Power management company Eaton today announced that the Airflex Floating Housing Brake, an air-cooled spring-applied brake featuring long-wearing friction material and a rugged rotating disc, is now available in sizes 130 and 138. Designed with a tapered shaft lock (TSL), exceptional friction life and “quick change” friction lining to reduce maintenance time and cost, the brake is built for heavy duty dragline equipment for surface mining operations.
The brake’s friction pads can hold up to 2400 E-stops before a friction change is needed, requiring replacement one or two times every three to five years, instead of up to six times per year. When replacement is required, the “quick change” friction lining can be replaced in minutes, instead of the hours required for traditional braking systems. The TSL also helps maximize service life by eliminating spline wear during freewheeling.
The Floating Housing Brake reduces rotational inertia as compared to typical caliper brake systems. With 20% less inertia on hoist functions and seven% less inertia on swing functions, the softer braking capability reduces thermal power loading, yielding softer braking and less friction and motor wear.
Airflex Floating Housing Brakes are compatible with a wide range of motors. The brakes are rated for 288,000 inch-pounds (in-lbs) to 432,900 in-lbs of torque.
