Abstract

A slewing ring brake for use in heavy machinery including earthworking machinery. The slewing ring brake includes a slewing ring with a tooth system and a support member which is mounted in a manner to allow rotary movement of the support member relative to the slewing ring. The slewing ring brake also includes a brake block displaceably mounted on the support member, the brake block being displaceable between a braking position and a freewheeling position. In the braking position, the brake block engages with the tooth system thereby preventing rotary movement of the support member relative to the slewing ring. In the freewheeling position, the brake block disengages the tooth system thereby allowing rotary movement of the support member relative to the slewing ring
