Success is in the details

Machinery in the construction industry is often subject to heavy requirements. For example, the shovel of an excavator used in mining might have to shift 42m³ of material weighing 1.8t/m³– up to a total of 75t in one go. With such intensive loads in play, the connection elements of the swing bearing must be designed to cope. At Berrang, we begin to design the solution to such a challenge during the development phase by determining the preload forces in action. At a later stage, the friction coefficients are monitored in the series by using an in-house screw test stand – one of the largest in the world of its kind.

Every screw serves a purpose. The shape of the head, strength, surface finish, and thread are decisive factors for each individual application. Is that really true?

A long-standing customer ordered a new screw from us. It was a standard product. A short time before this, a similar screw was ordered in large quantity. This led us to ask whether the customer really needed two different products. Perhaps it would make more sense to use the same screw for both applications?
