Benzler’s series BD screwjacks are the solution if you need to lift, lower, push or pull a load. The product is ideally used together with positioning.
Since the product introduction 60 years ago, we have solved countless tasks with our screwjacks. The applications have ranged from simple lifting devices to lifting e.g. manholes in large power plants, or road bridge openings.
In the paper industry, Benzler’s BD screwjacks are often used for positioning blades, lifting & maintenance positioning of rolls, etc.
This product is often also used when you want an alternative to a hydraulic cylinder, e.g. for lifting tables and the like in the food or pharmaceutical industry. For these industries, we often suggest a stainless steel jack variant.
The series BD consists of a comprehensive line, with performance from a few kilograms to hundreds of tons. We manufacture screwjacks with both trapezoidal screw and ball screw.
The product catalogues are extensive and in them you can find, for example, protective bellows or protective pipes as well as many connection details to the surrounding environment.
Jack drives are all individual and very rarely resemble each other. \nHere at Benzlers are well aware of this, so it is natural for us to, as far as possible, adapt our product to the customer’s operation. Through this, we have also built up a great deal of experience in driving screwjacks synchronously via advance gears, intermediate shafts or electronics.
