Roxtec sealing solutions are used to prevent water and steel process dust from entering outdoor cabinets and indoor control room containers of the Konecranes lifting equipment at SSAB’s steel works in Raahe, Finland.
The overhead traveling cranes must be operational at all times in a steel production process resulting in 2.5 million tons per year.
“We need good cable seals to avoid dust in the electrical cabinets, and Roxtec is a good way to seal around flat cables. The worst thing that can happen to us is a stop in the steel production,” says Jarmo Manninen, responsible for crane maintenance and work planning at SSAB.
Roxtec has helped SSAB and Konecranes handle a tough and frequent sealing challenge by providing sealing modules also for flat cables of many different sizes.
Konecranes started using Roxtec’s seals instead of cable glands in the mid 1990’s. Arto Vaaraniemi, leading electrical engineer of Konecranes, explains why the crane provider continues to specify Roxtec seals for all cranes. “Our customers want seals that are easy to install and that provide very good protection,” Vaaraniemi said. “When it comes to high IP ratings, Roxtec is the only seal we use.”
