The "Plate Alignment Jack" is a jack that performs level adjustments hydraulically without the need for hammer strikes that cause noise. Traditionally, when aligning and temporarily welding steel plates, adjustments were made by striking with a one-handed hammer, followed by temporary welding. However, this method had issues such as noise impact on neighbors, inefficiency due to manual work, and negative effects on hearing. This machine solves these problems by using magnets to hold the steel plates in place and applying hydraulic pressure to align the plates. 【Features】 - For leveling (height) alignment of two steel plates - No hammer strike adjustments required - Cylinder pressure: 6.5 tons - Utility model No. 3144736 - Also available in an electromagnetic long press type For more details, please refer to the catalog or feel free to contact us.
