighs 5,000 lbs. Using a 3 HP drive motor, the Hammer is rated for a 120 lb hit, and can hit up to 20 times a second. With the use of the larger 3" dies, there is increased stability. This proves to be extremely beneficial while making low crown panels due to the increased weight of the hit, and larger contact of the dies. Because of these factors, the speed at which a panel can be shaped is increased, which in turn decreases the fatigue on the user.
Die packages are available separately, and if purchased with the hammer are all 10% off. Other optional accessories are also available.
There is a 8 month construction process after the initial deposit is made.
