ELECTROMAGNETIC FAILSAFE CALIPER MOTION CONTROL DIVISION

The Hilliard MK Guide Rail Brake is designed for use on elevators, conveyors, cranes, or other devices requiring a spring-applied electromagnetically released brake. The patented MK brake can be applied to a guide rail or a brake disc. It is unique in that it is direct acting with only one moving part. The brake incorporates an electromagnetic coil that uses a voltage dropping circuit to minimize current draw and heat when the brake is released. Shipped with manual release bolts for easy assembly to the rail or disc, it can also be equipped with a manual release mechanism for a momentary release...

Optional manual release mechanism automatically returns closed when wrench is removed. Approximate Envelope Dimensions (in) BrakeType ^Dimension varies with rail or disc thickness

The Brakeboss electric brake controller features rectification from AC to DC, combined with Peak Inverse Voltage suppression and magnetic field over-energization for interface to the MK Rail Brakes. The control box input voltage is 230 VAC 50/60 Hz. The output to the brakes is 210 VDC for 1-2 seconds, during which time the brake releases. The voltage then drops to 105 VDC indefinitely to keep the brake in the released condition. The brake applies when power is removed (fail safe).

MK-1400 brake installed on the high speed shaft of a gearbox on top of a hoist. In this application the disc brake application acts as a holding brake when power is removed from the main drive. This theatrical stage lift incorporates eight MK-1400 brakes acting on four separate elevator T-Rails. These are secondary safety brakes that apply in the event of a drive chain failure. MK-1400 brakes are pin-mounted on the bridge drive of an overhead crane, ensuring the bridge doesn't drift during critical lift operations.

If the brake is for holding duty and no dynamic stops are made, reduce rated torque by 50%. Torque CalculationRated Torque = Braking Force x (Mac Radius - “X") in Lb-Ft Torque12 Data BrakeType
