Dellner Brakes has introduced two groundbreaking new failsafe brakes to its SKP range that combine high power with modular, lightweight design.
Precision engineered in Sweden, the new spring-applied SKP failsafe brakes are designed to quickly stop rotary or linear motion in various applications such as cranes, winches, conveyors, deck machinery, draglines, wind turbines, oil rigs (draw works) and other machinery.
The new SKP 180, weighing in at just 315 kg, delivers braking force from 141 kN up to 226 kN through two brake housings, each containing a powerful spring applied piston. This hydraulically released disc brake consists of two symmetrical cylinder housings and can be supplied with or without a mounting stand.
The SKP 4 x 180, weighing 630 kg, combines two brake assemblies containing a total of four pistons to deliver braking force of up to 453 kN.
Dellner has also developed an offshore version of the brake, with corrosion protection and hard wearing paint and pistons that are specially designed to withstand harsh conditions.
The new SKP’s innovative modular design also means that Dellner can provide larger systems, combining several brake assemblies or customized housings with several pistons, to deliver even more braking power, tailored specifically for customers’ needs.
Dellner Brakes CEO Marcus Aberg said: “Innovation is at the heart of what we do here at Dellner, and these new SKP brakes are no exception. They have been developed in response to customer demand for a failsafe brake that’s lightweight and compact, but doesn’t compromise on strength or stopping power, and we are confident that this revolutionary design will set new standards in the market.”
The brakes come with a range of optional extras including mounting brackets; double sealing kits; brake pads made from several different friction materials; indicators that show brake pad wear, whether the brake is ON or OFF or needing adjustment; micro and/or proximity switches and electrical control boxes.
The brakes feature cylindrical guide pins that transmit the tangential braking force from the brake lining to the brake housing and mounting stand. As a result, the brake pistons are not subject to any radial forces, which makes the brakes and the cylinder seals last much longer.
As the brake lining wears, an extension of the brake piston through the adjustment nut indicates that adjustment is needed. The disc spring can be adjusted to compensate and maintain full brake capacity.
These new brakes are the latest in a long line of innovations from Dellner Brakes which includes the launch last year of the world’s very first fully automated electrical ‘stopping, turning and locking’ (eSTL) system (patent pending).
