Abstract:
A safety brake assembly for material or personnel transporting machinery, which provides a braking effect between a housing and two brake discs which rotate with respect to the housing, comprising:a housing having two friction surfaces facing each other and held apart by one or more spacing rods, each carrying a bush;the two brake discs disposed inwardly from the friction surfaces of the housing;an electromagnet assembly between the two brakes discs and having:an armature disc,two outwardly facing friction surfaces,resilient means to urge the outwardly facing friction surfaces apart and into frictional engagement with the two brakes discs, andan electromagnet to pull the friction surfaces together and out of engagement with the two brake discs; the brake discs being free to move in an axial direction; the electromagnet assembly being floatingly disposed between the two brakes discs thereby allowing free movement in the said axial direction, the electromagnetic assembly being constrained against rotational movement by the one or more spacing rods.
